Splenic involvement by aggressive malignant lymphomas of B-cell and T-cell types. A morphologic and immunophenotypic study.

To determine whether there are any consistent morphologic differences between B-cell and T-cell aggressive non-Hodgkin's lymphomas of the spleen, the authors analyzed 16 spleens involved by mixed cell (1 case) or large cell (15 cases) lymphomas. Immunologic data were derived from cell suspensions or frozen tissue in each case. Five cases had a T-cell phenotype, and 11 were B-cell. Morphologic features favoring a T-cell phenotype included epithelioid histiocytic reactions, confinement of the lymphomas to the splenic T-zones (periarteriolar lymphoid sheath and marginal zone), and clear cell or polymorphous cytologic features. Features favoring a B-cell phenotype included multiple discrete nodules in the white pulp, large coalescent tumor nodules in association with small lymphocytic lymphoma, and large non-cleaved or immunoblastic plasmacytoid cytologic characteristics. Four cases were unusual because most neoplastic large cells were distributed diffusely or formed only small aggregates in the red pulp without definite tumor masses or nodules involving the white pulp. Because of this distribution and the frequently encountered erythrophagocytosis by benign-appearing histiocytes, these cases resembled malignant histiocytosis. A T-cell phenotype was predicted for all four cases; however, only one case, a lymphoma with polymorphous cytologic characteristics, was of T-cell lineage. The other three cases were of B-cell lineage. The authors' results indicate that in most instances the B-cell or T-cell nature of aggressive splenic lymphomas is predictable from the distributional and cytologic features. As in lymph nodes, there are cases for which the morphologic characteristics of B-cell and T-cell lymphomas are indistinguishable.

Monocytoid B-cell lymphoma in patients with Sjögren's syndrome: a clinicopathologic study of 13 patients.

A recent clinicopathologic study of a series of patients with monocytoid B-cell lymphoma (MBCL) indicated that there is a frequent association between MBCL and Sjögren's syndrome (SS) and raised the possibility of a relationship between these two disease entities. To further investigate the possible relationship of MBCL and SS, we studied pathologic and clinical characteristics of 13 patients with MBCL who had clinically documented SS. In all patients, the lymphoma had the characteristic morphologic features of MBCL, and immunologic and molecular hybridization studies confirmed the B-cell nature of the lymphoma. Twelve of the 13 patients were female, with a median age of 66 years at diagnosis. Eleven had localized disease and presented with either salivary gland or cervical lymph node enlargement; one patient presented with a breast mass, and another with generalized lymphadenopathy and hepatosplenomegaly. In five of 13 patients, the MBCL was associated with or progressed to large cell lymphoma. In two patients, there was bilateral involvement of the parotid gland; one had a synchronous high-grade lymphoma in both parotid glands. In two patients, bone marrow biopsies showed involvement by MBCL. Eleven patients are alive 2 to 55 months after the diagnosis of MBCL. One patient died with the disease 8 months after the initial diagnosis. Another patient died of an unrelated cause without evidence of disease 16 months after the diagnosis of MBCL. We conclude that there is a more than fortuitous association between MBCL and SS. This concept is consistent with previously reported observations of reactive monocytoid B cells in patients with benign lymphoepithelial lesions of salivary glands, which may result from selective homing of reactive monocytoid B lymphocytes to the benign lymphoepithelial lesions and their subsequent neoplastic transformation.

Lymphoid hyperplasia and malignant lymphoma occurring in the ocular adnexa (orbit, conjunctiva, and eyelids): a prospective multiparametric analysis of 108 cases during 1977 to 1987.

We performed a prospective multiparametric correlative clinical, histopathologic, and immunologic analysis of 117 ocular adnexal lymphoid proliferations developing in 108 patients between October 1977 and July 1987. The ocular adnexal lymphoid proliferations were distributed among the 108 patients as follows: orbit 69 (64%), conjunctiva 30 (28%), and eyelids nine (8%). The 117 ocular adnexal lymphoid proliferations were classified as follows: polyclonal lymphoid hyperplasia, 32 (22 orbit, nine conjunctiva, one eyelid) (27%); monoclonal B cell lymphoma, 81 (48 orbit, 25 conjunctiva, eight eyelid) (69%); null cell lymphoma, one (orbit) (1%); and histologically indeterminate, three (one each: orbit, conjunctiva, eyelid) (3%). Patients presenting with ocular adnexal polyclonal lymphoid hyperplasia and monoclonal B cell lymphoma, and patients developing unilateral and bilateral ocular adnexal lymphoid proliferations did not differ significantly with respect to age, sex, presenting complaints, duration of symptoms, or ophthalmic findings. Classifying ocular adnexal lymphoid proliferations into benign and malignant categories by histopathologic criteria and into polyclonal and monoclonal B cell categories by immunophenotypic criteria was not useful in predicting eventual outcome, including the occurrence of extraocular lymphoma. However, the clinicopathologic characteristics did differ according to the anatomic site of involvement and histopathology of the ocular adnexal lymphoid proliferations. Lymphoid infiltrates of the conjunctiva were associated with a lower incidence of extra-ocular lymphoma (20%) than were those of the orbit and eyelid, 35% and 67%, respectively (statistically significant, P less than .03). Ocular adnexal small lymphocytic and intermediate lymphocytic lymphomas were less often associated with extra-ocular lymphoma than were ocular adnexal lymphomas of all other histologic types, 27% and 46%, respectively (P less than .09). However, the single most important and statistically significant prognostic factor in these patients was the extent of disease at the time of presentation with an ocular adnexal lymphoid proliferation (P less than .001). Eighty-six percent of patients presenting with a unilateral or bilateral clinical stage lE ocular adnexal lymphoid proliferation, regardless of the histopathology or the immunophenotype, had a benign indolent clinical course and failed to develop ocular or extra-ocular lymphoma during a median follow-up period of 51 months. The results of this study substantially improve our understanding of extranodal small lymphocytic proliferations in general, and those of the ocular adnexa in particular.

A clinicopathologic study of malignant lymphomas of the nose, paranasal sinuses, and hard palate, including cases of lethal midline granuloma.

Malignant lymphomas of the nose, paranasal sinuses, and hard palate show marked clinicopathologic, immunologic, and prognostic diversity. The clinical features and pathologic spectrum of these lesions were studied in 20 cases (11 female and 9 male cases) with a mean age of 51 years at initial presentation. Malignant lymphomas of the large cell type were most frequently encountered (11/20). The next largest category was malignant lymphoma, diffuse, mixed small and large cell type (six of 20). Two thirds, 13 of 20 cases, had morphologic features suggestive of peripheral T-cell lymphomas. Necrosis, an angiocentric growth pattern, and epitheliotropism were found in nine, eight, and three cases, respectively. Of ten cases immunophenotyped on fresh-frozen or fixed, paraffin-embedded tissue sections, eight had a T-cell phenotype and two had a B-cell phenotype. Of 17 patients with sufficient follow-up data, ten are alive (median follow-up 33 months) and seven are dead (median survival 12 months). Patients with clinical Stages IE and IIE did not have a superior 5-year survival to those with more advanced disease. Histologic type also did not correlate with survival but this may be due to the aggressive histologic grade of the majority of cases and the retrospective nature of this study. The authors conclude that, despite the overall high-grade histologic type, the pathologic spectrum of malignant lymphomas involving this anatomic region is broad. Furthermore, some cases do not fit well into the National Cancer Institute (NCI) Working Formulation but more closely resemble the histologic features of peripheral T-cell lymphomas described in Japan.

Small lymphocytic lymphoma: a clinicopathologic analysis of 268 cases.

We analyzed specimens from 268 patients with small lymphocytic lymphoma (SL) to identify prognostic factors significant for survival. These patients were staged and treated according to the protocols of the Cancer and Leukemia Group B, Eastern Cooperative Oncology Group, Southeastern Cancer Study Group, and the Southwest Oncology Group. Univariate analysis showed that a large-cell grade greater than I, WBC greater than 10,000/microL, hemoglobin (Hgb) less than 11 g/dL, age greater than or equal to 55 years, and failure to respond to treatment were all poor prognostic factors. Multivariate analysis showed that large-cell grade, age, degree of capsular invasion, and symptom type were independently associated with survival. Separate analyses of cases with and without leukocytosis indicated differences in survival. In patients without leukocytosis, age, presence or absence of anemia, and treatment response were significant prognostic variables; in patients with leukocytosis, large-cell grade, presence or absence of anemia, symptom type, and treatment response were significantly related to survival. Multivariate analysis showed that age was the only significant independent prognostic variable in patients without leukocytosis; in patients with leukocytosis, symptom type, large-cell grade, and bone marrow involvement were independently associated with survival. We conclude that several parameters, both clinical and pathologic, should be assessed at the initial diagnosis of SL to predict prognosis better.

Monocytoid B-cell lymphoma. Clinicopathologic study of 21 cases of a unique type of low-grade lymphoma.

The morphologic and immunologic features of three cases of an unusual and distinct B-cell lymphoma were recently described and termed monocytoid B-cell lymphoma (MBCL) because of the striking resemblance of the neoplastic cells to reactive monocytoid B-lymphocytes. The morphologic spectrum and the clinical behavior of MBCL were investigated in a series of 21 patients. This study indicates that patients with MBCL usually present with lymphadenopathy and Stage I or II disease. MBCL also occurs at extranodal sites including the salivary gland. Because four of the patients with MBCL had Sjögren's syndrome with characteristic laboratory profiles, these results raise the possibility that there may be a relationship between MBCL and Sjögren's syndrome. Eight patients were male and 13 female (M:F = 1:1.6), and MBCL primarily involved the elderly (median age, 66 years). The most striking clinical findings were high percentages of complete remissions and long survival times indicating that MBCL is a low-grade lymphoma. Of 21 patients investigated, 18 were in complete remission at the time of completion of this study. Two patients died with the disease and one was lost to follow-up. Patients with localized MBCL may have a better survival rate than those with generalized disease. Like other low-grade lymphomas, MBCL can progress to a higher grade lymphoma of large cell type. Unlike other low-grade lymphomas, in MBCL splenomegaly, bone marrow involvement, and leukemic conversion are uncommon.

T-cell-rich lymphoproliferative disorders. Morphologic and immunologic differential diagnoses.

To differentiate peripheral T-cell lymphomas (PTCL), the authors evaluated the results of T11 monoclonal antibody studies on consecutive cell suspensions prepared from 509 lymph nodes from various lymphoproliferative disorders (LPD). They used T11 (CD2) positivity to identify those LPD in which the content of T cells was high. There were 266 (52%) cell suspensions which contained more than 50% T11-positive cells. More than 75% of the following non-Hodgkin's lymphomas had over 50% T11-positive cells: diffuse mixed cell (DM), diffuse atypical poorly differentiated lymphocytic and lymphoblastic lymphomas; mycosis fungoides; and true histiocytic lymphoma. Eleven cell suspensions had more than 90% T11-positive cells; four were involved by B-cell lymphomas. The cell suspensions prepared from nine of 14 diffuse large cell lymphomas of the T-cell type had more than 50% T11-positive cells. Of these, three of five cases of the polymorphous subtype had fewer than 50% T11 cells, but six of seven lymph nodes of the clear-cell type had more than 50% T11-positive cells. Each of seven DM samples of the T-cell type contained over 50% T11 cells; none had a polymorphous appearance. In the 112 cases of reactive LPD studied, more than 75% of cases of necrotizing lymphadenitis, dermatopathic lymphadenitis, angioimmunoblastic lymphadenopathy, and those with lymph nodes with no specific reactive pattern had more than 50% T11-positive cells. The authors' findings indicate that T11 positivity is a reliable T-cell marker in reactive and neoplastic LPD except for those cases of PTCL with a polymorphous appearance; these tend to lose T11-expression. A multi-parameter diagnostic approach is required in the following LPD: (1) PTCL which are T11-negative; (2) PTCL of small lymphocytic type having an unremarkable T-cell phenotype; (3) SIg-negative B-cell lymphomas which are rich in nonneoplastic T cells; (4) non-Hodgkin's lymphomas with minimal disease which are rich in reactive T cells; and (5) polymorphous large cell proliferations.

Variability in interpretation of immunohistologic findings in lymphoproliferative disorders by hematopathologists. A comprehensive statistical analysis of interobserver performance.

Eight hematopathologists independently reviewed 56 consecutive cases of benign and malignant lymphoproliferative disorders (LPD) to determine: (1) the degree of interobserver agreement on the interpretation of immunologic findings on fresh-frozen sections alone and on that of the immunologic findings in conjunction with corresponding hematoxylin and eosin (H & E)-stained histologic sections; (2) whether prior knowledge of morphologic characteristics influences the interpretation of immunohistologic sections; (3) whether immunologic phenotype could be predicted reliably based solely on study of histologic sections; and (4) the significance of immunologic data as an aid in the interpretation of histologic sections. The study was carried out in three independent review sessions consisting of (1) review of immunohistologic sections only, (2) review of the same immunohistologic sections together with histologic sections, and (3) review of the histologic sections alone. A consensus diagnosis was defined as agreement of five or more pathologists on the final diagnosis and identification of the immunophenotype. When the authors compared the total number of major disagreements in the first review session with those in the second, the accuracy of the determination of immunophenotype in the second session was clearly superior (P less than 0.05). Similarly, the total number of major disagreements in the second review session was significantly lower than that in the third review session (P less than 0.001). When histologic diagnoses in the second session were compared with those in the third session, it became apparent that the immunologic data helped the pathologist to correct major misinterpretations in 14 cases (25%). This study is the first to demonstrate quantitatively that (1) knowledge of morphologic features influences and greatly enhances the accuracy of the interpretation of immunologic findings, (2) the immunophenotype of LPD cannot be predicted based on morphologic findings alone, and (3) immunologic findings improve the accuracy of interpretation of histologic findings in situations in which a diagnosis cannot be made from morphologic features only.

Lymphoid neoplasia associated with the acquired immunodeficiency syndrome (AIDS). The New York University Medical Center experience with 105 patients (1981-1986).

We identified 105 patients with lymphoid neoplasia associated with the acquired immunodeficiency syndrome (AIDS) at the New York University Medical Center from 1981 through 1986: 89 had non-Hodgkin lymphoma; 13, Hodgkin disease; and 3, chronic lymphocytic leukemia. Immunophenotypic and antigen receptor gene rearrangement analysis showed the B-cell origin of all non-Hodgkin lymphomas studied and the clonal suppressor-cytotoxic T-cell subset origin of the chronic lymphocytic leukemias. We classified 69% of the non-Hodgkin lymphomas as high grade (small, noncleaved and large cell, immunoblastic-plasmacytoid) and 31% as intermediate grade (diffuse large cell). Each histopathologic category was correlated with distinct clinical features, including a statistically significant difference in median survival. Patients with Hodgkin disease had an atypical, aggressive clinical course, whereas patients with T-cell chronic lymphocytic leukemia had an indolent clinical course. These studies show the clinical, morphologic, and immunophenotypic spectrum of AIDS-associated lymphoid neoplasia, that the natural history of Hodgkin disease is altered in patients with AIDS, and support the Centers For Disease Control's recent revision in diagnostic criteria for AIDS to include intermediate-grade diffuse, aggressive non-Hodgkin lymphomas occurring in patients seropositive for human immunodeficiency virus.

Reactive lymphadenopathies.

Reactive lymphadenopathies often pose a diagnostic problem. The distinction of a reactive from a neoplastic lymph node requires the application of general histologic criteria that traditionally have involved the evaluation of cytologic features including cellular polymorphism v monomorphism and the presence or absence of cytologic atypia. Although these cytologic criteria remain valid, they are not inviolate and exceptions exist that may result in diagnostic ambiguity. In addition, the interpretation of a reactive process in a lymph node is predicated on the evaluation of the dominant histologic architectural pattern and on a systematic approach to the diagnosis. The patterns specifically include whether the nodal architecture is predominantly diffuse, mixed interfollicular and follicular, follicular, or sinusoidal. Under each of these dominant architectural configurations, a host of benign reactive diagnoses may be assigned. An awareness of the various diagnostic categories for each major histologic pattern, the range and subtleties of their histologic expression, and the application of new methods, such as immunology to determine clonality, have resulted in simultaneous narrowing of the diagnostic possibilities and expansion of our comprehension of the reactive lymphadenopathies.

Antigenically defined subgroups of lymphoblastic lymphoma. Relationship to clinical presentation and biologic behavior.

A large panel of monoclonal antibodies and polyclonal antisera were used to ascertain the immunophenotypic characteristics of 36 lymphoblastic lymphomas (LBL). Results showed that this group of lymphomas have significant immunologic heterogeneity. Of the 36 cases, 33 were positive for T-cell antigens; among these, 22 cases were classified as T-cell LBL (TLBL, Group 1) based on their expression of T-cell-restricted and T-cell-associated antigens, and five expressed the common acute lymphoblastic leukemia antigen in addition to T-cell-associated antigens (Group 2). Six cases showed strong reactivity with anti-Leu-11 antibody, which defines a specific subtype of lymphocytes considered to have a natural killer (NK) function (Group 3). Two additional cases had a "pre-B" cell phenotype (Group 4), as determined by reactivity with BA-1 and BA-2 monoclonal antibodies, which react with immature and pre-B-lymphocytes. The neoplastic cells in the remaining case showed monoclonal surface membrane immunoglobulin of the IgMD heavy chain and kappa light chain type (Group 5). Despite immunophenotypic heterogeneity, the morphologic features were essentially similar in all cases. When the clinical features for each immunologic group were compared, however, two statistically significant findings resulted: (1) the frequency of mediastinal masses was highest in TLBL (Group 1, P less than 0.01), and (2) the male-female ratio was significantly lower in patients with LBL expressing NK-associated antigens (Group 3) than in the other groups of patients (P less than 0.01). Our data indicate that LBL can be divided into several immunologic subtypes; larger, prospective clinicopathologic studies are required to determine the clinical significance of the immunophenotypic classifications of LBL.

Lymphoblastic lymphoma expressing natural killer cell-associated antigens: a clinicopathologic study of six cases.

We describe six patients with lymphoblastic lymphoma (LBL) whose neoplastic lymphoid cells expressed surface antigens associated with natural killer (NK) cells. The six cases were selected from a series of 38 specimens diagnosed as LBL based on morphologic criteria and further subclassified by the use of an extensive panel of monoclonal and polyclonal antibodies. Although the morphologic features in all six cases were similar to those previously reported for LBL, their expression of NK-associated antigens was unique. All cases were positive with anti-Leu 11b, an antibody which appears to define a specific subtype of lymphocytes considered to have NK function; and all cases expressed T11, a T-cell-restricted antigen. The most commonly encountered immunophenotype of our cases of LBL was: Leu 11b+, T11+, Leu7+, TdT+, Leu 3a+, Ia+, pre-B-, and B-. As compared with more classical LBL of T-cell type, LBL of NK-cell type in our series occurred primarily in females and non-whites. Whereas treatment of classical LBL by multi-agent chemotherapy may lead to long-term survival, only two of our six patients were long-term survivors. The data derived from this study raise the possibility that LBL with the antigenic phenotype of NK cells may represent a biologic subtype of LBL.

Surgical management of lymphomas involving the chest.

The efficacy of surgical judgments in the management of thoracic lymphoma was studied through review of 34 patients with primary mediastinal lymphomas, 30 patients who needed one or more thoracic operations after treatment of extrathoracic lymphomas, and 5 patients with primary lymphocytic infiltrates (PLI) of the lung. In all patients with primary lymphocytic infiltrates of the lung, thoracotomies were required in order to establish the correct diagnosis. Patients with primary mediastinal lymphoma required 74 surgical procedures (2.2 per patient) to establish the correct diagnosis. In retrospect, 40 operations were not beneficial. The procedures that provided diagnostic samples were 15 anterior mediastinotomies, 8 full thoracotomies, 3 median sternotomies, and 8 lesser procedures such as mediastinoscopy. Patients who needed thoracic procedures after treatment of extrathoracic lymphomas had 41 thoracic operations (1.37 per patient). Five operations were needed to manage complications of thoracic lymphoma or its therapy. To evaluate new radiographic findings, there were 35 operations (1.3 per patient) at a mean interval of 5.0 years following initial treatment; the findings were recurrent lymphoma in 62% and new lesions in 38% of patients. Among new lesions, there were 2 bronchogenic cancers; 9 enlarging mediastinal-pleural masses were not caused by lymphoma. The accurate diagnosis of thoracic lymphoma or new thoracic lesions in patients with lymphomas usually requires enough tissue for immunophenotyping. Providing adequate tissue samples and treating new lesions that are not lymphomas often require major thoracomediastinotomies for immunophenotyping.

Mitotic counts in follicular lymphomas.

Increased mitotic activity is associated with significantly shorter patient survival in some of the subtypes of diffuse non-Hodgkin's lymphomas. This study on 105 cases of follicular lymphoma was undertaken to determine the clinical significance of mitotic activity in follicular lymphomas. For each case, two pathologists independently counted mitotic figures in 20 random high-power fields. The difference of the average mitotic counts over 20 high-power fields for the two pathologists showed a Gaussian distribution with a median difference of -0.26 counts per high-power field and a standard error of 0.10 per cent. In 94 cases (91 per cent), the difference was less than two mitotic counts per high-power field, indicating good interobserver agreement. There was a statistically significant difference in mitotic counts between subtypes of follicular lymphoma as well as a gradient among subtypes, with the lowest mitotic activity in the poorly differentiated lymphocytic subtype and highest in the undifferentiated subtype. A multivariate statistical analysis of clinical and pathologic variables showed that mitotic figures were not of prognostic significance.

Monoclonal small (well-differentiated) lymphocytic proliferations of the gastrointestinal tract resembling lymphoid hyperplasia: a neoplasm of uncertain malignant potential.

Three histologically benign-appearing or diagnostically equivocal small lymphocytic proliferations of the gastrointestinal tract were examined by fresh-frozen section immunohistologic techniques. In one case, a dense infiltrate in the small intestine, consisting of small lymphocytes with round nuclei, was limited almost entirely to the mucosa. In another case, a localized colonic polyp was formed by mucosal and submucosal lobules of benign-appearing lymphoid aggregates with centrally located germinal centers. The third case, a penetrating gastric ulcer, was surrounded by histologically hyperplastic lymphoid tissue which included germinal centers. The small lymphocytes in all three cases were strongly positive for B-cell-associated antigens (B1, B2, BA-1), and all exhibited monoclonal light-chain restriction. Even though treatment consisted only of surgical resection of the lesions, no patient has had progressive disease during follow-up periods ranging from 24 to more than 50 months. We believe that the infiltrates in these cases are analogous to the morphologically benign monoclonal small lymphocytic proliferations common to the lung and orbit and that they have an uncertain, but probably low, malignant potential.

Recognition of hairy cell leukemia in a spleen of normal weight. The contribution of immunohistologic studies.

A 68-year-old man with known hairy cell leukemia (HCL) underwent splenectomy; the spleen weighed only 140 g. Microscopic examination of the spleen revealed no clear diagnostic evidence of HCL, but there was an unusual and suspicious subendothelial lymphoid infiltration of the trabecular veins. Cell suspension studies also were not diagnostic because a monoclonal B-cell population could not be defined. Alternatively, when we focused on the subendothelial infiltrate in the frozen sections prepared for immunohistochemical studies, the findings indicated that the subendothelial cells were monoclonal B-cells (IgG, kappa). Staining with monoclonal antibodies disclosed the phenotype Tac+, Leu-14+, Leu-M5+, B2-, BA-1-, and BA-2-, a phenotype characteristic of HCL. In this case, an unusual but nondiagnostic morphologic finding provided guidance for the correlative immunophenotypic analysis of the same site in frozen sections and thereby allowed a definitive diagnosis.
