Necrotising lymphadenitis of Kikuchi and Fijimoto in Sri Lanka.

We present the clinicopathological features of 10 patients with Kikuchi's lymphadenitis. It is important to distinguish this unusual form of necrotising lymphadenitis, both clinically and histologically, from lymphoma and infective lymphadenitis, including mycobacterial infection. The 10 lymph node biopsies studied were from young adults (9 women) with fever, cervical lymphadenopathy and elevated ESR. This is the first documentation of this condition in Sri Lanka. This benign self-limiting condition can be mistaken for lymphoma or infective lymphadenitis.

A distinctive cytologic pattern for diagnosing tuberculous lymphadenitis in AIDS.

Tuberculous lymphadenitis (TL) is a very common infection in human immunodeficiency virus (HIV)-infected patients. We performed fine-needle aspiration biopsy (FNAB) of enlarged lymph nodes in 57 HIV-infected patients to evaluate its usefulness in this population. We observed three cytologic patterns in 21 patients diagnosed as having TL: granulomatous lymphadenitis (GL) in 4 FNABs, necrotizing granulomatous lymphadenitis (NGL) in 7 FNABs, and necrotizing lymphadenitis (NL) in 12 FNABs. GL and NGL are already well-known and considered to be highly suggestive of TL. Our results support the idea that NL should have the same diagnostic value as GL or NGL. In the group of 12 patients with NL, TL was confirmed in 11 by microbiologic methods (7 by a positive Ziehl-Neelsen stain and 4 by a positive Löwenstein culture) and in the remaining patient by a biopsy that showed NGL with acid-fast bacilli. We conclude that FNAB is a useful, inexpensive, and safe technique for diagnosing TL in HIV-infected patients. The finding of a NL pattern is suggestive enough of TL to start antituberculous treatment.

Penicillium marneffei mesenteric lymphadenitis in human immunodeficiency virus-infected children.

UNLABELLED: Disseminated P. marneffei infection is one of the common opportunistic infections seen in HIV-infected patients in Southeast Asia. We report 3 cases of HIV-infected children with mesenteric lymphadenitis presented with prolonged fever and abdominal pain. The first two patients were diagnosed as peritonitis and acute appendicitis prior to exploratory laparotomy. Operative findings revealed multiple enlarged mesenteric lymph nodes. Histopathologic findings of mesenteric lymph nodes biopsy were characteristic for P. marneffei infection. Mesenteric lymphadenitis in the last patient was diagnosed by abdominal ultrasound. All three cases had positive blood and bone marrow cultures for P. marneffei. These patients were treated with amphotericin B. Fever declined in 3-6 days. The first two patients survived but the last one subsequently died from underlying hemophilia A (GI bleeding). CONCLUSION: Acute mesenteric lymphadenitis can be one of the unusual manifestations caused by P. marneffei. Southeast Asia is an endemic area for P. marneffei and is severely affected by acquired immunodeficiency syndrome epidemic. Therefore, mesenteric lymphadenitis should be considered in HIV-infected persons who present with prolonged fever and abdominal pain.

Combined use of fine-needle aspiration cytologic examination and tuberculin skin test in the diagnosis of cervical tuberculous lymphadenitis. A prospective study.

A prospective study to evaluate the efficacy of combined use of fine-needle aspiration (FNA) cytologic examination and Mantoux test in the diagnosis of cervical tuberculous lymphadenitis was carried out. Tuberculin reactions were determined in 59 control subjects. Preoperative FNA cytologic examinations and Mantoux tests were performed on 74 patients with cervical lymphadenopathy. The lymph nodes were then excised and examined histologically and cultured for mycobacteria. Forty-eight, 22, and 4 patients had histologically confirmed tuberculous, non-specific, and malignant lymphadenopathy. Fine-needle aspiration cytologic examination alone could detect cervical tuberculous lymphadenitis in 37 patients (77%). The predictive value of a strong tuberculin reaction for mycobacterial infection was 100%. The combined use of a Mantoux test and FNA cytologic examination was able to diagnose 43 (90%) of 48 cases of tuberculous lymphadenitis cervical preoperatively. Combined use of FNA cytologic examination and Mantoux test was efficient in the diagnosis of tuberculous lymphadenitis.

Importance of human immunodeficiency virus-associated lymphadenopathy and tuberculous lymphadenitis in patients undergoing lymph node biopsy in Zambia.

The relative importance of human immunodeficiency virus (HIV)-associated lymphadenopathy amongst patients presenting for lymph node biopsy in Central Africa is unknown. HIV-1 serology and histology of patients undergoing superficial lymph node biopsy during 1989-1990 in Lusaka, Zambia, were examined in a prospective cohort study of HIV serology and by retrospective review of laboratory records. Of 727 lymph nodes biopsied in Lusaka in 1989-1990, 380 (52 per cent) showed tuberculous lymphadenitis, 160 (22 per cent) histology suggestive of primary HIV lymphadenopathy and 66 (9 per cent) nodal Kaposi's disease. HIV serology was tested in 280 adults and was positive in 91 per cent (255 patients), including 89 per cent (153 of 171) of those with tuberculous lymphadenitis, 98 per cent (63 of 64) of those with histology suspicious of primary HIV lymphadenopathy and all (24 of 24) with nodal Kaposi's disease. Other HIV-associated lymphadenopathy included nodal lymphomas and lymphoepithelial cysts. HIV serology was tested in 22 children and was positive in eight, including four of 14 with tuberculous lymphadenitis. It is concluded that HIV-associated lymphadenopathy, especially tuberculous lymphadenitis, is very common amongst patients presenting for lymph node biopsy in Central Africa.

Atypical mycobacterial cervicofacial lymphadenitis in children: a disease as old as mankind, yet a persistent challenge.

The diagnosis of atypical cervicofacial lymphadenitis is often not readily clinically apparent. Parents may bring a child to the physician's attention long before the development of the classic findings. When assessing the child with acute-onset cervicofacial lymphadenitis, there are 2 imperative clinical determinations: Is the lymphadenitis of viral, bacterial, or mycobacterial etiology? If of mycobacterial etiology, is it an atypical or tuberculous mycobacterial process? The goal in management is to avoid misdiagnosis and lengthy duration of symptoms before appropriate therapy is instituted. This paper includes a case study-based review of the evaluation, diagnosis, and management of cervicofacial lymphadenitis in children due to atypical mycobacterial organisms.

Fine needle aspiration cytology of suspected tuberculous lymphadenitis.

Fine needle aspiration cytology of suspected tuberculous lymphadenitis The aims of this cross-sectional study were to describe the distributional patterns of tuberculous lymphadenitis and to assess the correlation between fine needle aspiration cytology (FNAC) and the Ziehl Neelsen staining technique in diagnosing tuberculous lymphadenitis. Romanowsky's method (Wright's stain) for cytological diagnosis and Ziehl Neelsen (hot method) for the identification of acid-fast bacilli were utilized. Out of one hundred and twenty-eight consecutive patients attending the cytological diagnostic service of the Department of Pathology within Jimma University, 89 (69.6%) of the patients were younger than 30 years of age. The male to female ratio was 1.3 : 1. The cervical region was the most common site and involved 95 cases (74.2%), followed by the axillary and inguinal lymph node regions (20.3% and 4.3%, respectively). The Wright's-stained cytology smears were grouped into three categories: epithelioid granulomas without necrosis, epithelioid granulomas with caseous necrosis and necrosis without epithelioid granulomas. The Ziehl Neelsen stains were undertaken on separate slides: 20.0% of the cases showing epithelioid granulomas without necrosis, 61.9% of those with epithelioid granulomas with necrosis/abscesses and 69.7% of those with necrosis without granulomas were found to be positive for acid-fast bacilli. The overall positivity for the ZiehlNeelsen stained cases was 59.4%. It can therefore be concluded that FNAC is a reliable diagnostic tool in helping to avert the more invasive surgical procedures undertaken in the diagnosis of tuberculous adenitis. The ZiehlNeelsen stain for identification of acid-fast bacilli should be incorporated as an adjunct to increase the diagnostic accuracy of tuberculous lymphadenitis.

Mycobacterial cervical lymphadenitis in children: clinical and laboratory factors of importance for differential diagnosis.

The role of epidemiological and clinical features for the early differential diagnosis between Mycobacterium tuberculosis (MTB) complex and non-tuberculous mycobacterial (NTM) cervical lymphadenitis in children was examined in this study. From 1982 to 1997, 24 MTB complex cases and 26 NTM cases were diagnosed, of which 75% and 25%, respectively, presented during the first half of the study period. Epidemiological and lymph-node features and anatomical areas were not helpful in the differential diagnosis between the 2 groups. Fulfilment of 2 out of 3 criteria (positive tuberculin skin test reaction, abnormal chest radiograph, contact with a person with infectious tuberculosis) was associated with 92% sensitivity for the diagnosis of MTB lymphadenitis. 37.5% of the MTB cases and 88.5% of the NTM cases were culture-confirmed; all inconclusive cultures concerned patients with spontaneous drainage and fistula. Surgical intervention was required in 67% of the MTB cases. All NTM cases were managed by surgery alone. Fistulae or cheloids occurred in all patients in whom incision and drainage were applied instead of total excision. Excellent aesthetic results were achieved in patients who presented within 1 month following the onset of lymphadenitis. The spectrum of mycobacterial cervical lymphadenitis in children in Greece has changed during the 1990s. Early and prompt treatment contributes to the diagnosis and response.

The value of wide-needle aspiration in the diagnosis of tuberculous lymphadenitis in Africa.

OBJECTIVES: To evaluate wide-needle (19-gauge) aspiration in the diagnosis of tuberculous lymphadenitis. SETTING: Department of Surgery, University Teaching Hospital, Lusaka, Zambia. PATIENTS: Three hundred and four patients presenting to one surgeon for diagnostic surgical biopsy of a peripheral lymph node during 1989-1990. DESIGN: Prospective study in which wide-needle aspiration routinely preceded open surgical biopsy. MAIN OUTCOME MEASURES: Histology and mycobacterial culture of the surgically biopsied lymph node; HIV-1 serology; successful aspiration of material, naked-eye appearance of aspirate, presence of acid-fast bacilli and/or microscopic caseation in the aspirate. RESULTS: One hundred and eighty-eight out of 304 (61.8%) patients had histologically and/or culture-proven tuberculous lymphadenitis, of whom 155 out of 183 (84.7%) tested HIV-1-seropositive. Material was successfully aspirated from 180 out of 188 (95.7%) of patients with proven tuberculous lymphadenitis. Macroscopic caseation, diagnosable on naked-eye examination alone of the aspirate, was present in 49 out of 120 (40.8%) consecutive aspirates from tuberculous nodes. Acid-fast bacilli and/or microscopic caseation were seen in 116 out of 155 (74.8%) aspirates from tuberculous nodes for which smears stained both by Ziehl-Nielsen and haematoxylin & eosin were available. CONCLUSIONS: It is recommended that all patients with suspected tuberculous lymphadenitis in Africa, undergo wide-needle aspiration before surgical biopsy or empirical treatment.

Mycobacterial lymphadenitis in eastern Sydney.

BACKGROUND: There has been a resurgence of tuberculosis (TB) in the developed world, especially extrapulmonary manifestations, of which lymphadenitis is the most common. We reviewed all cases of mycobacterial lymphadenitis notified in the eastern suburbs of Sydney from 1989 to 1996. AIMS: To review all cases of mycobacterial adenitis in eastern Sydney. METHODS: This was a retrospective review of the medical records of 54 patients (aged 1.2 to 84 years), recruited from all notifications of TB presenting as lymphadenitis at Prince of Wales, Sydney Children's and St Vincent's Hospitals. RESULTS: There were two distinct groups: Group 1, patients with Mycobacterium tuberculosis (MTB), n = 37 (68.5%), Group 2, patients with atypical mycobacteria, n = 17 (31.5%). For Group 1, 83.3% were foreign born and 18.9% were positive for the human immunodeficiency virus (HIV). Disease involved single node groups in 73% (the cervical chain was involved in 70.1%). Complete resolution of lymphadenopathy at conclusion of treatment occurred in 73.1%. Outcome was not documented in 13.5%, of the rest; 83.8% completed treatment; 2.7% were lost to follow up before treatment concluded; 2.7% were still being seen at the time of writing and 10.8% died within six months of treatment starting (all were HIV positive). HIV positive patients had more diffuse disease. Group 2 were all Australian born. They comprised children less than six years who were all HIV negative and adults (aged 30-55 years) who were all HIV positive. The children were all treated surgically with 80% having complete resolution of their modes. Those adults with HIV had a mortality of 83.3% during treatment. CONCLUSIONS: In eastern Sydney lymphadenitis caused by MTB in the HIV negative population is mostly seen in those who are immigrants. Our large proportion of HIV positive patients tended to have diffuse disease and a high mortality. The reporting of outcomes was poor and in a greater than expected number of outcome and follow up were inadequately documented.

Bacteriological survey of tuberculous lymphadenitis in southeast England, 1981-1989.

STUDY OBJECTIVE: The aim was to detect any changing trends in the nature and incidence of tuberculous lymphadenitis in southeast England and to determine whether there is any evidence for an increase in this disease that could be related to HIV infection. DESIGN: Mycobacteria isolated from patients with lymphadenitis in the years 1981 to 1989 were identified. Information was available on the age, sex, and ethnic origin of the patients and the anatomical site from which the mycobacterium was isolated. SETTING: The Public Health Laboratory Service Regional Tuberculosis Centre at Dulwich, which receives over 95% of mycobacteria isolated in southeast England. MAIN RESULTS: From 1980 to 1989, cultures were received from 1817 patients with mycobacterial lymphadenitis: 1677 were M tuberculosis, 25 M bovis, 21 M africanum, and 94 were other (environmental) species. In comparison with a survey conducted in the same region in 1973-80, the number of ethnic Indian subcontinent patients with lymphadenitis due to M tuberculosis had dropped by 30% and the number of European patients had dropped by 43% and showed a continuing decline and a shift towards an older age group. By contrast, there was a 20% increase in the number of cases due to environmental mycobacteria. The number of species causing such infections had increased and a greater proportion of patients were adults. Three patients infected by environmental mycobacteria were known to be HIV positive. CONCLUSIONS: The incidence of lymphadentis due to M tuberculosis is declining but cases due to environmental mycobacteria are increasing, with a greater diversity of species and more adult patients. There is no conclusive evidence for an impact of HIV infection on the incidence and nature of mycobacterial lymphadenopathy in southeast England, but this cannot be ruled out.

Mycobacterial cervical lymphadenitis.

Cervical lymphadenitis is the most common head and neck manifestation of mycobacterial infections. The incidence of mycobacterial cervical lymphadenitis has increased. It may be the manifestation of a systemic tuberculous disease or a unique clinical entity localized to neck. It remains a diagnostic and therapeutic challenge because it mimics other pathologic processes and yields inconsistent physical and laboratory findings. A high index of suspicion is needed for the diagnosis of mycobacterial cervical lymphadenitis. A unilateral single or multiple painless lump, mostly located in posterior cervical or supraclavicular region can occur. A thorough history and physical examination, tuberculin test, staining for acid-fast bacilli, radiologic examination, fine-needle aspiration and PCR will be instrumental in arriving at an early diagnosis early institution of treatment before a final diagnosis can be made by biopsy and culture. It is important to differentiate tuberculous from nontuberculous mycobacterial cervical lymphadenitis because their treatment protocols are different. Tuberculous adenitis is best treated as a systemic disease with antituberculosis medication. Atypical infections can be addressed as local infections and are amenable to surgical therapy.

Shortening the duration of treatment for cervical tuberculous lymphadenitis.

The aim of the study was to determine the optimal duration of treatment for patients with tuberculous lymphadenitis. The Medline database was searched for relevant articles published between 1978-1997. Inclusion criteria were study populations of patients with predominantly cervical tuberculous lymphadenitis in whom the diagnosis had been confirmed bacteriologically and/or histologically, or was made probable by using clinical and laboratory markers. Treatment management had to include at least isoniazid, rifampicin and pyrazinamide and a follow-up of at least 12 months after the end of treatment. Patients with resistance to rifampicin and pyrazinamide and previous treatment for tuberculosis were excluded. The number of patients who relapsed after treatment was calculated. The study population in eight out of the 35 articles retrieved were suitable for analysis. Some concerned comparative studies. There were eight treatment schedules of 6 months' duration and three schedules of 9 months' duration. Treatment for 6 months resulted in a tuberculous lymphadenitis relapse rate of 13/422=3.3% (95% confidence interval: 1.7-5.5), with a mean follow-up of 31 months after completion of treatment. Treatment for 9 months resulted in a relapse rate of 3/112=2.7% (95% confidence interval: 0.6-7.8), with a mean follow-up of 20 months. Despite the limitations of the literature available, 6 months of therapy is probably sufficient for patients with tuberculous lymphadenitis.

Mediastinal tuberculous lymphadenitis: MR imaging appearance with clinicopathologic correlation.

OBJECTIVE: The purpose of our study was to determine the MR imaging appearance of mediastinal tuberculous lymphadenitis and to compare these findings with clinical and pathologic findings. MATERIALS AND METHODS: MR images of 23 consecutive patients with mediastinal tuberculous lymphadenitis were retrospectively analyzed with regard to homogeneity, signal intensity, and enhancement of diseased nodes after injection of contrast material (n = 19), and the imaging findings were grouped by patterns and correlated with clinical signs or symptoms and with pathologic (n = 9) findings. RESULTS: Three imaging patterns of mediastinal tuberculous lymphadenitis (113 nodes) were seen of MR images. In six patients, nodes (type 1, n = 25) were relatively homogeneous and hyperintense to muscle on both T1- and T2-weighted images and enhanced homogeneously after injection of contrast material. The patients had mild (n = 2) or no (n = 4) constitutional symptoms. The nodes corresponded pathologically to tuberculous granulomas without or with minimal necrosis. In 14 patients, nodes (type 2, n = 71) were inhomogeneous with a strong peripheral enhancement after injection of contrast material. Enhancing areas were of intermediate intensity on T1-weighted images and hypointense on T2-weighted images, and corresponded pathologically to peripheral granulation tissue within the nodes. Unenhanced areas were relatively hypointense on T1-weighted images and markedly hyperintense on T2-weighted images, and corresponded pathologically to central caseation or liquefaction necrosis within the nodes. All but one patient with type 2 nodes had moderate to severe clinical signs and symptoms. In the remaining three patients, nodes (type 3, n = 17) were homogeneously hypointense on both T1- and T2-weighted images and did not enhance after injection of contrast material. No patient with type 3 nodes had clinical signs or symptoms. The nodes corresponded pathologically to fibrocalcified nodes. CONCLUSION: The most common MR imaging appearance of mediastinal tuberculous lymphadenitis was as inhomogeneous nodes with marked hyperintensity on T2-weighted images and peripheral enhancement after injection of contrast material. This typical MR imaging appearance was mostly seen in severely symptomatic patients and was due to caseation necrosis of the tuberculous nodes.

[Rational diagnostic strategy for tuberculous lymphadenitis] .

OBJECTIVES: To examine the clinical, radiographic and laboratory findings in patients with tuberculous lymphadenitis and to analyse the investigational strategies which lead to the diagnosis of tuberculous lymphadenitis. METHODS: Retrospective study including 16 HIV-negative patients at the Cantonal Hospital, Winterthur with tuberculous lymphadenitis diagnosed between 1994 and 1999. RESULTS: The majority of patients presented with local symptoms and without signs of severe systemic disease. All the PPD skin tests performed were positive. Cultures for M. tuberculosis were more often positive using fine-needle aspiration than surgical biopsy. We found a lack of systematic diagnostic strategy. CONCLUSIONS: We suggest a standardised investigation procedure. When tuberculous lymphadenitis is suspected, the first diagnostic step consists of a PPD skin test and fine-needle aspiration for acid fast smear, mycobacterial culture and cytology. Surgical biopsy should be done if the cytological and mycobacteriological results of fine-needle aspiration are not diagnostic.

Mycobacterial cervical lymphadenitis in childhood.

A study of 190 children of chronic cervical lymphadenitis showed tuberculous etiology on histopathological examination in 92 (48.4%) and bacteriological evidence of mycobacterial infection (smear and/or culture) in 42 (22.1%). Of these 42, twelve (28.6%) showed histopathological diagnosis of non-specific lymphadenitis. Positive culture for mycobacteria was obtained in 40, of which 30 (75%) were typical M. tuberculosis and 10 (25%) were atypical mycobacteria. The most predominant species of typical mycobacteria was M. scrofulaceum (60%) followed by M. avium intracellulare (40%). There was no remarkable difference in the histopathological pattern of those in which M. tuberculosis was grown and those in which bacterial growth was that of atypical mycobacteria. The diagnosis of chronic cervical lymphadenitis should therefore be taken a step beyond histopathology, up to complete bacteriological examination, especially to confirm the cases of mycobacterial lymphadenitis caused by atypical mycobacteria.

Diagnosis of tuberculosis lymphadenitis using a polymerase chain reaction on peripheral blood mononuclear cells.

Providing prompt and precise laboratory confirmation of a clinical diagnosis of tuberculous lymphadenitis is difficult given the paucibacillary nature of lymph node specimens. In this study carried out in Karachi, Pakistan, a polymerase chain reaction (PCR) assay aimed at detecting Mycobacterium tuberculosis DNA in peripheral blood mononuclear cells (PBMC-PCR) was standardized and compared with standard M. tuberculosis diagnostic techniques or a lymph node PCR (LN-PCR) for the diagnosis of tuberculosis lymphadenitis. Thirty-seven (77%) specimens from 48 patients with clinical or diagnosis of tuberculosis lymphadenitis were positive by cytology [17/48 (35%) with no acid fast bacilli (AFB) (suggestive), and 20/48 (42%) with AFB (positive) in direct smears], 30 (63%) by PBMC-PCR, 16 (33%) by LN-PCR, and 13 (27%) by culture. All controls were negative, with the exception of one false-positive LN-PCR. These data suggest the PBMC-PCR may be helpful in the diagnosis of tuberculous lymphadenitis.

[Diagnosis of tuberculous lymphadenitis based on the fine needle aspiration samples analysis].

Tuberculous lymphadenitis is one of the most common extrapulmonary manifestations of tuberculosis. The most common lymph nodes involved are in the cervical region. Lymphadenitis due to M. tuberculosis generally presents with enlarging neck lymph nodes over weeks or months associated with fever, weight loss and fatigue. Fine needle aspiration (FNA) of affected lymph nodes has been shown to yield a high sensitivity and specificity in the diagnosis of tuberculous lymphadenitis. Specimens should be examined cytologically, as well as by AFB smear and cultures. The time between the onset of symptoms, clinical presentation and final diagnosis is often too long. We present a case of 60 years old man with tuberculous lymphadenitis, initially suspected of lymphoproliferative disease.
