Total scalp treatment of mycosis fungoides: the 4 x 4 technique.

PURPOSE: A technique for treating mycosis fungoides confined to the scalp using a method known as the 4 x 4 technique is presented. METHODS AND MATERIALS: Uniform dose distribution on the scalp and acceptable "hot spots" along five match lines is accomplished by using four sets of four fields (i.e., 4 x 4) on the patient. Precise and reproducible patient and field alignment was accomplished with a solid thermoplastic mask, which is the surface on which match lines are drawn. In-vivo dosimetry (thermoluminescent dosimeters and film) are easily attached to the mask which also provides a portion of the 7 mm bolus used to shift the characteristic 6 MeV electron depth dose toward the skin surface. RESULTS: In-vivo dosimetry demonstrated that single fraction match line doses are within 25% to 30% of central axis dose. Shifting these match lines to four locations reduces these "hot spots" to satisfactory levels (less than 120%). Three patients have been treated with this technique and each patient continues to have a complete clinical response at 14 to 21 months post treatment. In addition, each patient has excellent cosmetic results with no evidence of acute or chronic side effects at the match lines. CONCLUSION: The 4 x 4 technique has proven to be useful in the treatment of mycosis fungoides confined to the scalp.

Lymphocyte transformation in patients with staged mycosis fungoides and Sézary syndrome.

Lymphocyte transformation was studied in patients with mycosis fungoides and the Sézary syndrome with particular reference to the stage of disease. Phytohemagglutinin-induced lymphocyte blastogenesis was normal in stage II, became depressed in stage III and was greatly reduced in stage IV disease. Similar abnormalities were found in patients with the Sézary syndrome once the proportion of abnormal cells in the peripheral blood exceeded 10%. It is concluded that stag III mycosis fungoides is probably a critical period in determining dissemination of the disease.

Mycosis fungoides d'emblée: a rare presentation of cutaneous T-cell lymphoma.

A case of the d'emblée variant of mycosis fungoides is presented to confirm the validity of this rare variant of cutaneous T-cell lymphoma. The patient had rapidly progressing cutaneous tumors of mycosis fungoides with no internal organ or nodal involvement at the onset of the disease. This was confirmed at a laparotomy, which was done to remove a uterine leiomyoma. The classic light microscopy was confirmed by electron microscopy. Postmortem findings showed a remarkable degree of "epitheliotropism." The d'emblée form of mycosis fungoides has been disputed by some who argue that these cases represent a lymphoma that begins elsewhere and has secondary skin involvement. In this patient there was an opportunity, within a few weeks of the onset of the problem, to do an extensive staging work-up, including laparotomy. No evidence of internal lymphoma was found.

Granulomatous mycosis fungoides: report of a case with some histopathologic features of granulomatous slack skin.

We describe a case of granulomatous mycosis fungoides, tumor stage, mimicking sarcoidosis in an 82-year-old man with a 2-year history of skin disease. The final diagnosis was established after one of seven biopsy specimens showed a nongranulomatous histologic picture of patch-stage mycosis fungoides. Monoclonality was proven for the lymphocytic population by T-cell-receptor rearrangement studies. The unusually extensive granulomatous inflammation with huge giant cells surrounded by CD1a-positive cells in the other six biopsy specimens was suggestive of the histopathology of granulomatous slack skin, another rare granulomatous cutaneous T-cell lymphoma. Because both a clinical and histologic overlap between granulomatous mycosis fungoides and granulomatous slack skin have been reported in the literature, we conclude that they may belong to the spectrum of a single disease.

Photochemotherapy in mycosis fungoides. A study of 73 patients.

Seventy-three patients with mycosis fungoides were treated with photochemotherapy and followed up for 2 to 39 months. Photochemotherapy produced clinical and histological clearing in a very high proportion of patients with stage 0 to II disease. The response in patients with tumours was less satisfactory, and a high proportion of these patients required local radiotherapy to resistant lesions. Maintenance treatment with photochemotherapy may keep many patients with stage 0 to II disease in remission for up to 3 years, but patients with advanced disease may relapse despite maintenance treatment. Patients with all stages of mycosis fungoides may relapse when maintenance treatment is withdrawn.

Mycosis fungoides: an Australian experience.

Analysis was undertaken of 107 patients with mycosis fungoides who presented to St. Vincent's Hospital, Melbourne, during 1977-95. The mean age at diagnosis (55 years) was significantly older than the mean age of onset of symptoms (48 years). The mean duration of follow-up was 7.7 years. Urban residence was over-represented in this group of patients and in those with mycosis fungoides recorded at the State Cancer Registry. Eighty-four per cent were diagnosed at Stage I or II of the disease. Presentation with disease more advanced than Stage I was more likely to be found in males. Disease localized only to the trunk accounted for 45% of all patients. The mean number of biopsies prior to diagnosis was 1.4 but two-thirds were diagnosed at first biopsy. Almost 85% of patients had as their initial treatment either PUVA (44.9%), topical steroids (20.6%) or topical nitrogen mustard (18.7%) and 57% received only one or two treatment modalities during the period of the study. Stage at presentation was not related to the likelihood of clearance following treatment, recurrence, progression to a more advanced stage of disease or survival.

Are alcohol intake and smoking associated with mycosis fungoides? A European multicentre case-control study.

The incidence of mycosis fungoides (MF) is low, and the aetiology of the disease is unknown. The aim of this study was to investigate whether wine consumption protects against the disease and whether smoking constitutes a risk factor. This paper is part of the European Rare Cancers Study that tries to determine the risk factors for seven selective rare cancers, including mycosis fungoides, involved in the development of cancer. A multicentre case-control study was conducted in six European countries. Only incident cases with confirmed histology were included in the analysis which include a total of 76 cases of MF and 2899 controls. Wine intake had no protective effect; on the contrary the consumption of more than 24 g of alcohol per day was associated with a high risk of MF (odds ratio (OR)=3.02, 95% confidence interval (CI), 1.34-6.79), after adjusting for centre, country, age, sex and education. There was a dose-dependent increase in the risk of MF with increased smoking habits, albeit the observed trend was not statistically significant. A combined exposure to high tobacco and alcohol use yielded a significantly increased risk factor for MF (P=0.0073). Alcohol intake was associated with MF.

Transfer factor in mycosis fungoides: three years experience.

13 patients with clinically and histologically verified mycosis fungoides were treated with transfer factor as additional therapy to the hitherto conventional treatment after this had failed. After approximately 3 years, complete remission was present in 3 patients, 4 patients were significantly improved and registered as being in partial remission, while the condition was registered as no change in 3 patients. 1 patient was found worse, 1 patient had died after discontinuation of therapy and 1 patient was out of the study. In this case treatment was withdrawn because of the development of contact urticaria to nitrogen mustard, her basic therapy. The number of T lymphocytes, which was low prior to treatment, increased to normal values during the therapeutic period. During the first year a decrease in serum IgE was noted. The results of the clinical evaluation seem to indicate that transfer factor may be of value as an additional therapeutic agent in mycosis fungoides. Controlled investigations are needed and are in progress.

Rosette-formation with mouse erythrocytes: VI. T, B, and third population lymphoid cells in mycosis fungoides and effect of leukopheresis.

Peripheral blood from 16 patients with mycosis fungoides and two patients with Sézary syndrome was examined for T, B, and third-population (K) cells, using a battery of surface markers. T lymphocytes as determined by spontaneous rosette formation with sheep erythrocytes and third-population cells as determined by the Ripley rosette test were present in normal proportions. Surprisingly, B lymphocytes, as determined by surface immunoglobulin and receptors for mouse erythrocytes, were either lacking or were present in low proportions in some patients. Normal proportions were present in others. Repeat studies of two of three patients lacking B lymphocytes, following treatment, revealed normal or low proportions of B cells. Two patients with mycosis fungoides had increased proportions of "null" cells. Study of lymphoid cell subpopulations before and after leukopheresis in a single patient demonstrated a decrease in T cell proportions associated with a concomitant increase in the proportions of "null" cells following this therapy.

Southern blot analysis of clonal rearrangements of T-cell receptor gene in plaque lesion of mycosis fungoides.

T-cell populations of 22 plaque lesions from seven mycosis fungoides patients were studied for clonal rearrangement of the beta chain of the T-cell receptor (T beta) gene. All plaque lesions employed in this study showed clinically similar appearance. Histologically, all the biopsy specimens showed epidermotropism and the dermal infiltration of mononuclear cells including atypical cells. Histochemically, the majority of the infiltrated cells had surface markers of helper T cells. DNA extracted from skin lesions, peripheral lymphocytes, and lymph nodes revealed that the monoclonal expansion of T cells was different among patients and lesions. DNA extracted from the two skin lesions of case 1 revealed a clonal expansion of T cells. The rearranged bands persisted for about 1 year. In contrast, all lesions from cases 3-7 showed no rearranged band. Interestingly, three lesions from case 2 showed mixed type results, i.e., the monoclonal expansion of T cells was detected in one lesion but not in the other two lesions. Time course study of case 2 revealed that the same rearranged band became detectable in all three skin lesions and a lymph node about 1 year later. These results suggest that in plaque lesions of mycosis fungoides, there are various stages of detectable monoclonality of infiltrating cells, although the clinical appearance of the plaques was similar, and that the variety of monoclonality may reflect the long clinical course of this disease.

Ultraviolet-B phototherapy is successful in Japanese patients with early-stage mycosis fungoides.

UVB phototherapy is widely used for the treatment of psoriasis and atopic dermatitis, however, only limited reports evaluate its usefulness in the treatment of mycosis fungoides. We introduced UVB phototherapy to five patients with early-stage mycosis fungoides. All of them were classified as stage IB (erythematous stage), and none had obtained a satisfactory response to other therapies. After initial treatment with UVB phototherapy, all the patients obtained significant improvement in their skin lesions leaving pigmentary changes. After this satisfactory response was achieved, the same dose of UVB was administrated as a maintenance therapy with longer intervals between exposures. Histopathological examination of three patients revealed decreased numbers of inflammatory cells in both the epidermis and the dermis after the treatment. Immunohistochemical study showed that CD1a+/HLA-DR+ dendritic cells were present throughout the lesional epidermis before the treatment. In contrast, after the treatment, the dendritic cells in the epidermis were CD1a+/HLA-DR-. Although it remains unclear why only the expression of HLA-DR antigen was eliminated after treatment, we presume that this loss of HLA-DR antigen expression by epidermal Langerhans cells was, in part, responsible for the improvement of skin lesions. This preliminary study suggests that UVB phototherapy is an effective treatment for patients with early-stage mycosis fungoides.

[Association between mycosis fungoides and myasthenia gravis (author's transl)].

Myasthenia gravis characterized by physical examination, electrophysiologic abnormalities, ephedronium test, without thymoma, associated in a 47 year-old-man, with mycosis fungoides. Myasthenia gravis began two years after the onset of mycosis fungoides, and the patient died of infection four years after the development of the cutaneous lymphoma. At autopsy, there was no visceral involvement. Myasthenia gravis and lymphoma rarely coexist; the occurrence of myasthenia gravis shortly after the onset of mycosis fungoides suggests that the two disorders may be linked by immunological abnormalities.

Disseminated pagetoid reticulosis associated with mycosis fungoides: immunomorphologic study.

We report a 77-year-old woman with erythrosquamous plaques on the legs for 10 years. Biopsies taken 4 years ago revealed a pagetoid reticulosis with a massive epidermal cell infiltrate. She has now also developed a typical tumor of mycosis fungoides. The epidermal infiltrate of the two types of lesions bore the surface membrane marker for T lymphocytes rich in both T helper and T cytotoxic-suppressor subsets (ratio, 1.8). Both lesions also showed dendritic OKT6-positive Langerhans cells, and staining of the intercellular material with the DR locus of human lymphocyte antigen was positive. A dense dermal infiltrate was evident only in the mycosis fungoides lesions, and it was similar to that in the epidermis. Electron microscopy of the two lesions showed the atypical cells described in mycosis fungoides and the Sézary syndrome. These observations suggest that disseminated pagetoid reticulosis probably is a variant of mycosis fungoides.
