Mycosis on mycosis fungoides: zoophilic dermatophytosis selectively superimposed on pre-existing cutaneous T-cell lymphoma (mycosis fungoides) plaques.

We report a case of tinea corporis caused by a cattle-derived strain of Trichophyton mentagrophytes in a 44-year-old male affected by cutaneous T-cell lymphoma (CTCL, so-called mycosis fungoides). Fungal colonization of glabrous skin was strictly confined within pre-existing lymphomatous plaques. Either oral itraconazole or griseofulvin, or topical terbinafine were ineffective until the patient, who was treated with systemic retinoids and interferon-alpha for his CTCL, was shifted from leucocyte to lymphoblastoid interferon. The hypothesis that a local immunodisturbance could be responsible for the selective superimposition of tinea on CTCL lesions ('mycosis on mycosis'), and that such an immunodisturbance could be partially corrected by the interferon switch is discussed.

[Clinical features of deep mycosis in critical care center--comparison of serological tests and cultures for mycosis].

The clinical features of invasive deep mycosis in the critical care center was studied and the usefulness for determinations of plasma (1-->3)-beta-D-glucan, one of the major structural components of fungi, in making the diagnosis of deep mycosis was evaluated in comparison with that of blood culture and candida antigen titer using CAND-tec kit. A total of 92 febrile patients (mean age = 54.5 yr., M/F = 70/22) in our critical care center were enrolled in this study. Seventeen out of the 92 febrile patients (18.5%) were those with deep mycosis. In the deep mycosis group, there were 10 patients with fungal panperitonitis, 5 with fungaemia, one with candidal pneumonia and one with candidal empyema. A total of 52 blood samples were obtained from 17 patients with deep mycosis. Forty five out of the 52 blood samples (86.5%) were positive for serum (1-->3)-beta-D-glucan while only 10 were culture-positive. In contrast, six (15.0%) out of the 40 blood samples were obtained from 17 patients with deep mycosis were positive for candida antigen by CAND-tec kit. In the critical care center, deep mycosis is a common infection and determination of serum concentration of (1-->3)-beta-D-glucan is found to be a very useful examination in screening of deep mycosis with high sensitivity and specificity.

"Hypopigmented mycosis fungoides" is not always mycosis fungoides!

We conducted a critical review of hypopigmented mycosis fungoides in historical perspective with emphasis on criteria clinical and histopathologic for diagnosis of that lymphoma as they are set forth in every article ever written about it. Toward that end, we undertook analysis of each article in the medical literature that mentioned hypopigmentation in mycosis fungoides (34 in toto). Each was scrutinized regarding content, photographs of lesions clinical pictured, and photomicrographs. On the basis of all the information in the 34 publications available to us, we made a determination about which patients had mycosis fungoides without doubt, which surely did not, and which about whom no judgment could be made by us because too little data requisite for such a decision was provided, especially in terms of photographs of lesions clinical and of photomicrographs. To date, 106 patients with "hypopigmented mycosis fungoides" have been reported on. Features clinical and findings histopathologic in 23 of those 106 patients were sufficient to permit us to determine, with a high degree of confidence, whether or not a particular patient truly had mycosis fungoides. In our judgment, 19 patients did have mycosis fungoides, whereas at least four patients did not. In regard to the other 83 patients, the information provided by the authors simply was not sufficient to allow us to come to a decision that we could justify.

Interstitial mycosis fungoides, a variant of mycosis fungoides resembling granuloma annulare and inflammatory morphea.

BACKGROUND: Interstitial mycosis fungoides (IMF) is a rare variant of mycosis fungoides that resembles the interstitial form of granuloma annulare and inflammatory morphea. IMF has received little attention in the literature. METHODS: Clinical, histological, immunophenotypical, and genotypical findings of five cases of IMF were reviewed. The histological and immunophenotypical findings were compared with those of eight cases of interstitial granuloma annulare and six cases of inflammatory morphea. RESULTS: Five patients with IMF presented with non-indurated, erythematous macules; ill-defined erythematous plaques with slight scale; and nodules on the trunk and proximal limbs. Two of five patients had a prior diagnosis of mycosis fungoides. Skin biopsies revealed a striking dermal interstitial infiltrate of lymphocytes with rare histiocytes that resembled the interstitial form of granuloma annulare or inflammatory morphea. Epidermotropic lymphocytes were present at least focally in all cases. A band-like lymphocytic infiltrate was observed in two of five cases. In contrast, many plasma cells and histiocytes were observed in cases of inflammatory morphea and interstitial granuloma annulare, respectively. With Movat-pentachrome stains, increased dermal mucin deposition was observed in two of five IMF cases, in all cases of interstitial granuloma annulare, and in one of six cases of inflammatory morphea. There was focal loss of elastic fibers in all cases of inflammatory morphea. Immunohistochemical studies of IMF highlighted a dominant population of T cells (CD3+) in the dermis and epidermis. In contrast, moderate numbers of B cells (CD20+) were admixed with T cells and plasma cells in inflammatory morphea. Almost equal numbers of histiocytes (CD68+) and T cells comprised the infiltrate of interstitial granuloma annulare. In two of five IMF cases, a clonal T-cell population was detected by PCR T-cell gamma gene rearrangement analysis. CONCLUSION: Mycosis fungoides occasionally presents as an interstitial lymphocytic infiltrate that mimics granuloma annulare and inflammatory morphea. Hematoxylin & eosin (H&E) findings alone can sometimes distinguish the three disorders. Immunophenotyping and genotyping may be helpful in difficult cases.

An unusual case of mycosis fungoides presenting as sarcoidosis or granulomatous mycosis fungoides.

The authors describe a case of cutaneous and lymph node granulomas first reported as sarcoidosis. As skin sarcoidlike reactions disappeared, the development of typical histologic and immunopathologic features of cutaneous mycosis fungoides suggested granulomatous mycosis fungoides. This case illustrates the difficulties in differentiating true systemic sarcoidosis associated with mycosis fungoides from sarcoidlike reactions when extensive granulomas obscure the underlying cutaneous lymphoma. This report emphasizes the utility of immunohistochemical analysis to identify the early cutaneous T-lymphomatous infiltrate, initially admixed with epithelioid and giant cell granulomas. This technique also made it possible to characterize a Ki-1-positive anaplastic large-cell lymphoma when the transformation of mycosis fungoides into highly malignant lymphoma occurred in the lymph node.

Pagetoid reticulosis, epidermotropic mycosis fungoides and mycosis fungoides: a disease spectrum.

Using a standard technique involving monoclonal antibodies against T-cell subsets, we have shown that almost all the infiltrating T-cells in the epidermis of a patient with Pagetoid reticulosis (PR), one with epidermotropic mycosis fungoides (EMF) and one with poikiloderma atrophicans vasculare (PAV), were OKT8 positive (presumed cytotoxic/suppressor) T-cells. The infiltrating T-cells in the epidermis of a patient with limited plaque stage mycosis fungoides (MF), however, were almost exclusively Leu 3a-positive (presumed helper/inducer) T-cells as is usually found in this condition. The keratinocytes in the patients with PR, EMF and PAV were HLA-DR-positive whilst those in the patient with MF were HLA-DR-negative. We consider these four diseases to be part of the spectrum of mycosis fungoides, the first three conditions representing the early or benign end of the spectrum.

13-cis-retinoic acid effective in mycosis fungoides. A report from the Scandinavian Mycosis Fungoides Group.

Twenty patients with mycosis fungoides and four with Sézary's syndrome were treated with 13-cis-retinoic acid as single therapy in an initial dose of 1 to 2 mg per kg body weight in most cases. Complete remission in mycosis fungoides was obtained in six cases (33%) and partial remission in another ten cases (50%). No convincing response was observed in three cases, and progression of limited nodular lesions occurred in one case. In cases responding to treatment the first sign of remission was observed within two to four weeks. Our short-term experience is that the drug is effective in early as well as advanced stages of mycosis fungoides. Patients with Sézary's syndrome, however, did not respond to the same extent.

Retinoids and systemic chemotherapy in cases of advanced mycosis fungoides. A report from the Scandinavian Mycosis Fungoides Group.

In cases of advance mycosis fungoides, the systemic chemotherapy combination of bleomycin, cyclophosphamide and prednisolone was given to 8 cases, and the same 3-drug combination with the addition of oral retinoids given to 12 cases. All cases were in a progressive phase of the disease. Remission was obtained in 5/8 cases treated with the combination and in 7/12 cases treated with the combination plus retinoids. The remissions were complete in half of the cases, but relapse occurred within 3 to 6 months in all but 2 cases. The two treatment patient groups were not fully comparable but the conclusion is that the addition of retinoids to systemic chemotherapy combination regimens is of some advantage. There still exists, however, need of more adequate treatment modalities in advanced mycosis fungoides.

Oral retinoids in mycosis fungoides and Sézary syndrome: a comparison of isotretinoin and etretinate. A study from the Scandinavian Mycosis Fungoides Group.

Thirty-nine patients with mycosis fungoides in various stages or Sézary syndrome were treated with isotretinoin and 29 with etretinate as single drug therapy. Complete remission within 2 months was obtained with isotretinoin in 8 cases (21%) and partial remission in another 15 cases (38%). Etretinate induced complete remission in 5 cases (21%) and partial remission in 11 (46%). Only 1 case with Sézary syndrome went into partial remission. The first sign of remission occurred in 2 to 4 weeks. During continued treatment remissions could not always be maintained. Isotretinoin and etretinate were considered to be of equal potency in the treatment of mycosis fungoides.

Aspects of the treatment of mycosis fungoides. A report from the Scandinavian Mycosis Fungoides Study Group.

The Scandinavian Mycosis Fungoides Study Group includes dermatologic clinics in Denmark, Norway, and Sweden. The results of the first three years of activity are presented herein. In plaque stage, topical nitrogen mustard was highly effective. Preceding intravenous tolerance induction seems to be of no value. PUVA induced equally high remission rates. Both modalities were also highly effective in cutaneous tumor stage. In advanced tumor stage and in case of extracutaneous involvement systemic chemotherapy was given. Topical treatment alone was more effective on the cutaneous lesions including tumors than systemic chemotherapy alone. Therefore a combination of topical and systemic treatment is recommended in advanced stages of mycosis fungoides.

Combination chemotherapy in the tumour stage of mycosis fungoides with cyclophosphamide, vincristine, vp-16, adriamycin and prednisolone (cop, chop, cavop): a report from the Scandinavian mycosis fungoides study group.

Combination chemotherapy with cyclophosphamide, vincristine, VP-16, adriamycin and prednisolone was given in 9 cases of mycosis fungoides in the tumor stage; 3 of these patients received COP, one received CHOP, and 5 CAVOP. Complete remission was obtained in one case and partial remission in 5, the response rate thus being 6/9. It was impossible, however, to maintain remission. The treatment was reduced or withdrawn owing to toxic effects in 4 cases. These forms of combination chemotherapy are beneficial in non-Hodgkin lymphomas but do not seem to be of value in the tumour stage of mycosis fungoides.

Tumour stage of mycosis fungoides treated with bleomycin and methotrexate: report from the Scandinavian mycosis fungoides study group.

The Scandinavian Mycosis Fungoides Study Group have treated 19 patients with mycosis fungoides in tumour stage by systemic chemotherapy. Nine patients were treated with Bleomycin 15 mg i.m. twice weekly for 7 weeks and 10 patients with the same dose of Bleomycin in combination with Methotrexate 15 mg i.m. per m2 body surface each week for 7 weeks. No maintenance treatment was given. The immediate therapeutic effect of Bleomycin alone was considered good in half of the patients. Bleomycin and Methotrexate together produced a better initial effect. In both treatment series the remission was short-lived in the absence of maintenance therapy. The mortality rate was high, especially in combination treatment. Lethal complications occurred in 6 patients during the treatment, 3 of which were thromboembolic, one pancytopenia, one lung fibrosis with pulmonary insufficiency, and one bronchopneumonia. The conclusion is that these two forms of therapy cannot be recommended.

Mycosis fungoides plaque stage treated with topical nitrogen mustard with and without attempts at tolerance induction: report from the Scandinavian mycosis fungoides study group.

The Scandinavian Mycosis Fungoides Study Group has treated 21 patients with mycosis fungoides in plaque stages with topical, whole-body application of nitrogen mustard, 20 mg in 40 ml water per square metre. Ten patients were treated after previous attempts at intravenous tolerance induction ad modum van Scott & Kalmanson and eleven without. Complete remission was initially achieved in 10 patients and partial remission in 9 patients. Contact dermatitis to nitrogen mustard developed in 2/10 after tolerance induction and in 1/11 without tolerance induction. It is concluded that topical, whole-body application of nitrogen mustard gives high remission rates. In this series, however, many relapses occurred, due to inadequacy of the maintenance treatment. Tolerance induction has not been found of any value.

Prophylactic and therapeutic effects of oral administration of amphotericin B in mycosis associated with hematologic diseases. Study Group of Mycosis in Hematologic Disease.

The prophylactic and therapeutic effects of the oral administration of amphotericin B (AMPH) to patients with deep mycosis associated with hematologic diseases were evaluated in an investigation including determination of serum concentrations of the antibiotic. Prophylactic effects were examined in 111 subjects, and the efficacy rates averaged 83.8% at daily doses from 1,200 to 4,800 mg. The efficacy was significantly higher at a dose of 2,400 mg/day than at a dose of 1,200 mg/day (P less than 0.05). The efficacy rate tended to be higher when the length of administration period was 1 month or more. The percentage of the number of days of fever by neutrophil count was significantly less at a daily dose of 2,400 mg than at 1,200 mg in patients with neutrophil count of 1,000 cells/mm3 or less (P less than 0.001). The safety was evaluated in 131 subjects, and adverse effects were found in only 2 cases of nausea for an incidence rate of 1.5%. Therapeutic effects were studied in 12 cases, and efficacy rates averaged 58.3% at daily doses from 2,400 to 7,200 mg. Adverse effects consisted of 1 case of diarrhea among 15 subjects who were evaluated for the safety for an incidence rate of 6.7%. The serum concentrations of the antibiotic were examined in 60 of the prophylactic and therapeutic subjects. Average concentrations of AMPH at 4 hours after the first daily dose of 1,200, 2,400 and 4,800 mg were 0.040, 0.053 and 0.078 micrograms/ml, respectively. Concentrations gradually increased thereafter and reached averages of 0.089, 0.090 and 0.132 micrograms/ml, respectively, for the 3 dose levels on the 7th day. These results indicated that there were no serious adverse effects and serum concentrations were above the Candida MIC values at daily prophylactic and therapeutic doses of 1,200 to 7,200 mg of AMPH. Based on these findings, this drug can be expected to show prophylactic and therapeutic effects with safety in cases of deep mycosis.

Papular mycosis fungoides: a new clinical variant of early mycosis fungoides.

BACKGROUND: Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma. In early stages of the disease many different clinicopathologic variants have been observed. OBSERVATION: We report 6 patients with early manifestations of MF characterized by the sole presence of papules which, unlike the papules of lymphomatoid papulosis, did not show a tendency for spontaneous resolution. Histologic examination confirmed the diagnosis of MF in all cases. Immunohistochemical staining for CD30 was negative in all cases. Follow-up data showed the nonaggressive behavior of the disease, confirming that the lesions were not manifestations of advanced MF. CONCLUSION: Papular MF is a new variant of early MF characterized by the presence of papules in the absence of more conventional early lesions (patches) of the disease. This variant should be added to the long list of clinicopathologic subtypes of MF.

Thymus and activation-regulated chemokine (TARC/CCL17) in mycosis fungoides: serum TARC levels reflect the disease activity of mycosis fungoides.

BACKGROUND: Mycosis fungoides (MF) belongs to cutaneous T-cell lymphoma and is clinically divided into 3 stages: patch, plaque, and tumor stage. Thymus and activation-regulated chemokine (TARC/CCL17) is a member of the CC chemokines and is a chemoattractant for CC chemokine receptor 4 (CCR4)- and CC chemokine receptor 8 (CCR8)-expressing cells. OBJECTIVE: In this study, we examined the involvement of TARC among patients with each stage of MF. METHODS: We investigated the expression of TARC, CCR4, and CXC chemokine receptor 3 in patients with each stage of MF by immunohistochemistry. We measured serum TARC levels in 20 patients with MF in varying degrees and compared them with 10 patients with psoriasis vulgaris and 10 healthy controls. In addition, we compared serum TARC levels in patients with MF with other laboratory data. RESULTS: Immunohistochemical staining revealed that TARC was expressed in the lesional keratinocytes in the patch, plaque, and tumor stages. CCR4 was expressed on the epidermotropic cells in both patch and plaque stages and on the large cell-transformed cells in the tumor stage, whereas CXC chemokine receptor 3 was constantly expressed on the small cells in the lesional dermis. Serum TARC levels in patients with MF were significantly higher than those in patients with psoriasis vulgaris or healthy controls. Moreover, serum TARC levels in patients with the tumor stage of MF (n = 5) were remarkably higher than those with patch stage (n = 8) or plaque stage (n = 7). Serum TARC levels significantly correlated with serum lactate dehydrogenase levels (r = 0.62), serum immunoglobulin E levels (r = 0.60), serum soluble interleukin 2 receptor levels (r = 0.72), and serum macrophage-derived chemokine levels (r = 0.70). CONCLUSION: These data strongly indicate that serum TARC levels are useful for assessing the disease activity of patients with MF and that TARC and CCR4 may be involved in the pathogenesis of MF.
