    ABSTRACT: Among the dematiaceous fungi responsible for human or animal phaeohyphomycosis, the Exophiala genus is a well-known etiologic agent and presently includes nine species considered as opportunist pathogens. To our knowledge, Exophiala spinifera has been reported as causative agent of only thirteen cases of cutaneous or systemic phaeohyphomycosis. We describe some typical phaeohyphomycotic cysts. A 59 year-old female renal transplant recipient, treated with ciclosporine and prednisone, presented with two painless nodular and suppurative lesions of the leg, extending slowly. Histological and microbiological examinations identified Exophiala spinifera. The patient's condition improved with voriconazole treatment. Phaeohyphomycosis is a rare but cosmopolitan mycosis found throughout the world. Immunocompromised hosts are more vulnerable to these infections and more likely to develop severe and disseminated forms of uncertain outcome. Mycological and histological findings are important to confirm the diagnosis. The prognosis is benign and complete cure is common in cutaneous and superficial forms. Treatment is not well defined, often empirical and usually relies on antifungals and/or complete surgical resection.

    ABSTRACT: Melanoma blood vessel metastases are very uncommon. We report the first recorded case of intravascular metastatic melanoma of the vena saphena magna. A 74-year-old woman presented with a swelling of the upper third of her left thigh and was suspected of superficial thrombophlebitis. Two intravascular black masses were excised in the vena saphena magna. Histopathologic examination showed an endovascular metastatic melanoma positively staining for HMB45 and S-100 proteins. Acral-lentiginous melanoma of her big toe was then found. Subcutaneous lymph node and chest metastases were discovered and treatment with dacarbazine was initiated, followed by treatment with fotemustine. The patient died 21 months after the diagnosis was made. Only a few cases of blood vessel metastatic melanoma have been reported. We here report the first recorded case, to our knowledge, of intravascular metastatic melanoma of the vena saphena magna. Surgical exploration allowed rapid diagnosis, and histological examination confirmed the intravascular nature of a hematogenous melanoma metastasis. This case clearly illustrates the need for histologic examination of any thrombotic material.

    ABSTRACT: Scytalidium is an endemic mold in tropical and subtropial areas. Our purpose was to study the prevalence and clinical and epidemiological features of onychomycoses due to Scytalidium in Martinique (French West Indies). We performed a prospective study on 106 patients (46 men and 60 women) with clinical onychomycosis, in the dermatological department of the Centre Hospitalier Universitaire of Fort-de-France. All patients underwent mycological sampling and were divided into two groups depending on the presence or not of Scytalidium. Age, sex, localization, clinical aspects, time of duration and environmental factors (place of residence, garden, animals, bare foot walk, immunodepression) were compared between the two groups using chi2, Fisher and Student's t test. Ten control volonteers without clinical onycomycosis underwent mycological sampling. Onychomycosis due to scytalidium represented 42 p. 100 of patients (Scytalidium hyalinum in 91 p. 100 of cases) and 56 p. 100 after elimination of patients with negative results. Medium age was significantly higher in Scytalidium group (62 versus 54 years; p<0.02). Toe nail was involved in 95 p. 100 of patients (big toe nail in 77 p. 100). Sole involvement was more frequent in Scytalidium group (47 p. 100 versus 14 p. 100; p<0.001). Sampling of controls showed scytalidium in one case. Our study confirmed the endemicity of Scytalidium hyalinum in Martinique and the frequence of sole involvement. Presence of Scytalidium without clinical features in one control is of epidemiological interest, and may explain the frequence of the disease.

    ABSTRACT: Buschke sclerodema is a very rare disease. Our objective was to show that persistent scleredema is frequent in certain group of patients at risk. We studied 49 patients, diagnosed between 1995 and 1999 in dermatology, pneumology and endocrinology departments in Martinique. Diagnosis was performed on classical clinical and histopathological aspects of sclerodema. Data studied were age, sex, mode of occurrence, clinical and histopathological aspects and associated diseases. The 49 patients presented with cutaneous infiltration of the upper part of the trunk, with thick dermis and large collagen bundles on histopathological examination. Forty-two had mucoid substance deposition, stained with Alcian Blue (this criteria was considered as inconstant by most authors in the literature). Sex ratio H/F was 0.06 (93 p. 100 females). Mediam age at onset was 50 years ranging from 20 to 79 years. The occurrence was insidious in 97 p. 100 of cases. All patients had neck and nuchae involvement. The disease involved the back in 93 p. 100, upper limbs in 50 p. 100 and lower limbs and face in 43 p. 100 of patients. Fifty-six percent of patients had limitation of shoulder movements, 16 p. 100 limitation of mouth opening, 20 p. 100 limitation of eyelid opening, 36 p. 100 had myalgia, 73 p. 100 had pruritus and 66 p. 100 had dyspnea. Obesity was present in 95 p. 100, diabetes in 79.5 p. 100, elevated blood pressure in 81.5 p. 100 and monoclonal dysglobulinemia in 46 p. 100 of patients. Twenty-five patients had a polysomnography showing severe obstructive sleep apnea syndrome. The large number of patients in our study can be explained by the search for sclerodema in patients with obesity, diabetes and high blood pressure. The disease is usually unknown by patients and physicians unless a systematic examination is performed. Association with obstructive sleep apnea syndrome was not previously reported and a larger study is ongoing.

    ABSTRACT: Exophiala jeanselmei is a dematiaceous fungus that may cause invasive diseases, particularly among immunocompromised hosts. Most reports mention cutaneous or subcutaneous lesions, but no case of nail involvement due to this fungus has been reported until now. A 60-year-old man presented with hyperkeratosis and black coloration of the nails of the two thumbs and the two big toes of 4 years' duration. He was a renal transplant recipient and had been treated with prednisone and azathioprine. E. jeanselmei was present on direct examination, then isolated in cultures on repeated samplings from all pathologic nails. He was cured after 6 months of treatment with itraconazole. We describe the first case of nail infection due to E. jeanselmei. Itraconazole, which provides a broad spectrum of action on fungal species and achieves high levels of active substance in many tissues, including the nails, appeared to be efficient upon such a nail localization of E. jeanselmei.

    ABSTRACT: Drug-induced panniculitis are uncommon. We report the second case of panniculitis induced by MINE chemotherapy. A 31-year-old woman with relapsed Hodgkin disease was treated with MINE cytostatic regimen. Multiple erythematous and painful nodules of panniculitis developed on her chest, abdomen and thighs fifteen days after the beginning of drug administration with a second flare up after second administration of the same drugs. The eruption cleared slowly after treatment withdrawal. To our knowledge, our case is the second reported case of panniculitis induced by MINE chemotherapy. Drug-induced panniculitis is uncommon and usually induced by steroid treatment. Some cases of panniculitis induced by atenolol, potassium bromide, apomorphine, interferon alpha and interleukin 2 have been described. Few cutaneous adverse effects are reported with MINE chemotherapy: rash, erythema and swelling of extremities. A case of inflammatory swelling of thighs with hemorrhagic panniculitis due to this treatment has been described recently.

    ABSTRACT: The frequency of vitiligo in white populations has been generally estimated to be about 0.5-1%. The same prevalence is expected in black populations, despite the few investigations reported. No studies have been performed in black populations living in the Caribbean Islands. Therefore, our purpose was to report an epidemiologic study of vitiligo in the French West Indies (Isle of Martinique). We performed a prospective study between October 1995 and March 1996; 2077 outpatients of the Department of Dermatology at the Fort de France University Hospital were examined to detect vitiligo. Concurrently, 32 patients (23 women and nine men), presenting with vitiligo, were questioned about their family history, personal diseases, age, and circumstances of vitiligo occurrence. Vitiligo was found in seven patients (five women and two men) out of 2077. The prevalence in the studied population was 0.34%. Of the 32 patients with vitiligo who were investigated, 11 (34%) had a family history of vitiligo, two (6%) suffered from thyroid disease, two (6%) from psoriasis, and one (3%) from atopic dermatitis. The median age at vitiligo onset was 29 years. Despite the bias due to the recruitment of patients in the Dermatology Department, this study demonstrates a prevalence in a black population comparable, or slightly inferior, to the currently accepted data in white people. Our results concerning the age of onset and pathologic associations showed no difference with the literature data related to white populations.

    ABSTRACT: Histoplasma capsulatum infection is considered to be endemic in the West Indies. Nevertheless, few epidemiologic studies have been conducted in this area. The histoplasmin skin test reflects the frequency of asymptomatic forms of histoplasmosis. We studied the prevalence of positive skin tests in a population of the French West Indies (Martinique). Forty one patients (24 females and 17 males), age range 29 to 90 years, were tested for histoplasmin skin sensitivity between August and October 1997, in the department of dermatology of Fort de France (French West Indies). Patients with immunosuppression or personal history of histoplasmosis were excluded. Five patients had a positive skin test (12 p. 100). No significative association was found between a positive skin test and diabetes, rural occupations or exposure to bats. Despite the small number of cases, related with difficulties in obtaining histoplasmin, our study showed a sensitivity level similar to medium endemic areas of the USA. The positive skin test rate is much higher than the rate reported before in West Indies, in a sample of the population under 25 years of age.

    ABSTRACT: The Caribbean islands are presumed to be an endemic zone for Histoplasma capsulatum infection, but no epidemiological studies have been done in this area. Our purpose was to report the epidemiology of histoplasmosis from 1991 to 1997 in the French West Indies (Martinique). Cases identified from the register of the mycology laboratory were analysed retrospectively. Ten cases (9 male and 1 female) were identified; 8 of the patients were infected with HIV (average T4 lymphocyte count in these 8 patients was 32/mm3). Eight patients had cutaneous involvement. The incidence in AIDS patients was 1.7%. The annual incidence in the general population was 0.34/100,000. Our data showed that histoplasmosis is endemic in Martinique, with an incidence in AIDS patients slightly inferior to that in endemic areas of the USA. The high rate of cutaneous forms (80%) is uncommon.
