[Ulcerated nodular lesions on extremities of patient undergoing treatment for glioblastoma on French Caribbean island of Martinique].
Phaeohyphomycosis comprises a disparate group of cutaneous and systemic mycotic infections caused by dematiaceous fungi. The Exophiala genus includes more than 20 species. The purpose of this report is to describe a case of phaeohyphomycosis due to Exophiala spinifera in a patient under treatment for cerebral glioblastoma on the French Caribbean island of Martinique. A 73-year-old man who was undergoing treatment for a cerebral glioblastoma using radiotherapy, chemotherapy and systemic corticosteroids presented with ulcerated nodular lesions on all four extremities for several months. Histological and mycological examinations led to diagnosis of cutaneous phaeohyphomycoseis due to Exophiala spinifera. Treatment using itraconazole was initiated but the patient died from complications of glioblastoma. Phaeohyphomycosis is a rare and cosmopolitan mycosis. Infection due to Exophiala spinifera is uncommon in humans. It usually but not always occurs in immunocompromised hosts. Although cutaneous involvement is usually localized and has a favorable prognosis, disseminated forms may occur and can be life-threatening. Histological and mycological examinations are useful to confirm the diagnosis. Systematic antifungals with or without surgical resection are often effective. To our knowledge, only 15 reported cases of phaeohyphomycosis due to Exophiala spinifera have been reported up to now.
