    Abstract:
    BACKGROUND: Chromomycosis is a chronic fungal skin infection that generally presents in the form of verrucous or vegetative lesions on uncovered areas of skin. We report an unusual case of generalised chromomycosis due to Phialophora verrucosa. PATIENTS AND METHODS: A 42-year-old town-dwelling housewife was hospitalised for erythematous keratotic nodules on the arm showing sporotrichoid distribution, associated with a crusted ulcerative lesion on the homolateral index finger, as well as subcutaneous papulonodular lesions. In places, the lesions on the patient's back presented an umbilical and molluscoid appearance. The patient had suffered no previous injuries and had not visited any areas in which leishmaniasis is endemic. Her history included insulin-dependent diabetes. Screening for Leishman bodies was negative. Histopathological analysis of the skin biopsy revealed an epithelioid giant-cell granuloma with no caseous necrosis. The mycological study demonstrated the presence of fumagoid bodies and P. verrucosa was isolated. Treatment with terbinafine was initially given, followed by clarithromycin, but in the absence of any improvement, the patient was readmitted to hospital and is currently on itraconazole and amphotericin B. DISCUSSION: The novel features of our case comprise the clinical aspect of chromomycosis, the extent of the lesions, their unusual site on the back and upper limbs, and the isolation of a rare species, P. verrucosa (only the second observation in Morocco). It also highlights the therapeutic difficulties posed by this type of chromomycosis.
