ABSTRACT
Os autores descrevem um caso de feohifomicose com lesao verrucosa no halux esquerdo. O paciente nao apresentava sinais clinicos de deficiencia imunologica. Os exames direto e histopatologico mostraram celulas leveduriformes e poucas hifas septadas, demacioides, essenciais ao diagnostico desta micose. O cultivo em lamina permitiu identificar o hifomiceto como Biopolaris hawaiiensis.

A case of phaeohyphomycosis caused by Bipolaris hawaiiensis is reported. The patient, an immunocompetent host, presented a verrucous lesion on the first finger of the left foot. Dematiaceous septate hyphae and yeast-like elements were seen in direct and histological examination. The isolated strain was identified on the basis of micro and macromorphological aspects. Treated with electrocoagulation, the lesions healed and presented no relapse after two years follow-up.

The authors report a case of subcutaneous mucormycosis in a diabetic patient with verrucous lesions in the fourth finger of the right hand. Initially diagnosed as a fixed cutaneous sporotrichosis case, success was obtained with the use of potassium iodide with healing of the lesion in a period of nearly 5 months. At present the patient remains under clinical observation with no treatment or relapse.
