Cutaneous aspergillosis.

The authors present a patient with advanced acquired immunodeficiency syndrome who developed a cutaneous lesion under the transparent dressing of a venous catheter. Histologic examination of the lesion revealed suppurative granulomatous inflammation in the dermis with numerous branching hyphae within the follicular infundibulum. A culture of the biopsy material grew Aspergillus fumigatus. Aspergillus must be considered in the differential diagnosis of cutaneous lesions in patients infected with the human immunodeficiency virus, especially when the lesion occurs under an occlusive dressing.
