Unusual Presentation of Subcutaneous Phaeohyphomycosis by .

The species are dematiaceous fungi. Human infection due to dematiaceous fungi is uncommon. Most reported cases of alternariosis have occurred in patients with immunodeficiency. The majority of cases were solid-organ transplantation recipients. Cutaneous alternariosis lesions are usually asymptomatic solitary nodules, plaques of ulcers or subcutaneous cysts. Here we report a case of a 77-year-old female who presented with hemorrhagic skin necrosis in right arm that had developed from hemorrhagic bullae. Her prior medical history included iatrogenic Cushing's syndrome, hypertension, interstitial lung disease and congestive heart failure. Following administration of itraconazole, her lesions improved.
