Alternaria species are a group of dematiaceous fungi that are ubiquitous in nature and are becoming an increasingly important cause of disease in immunocompromised patients. We present a case of a 70 year old renal transplant recipient with multiple areas of cutaneous Alternaria infections likely introduced during local trauma. Treatment has required a combination of systemic therapy and surgical excision. This case illustrates the importance of recognizing fungal infections with cutaneous manifestations, such as alternariosis, in immunosuppressed patients.
