Abstract
Breast fungal infections are rare in nonlactating women. The present report is the first to describe a necrotizing cutaneous breast fungal infection. A 50-year-old woman with a remote history of breast cancer and autologous tissue reconstruction presented with a progressive cutaneous necrotic infection one year after implant augmentation of the reconstruction. Multiple eschars developed on the left breast, and pathological examination of debrided tissue revealed numerous fungal hyphae invading the epidermis, dermis and adipose tissue of the breast. Fungal cultures yielded Bipolaris species. She was treated with voriconazole. Five months later, the patient presented with an eschar on her back, indicative of disseminated disease.
Bipolaris species are dematiaceous fungi; cutaneous or disseminated infections with Bipolaris species have rarely been reported in immunocompetent patients. Unresectable or recurrent lesions should be treated with antifun-gals. Cutaneous necrotizing breast fungal infections should be considered in patients who do not respond to antibacterial therapy.
