Abstract
- Phaeohyphomycosis is an infection of humans and other animals caused by a number of phaeoid fungi. It is characterized by the development of dark-colored hyphae and other types of fungal elements in invaded tissues. Phaeohyphomycosis caused by Exophiala species is an unusual infection, but it has been reported with increasing frequency as laboratory methods for diagnosis have improved. A 68-year-old woman presented with yellowish round crusted plaque which is similar to actinic keratosis or keratoacanthoma on her right cheek. Histopathologic examination showed mononuclear cell infiltrate and dark-brown hyphae. The nucleotide sequence of internal transcribed spacer-2 was identical to that of Exophiala species. We report a case of phaeohyphomycosis mimicking skin cancer.
