Comments

This specimen was sent to rule out infection. Phaeohyphomycosis is a rare treat for the dermatopathologist. When one sees pigmented hyphae, their done! And for that reason, this is a grat Boards question. These infections are often caused by Exophiala and Wangiella species. They differ from chromoblastomycosis by the presence of hyphae and budding. In chromoblastomycosis, one often only sees the copper pennies, or "Medlar bodies".

Description

This is a great image showing numerous branching pigmented hyphae. The background inflammatory reaction is mixed.
