The diagnostic feature of phaeohyphomycosis is the presence of brownish melanized, septate hyphae within the lesions. The hallmark of a mycetoma is localized swelling and the formation of fistulae that contain hard granules composed of hyphae and inflammatory tissue eg, macrophages, fibrin. Sporothrix schenckii, the cause of sporotrichosis, is a dimorphic fungus that conves from hyphal growth to yeast cells within the host. Ref: Brooks G.F. 2013. Chapter 45. Medical Mycology. In G.F.
