What does phaeohyphomycosis mean?
Phaeohyphomycosis refers to infections caused by many kinds of dark, melanin-pigmented dematiaceous fungi. It is distinguished from chromoblastomycosis and mycetoma by the absence of specific histopathologic findings. (See also Overview of Fungal Infections.
What is the cause of phaeohyphomycosis?
Phaeohyphomycosis is a chronic infectious condition caused by dematiaceous fungi which usually involve the skin and subcutaneous tissue. Subcutaneous phaeohyphomycosis is characterised by papulonodules, verrucous, hyperkeratotic or ulcerated plaques, cysts, abscesses, pyogranuloma, non-healing ulcers or sinuses.
What is the characteristic of fungi causing phaeohyphomycosis?
Phaeohyphomycosis is a diverse group of fungal infections, caused by dematiaceous fungi whose morphologic characteristics in tissue include hyphae, yeast-like cells, or a combination of these.
What are dematiaceous fungi examples?
Dematiaceous fungi: Chromoblastomycosis, Mycetoma, Phaeohyphomycosis.
How is Phaeohyphomycosis transmitted?
Subcutaneous phaeohyphomycosis usually follows the traumatic implantation of the fungus into the subcutaneous tissue. Minor trauma, such as cuts or wounds from thorns or wood splinters, is often sufficient. The principal etiologic agents include E.
Where is Phaeohyphomycosis found?
Phaeohyphomycosis is a rare infection caused by dematiaceous fungi, involving the skin and subcutis, paranasal sinuses or central nervous system (CNS).
How is Phaeohyphomycosis treated?
Treatment: Phaeohyphomycosis is generally poorly responsive to treatment. Wide excision of cutaneous or subcutaneous lesions is recommended, followed by 6–12 mo of treatment with itraconazole (10 mg/kg/day). Nonresectable disease should be treated with itraconazole.
What Melanized fungi?

What is the difference between Chromoblastomycosis and Phaeohyphomycosis?
Where can I find Melanized fungi?
