Main cause of subcutaneous mycoses involving the skin is the inoculation of certain fungi.
Subcutaneous mycoses are usually acquired through traumatic implantation of the pathogens.

Phaeohypomycosis is characterized by darkly pigmented fungi.
Phaeohypomycotic cysts are noted for their unique appearance, often showing a brown-black pigmentation.

Both Actinomycotic (bacterial) and Eumycotic (fungal) subcutaneous mycoses share similarities, including local tissue involvement and difficult-to-treat infections.
