Mycoses

Fungal infections.

Superficial mycoses

Affect the cutaneous cornified layer of the skin and portions of the hair.

Pityriasis versicolor, tinea piedra, tinea nigra

Examples of superficial mycoses.

Cutaneous mycoses

Caused by fungi (dermatophytes) that infect only superficial keratinized tissues, including the skin, hair, and nails.

Tinea corporis

Ringworm.

Tinea pedis

Athlete's foot.

Dermatophytid

Also known as an id reaction.

Subcutaneous mycoses

Generally acquired when fungi from the soil enter through the skin and infect the subcutaneous tissue. Lesions become granulomatous and expand slowly from the implantation site. Extension through the draining lymphatics is slow, except in sporotrichosis.

Sporotrichosis

Caused by Sporothrix.

Lobomycosis

Also known as lacaziosis.

Mycetoma

Caused by eumycetes (fungi) or actinomycetes (bacteria).

Chromomycosis

Caused by dematiaceous fungi.

Rhinosporidiosis

Caused by Rhinosporidium seeberi.
