Tinea Incognito

Tinea incognito is a fungal infection (mycosis) of the skin caused by the presence of a topical immunosuppressive agent. The usual agent is a topical corticosteroid (topical steroid). As the skin fungal infection has lost some of the characteristic features due to suppression of inflammation, it may have a poorly defined border, skin atrophy, telangiectasia, and florid growth. Occasionally, secondary infection with bacteria occurs with concurrent pustules and impetigo.
