tinea ver·si·col·or (vûr s -k l  r)n. An eruption of tan or brown, branny patches on the skin of the trunk, caused by the fungus Pityrosporum furfur and often appearing white in contrast with hyperpigmented skin after exposure to intense sunlight. Also called pityriasis versicolor. |
tinea versicolor,
a fungal infection of the skin caused by Malassezia furfur and characterized by finely desquamating, pale tan patches on the upper trunk and upper arms that may itch and do not tan. In dark-skinned people the lesions may be depigmented. The fungus fluoresces under Wood's light and may be easily identified in scrapings viewed under a microscope. Topical and oral antifungal agents may be used, as well as repeated applications of selenium sulfide. The pale patches may persist for up to 1 year after successful treatment, and recurrence is common.

tinea cor´poris a fungal infection of the glabrous (smooth) skin, usually due to species of Microsporum or Trichophyton.
tinea cru´ris ringworm of the groin area, starting in the perineal folds and extending onto the inner surface of the thighs; it is more common in males and is caused by Epidermophyton floccosum or species of Trichophyton; called also eczema marginatum, epidermophytosis cruris, and jock itch.
tinea fa´ciei ringworm of the face, seen on non-hairy areas of the face, often with a similar presentation to that of tinea corporis.
tinea imbrica´ta a distinctive type of tinea corporis occurring in tropical countries and caused by Trichophyton concentricum. The early lesion is circular, surrounded by a ring of scales attached along one edge; several new and larger scaling rings form later.
tinea ma´nus (tinea ma´nuum) ringworm of the hand, usually involving the interdigital spaces and palmar surfaces of the hands; it almost always accompanies tinea pedis, with the same etiologic agent for both infections.

tinea profun´da trichophytic granuloma.
tinea syco´sis an inflammatory, deep type of tinea barbae, due to Trichophyton violaceum or T. rubrum.
tinea un´guium tinea involving the nails; the invasion may be restricted to white patches or pits on the nail surface, or the lateral or distal edges of the nail may be involved first, followed by establishment of the infection beneath the nail plate.
tinea versi´color a chronic, usually asymptomatic disorder due to Malassezia furfur, marked only by multiple macular patches. Called also pityriasis versicolor.
