Tinea Cruris - Symptoms and Signs

Symptoms and Signs

As the common name for this condition implies, it causes itching or a burning sensation in the groin area, thigh skin folds, or anus. It may involve the inner thighs and genital areas, as well as extending back to the perineum and perianal areas.

Affected areas may appear red, tan, or brown, with flaking, rippling, peeling, or cracking skin.

The acute infection begins with an area in the groin fold about a half-inch across, usually on both sides. The area may enlarge, and other sores may develop in no particular pattern. The rash appears as raised red plaques (platelike areas) and scaly patches with sharply defined borders that may blister and ooze.

If the rash advances, it usually advances down the thigh. The advancing edge is redder and more raised than areas that have been infected longer. The advancing edge is usually scaly, and very easily distinguished or well demarcated.

The skin within the border turns a reddish-brown and loses much of its scale. The border may exhibit tiny pimples or even pustules, with central areas that are reddish and dry with small scales.

If infected with candidal organisms, the rash tends to be redder and wetter. The skin of the penis may be involved, whereas other organisms spare the penis.
