What does jock itch look like?

Generally, tinea cruris (jock itch) is a common skin condition that primarily occurs on the inner thighs, groin, and buttocks. It may present with red patches and white scaling. If discomfort occurs, prompt medical consultation at a hospital is recommended for standardized treatment under a physician's guidance. Specific details are as follows:

The typical symptoms of tinea cruris include red patches and white scaling. These lesions usually appear round or oval in shape, with clear margins and slight flaking on the surface. As the condition progresses, the red patches may gradually enlarge and spread outward. Some patients may also develop small papules and blisters. These papules and blisters may rupture, exude fluid, and form eroded areas. In the early stages, tinea cruris may present as small red spots or papules accompanied by mild itching. As the disease progresses, the red patches enlarge to form ring-shaped or semicircular lesions. In the middle stage, the lesion margins remain distinct, with slight surface scaling, and the number of papules and blisters may increase and coalesce into larger patches. In later stages, the lesions may gradually subside, leaving areas of post-inflammatory hyperpigmentation or hypopigmentation. Some patients may develop a chronic course due to recurrent episodes.

Tinea cruris is contagious to some extent; therefore, patients should avoid sharing towels, clothing, or other personal items to prevent transmission to others. Additionally, it is important to keep the affected area clean and dry, avoiding excessive scratching and hot water baths.
