Tinea cruris occurs in the inguinal region and does not show central clearing, unlike tinea corporis.

• A. Tinea versicolor
• B. Candida albicans
• C. Tinea cruris
• D. Tinea pedis

Answer: (C)

The key idea is how dermatophyte infections present differently depending on location. Tinea corporis usually forms an annular, scaly plaque with central clearing as the fungus expands outward. When the infection is in the groin area, as in tinea cruris, the warmth and folds of the inguinal region promote a rash that tends to be more confined to the groin and often lacks that neat central clearing pattern. This explains why the description fits tinea cruris: it’s in the inguinal region and does not show central clearing like tinea corporis does.

Other fungi cause different patterns: tinea versicolor creates hypo- or hyperpigmented patches on the trunk; Candida albicans causes red, moist intertriginous patches with satellite lesions; tinea pedis affects the feet and often shows maceration between the toes.
