An athlete suffering from tinea cruris would MOST likely present with which of the following?

• A. Erythematous & scaly areas on the skin
• B. Hair loss & scaly areas on the head
• C. Macerated & scaly area between the toes
• D. Scaly & pruritic rash of the groin

Answer: (D)

Fungal skin infections from dermatophytes tend to appear in characteristic locations based on moisture and friction. Tinea cruris, known as jock itch, typically affects the groin and inner thighs and presents as a scaly, itchy (pruritic) rash in that area. That specific groin localization with a scaly, pruritic eruption fits the classic pattern for tinea cruris, making it the best choice. Other common fungal infections show different sites: involvement of the scalp with hair shedding points to tinea capitis, while maceration between the toes is typical of tinea pedis. The description of erythematous and scaly skin can occur with various conditions, but without groin involvement, it doesn’t specifically identify tinea cruris.
