Tinea Types: Tinea Cruris

By Dr Robert P. Blereau.

A 56-year-old man had an asymmetric, maculopapular, sharply demarcated, pruritic, excoriated dermatitis on his upper thighs.

The eruption had been present for 2 to 3 weeks. A potassium hydroxide( preparation revealed fungal elements.

Unlike a Candida infection of the groin, tinea cruris usually is more confined and spares the scrotum.

Oral and topical ketoconazole( were given; the dermatophytosis completely resolved in 3 weeks.
