Seborrheic dermatitis-like tinea faciei.

We report a 10-year-old Caucasian child who had erythema and abundant scaling on the nasolabial folds, the upper lip, and on the nose. Both the abundant scaling and the localization on the central part of the face led us to suspect seborrheic dermatitis. Direct microscopic examination of some scales removed from the lesions showed septate and ramified ectothrix hyphae. Cultural examination on Sabouraud medium led to the identification of the Trichophyton mentagrophytes species. We described this patient to highlight the importance of considering tinea faciei in the differential diagnosis of all facial eruptions and the value of mycologic examination.
