Abstract

Tinea corporis is dermatophytosis of trunk and extremities except terminal hair present region. We report a case of psoriasiform tinea corporis in a 11-year-old girl. The lesions were showed multiple, pruritic, thick scaly erythematous macules and patches on the left forearm and trunk. She had been treated with topical and oral corticosteroid for 5 months. Direct microscopic examination and fungal culture were positive for hyphae and colonies of Microsporum canis. Histopathologic examination of the skin lesion revealed parakeratosis, psoriasiform epidermal hyperplasia and perivascular inflammatory infiltration in upper dermis with presence of fungal hyphae in stratum corneum. She was treated with 250mg of terbinafine daily and topical lanoconazole for 1 month. Skin lesions cured without recurrence.
