Abstract:

A 35-year-old male presented with rash on the neck with itching for 2 years. He had been diagnosed as dermatitis, eczema, pityriasis rosea, etc.. Topical glucocorticoids were not effective, and the lesion was enlarging. Physical examination revealed scaly papules, plaques and pustules on the neck. Under microscopy, a large number of fungal hyphae were observed by taking scales samples from the lesion. On fungal culture, spindle-shaped macroconidia were detected, which was consistent with Microsporum canis. A diagnosis of tinea incognito was made. It was cured after antifungal therapy.

Key words: Tinea incognito, dermatophyte infection, misdiagnosis
