Abstract

Microsporum canis cutaneous infection mimicking histopathologically a cutaneous T cell lymphoma is discussed. A 63 year old male presented with pruritic, erythematous thin annular, scaling plaques localized to the forearms, abdomen and left hand. A primary care physician’s biopsy raised concern for a cutaneous lymphoma. At the Dermatology clinic, a KOH and fungal culture suggested a dermatophyte infection caused by Microsporum canis. The patient was treated with oral fluconazole with resolution of most of the lesions and symptoms. This clinical improvement supported the diagnosis of tinea corporis instead of a cutaneous lymphoma. To the best of our knowledge, this is the first reported case of Microsporum canis mimicking cutaneous T-cell lymphoma.
