Deep dermatophytic fungal infections, known as pseudomycetomas, are rare in domestic animals. Dermatophytic pseudomycetoma has been described in cats, dogs, equine and men. Most cases, M. canis is the fungi isolated. In the present article we report two cases of dermatophytic pseudomycetoma in cats. Lesions were characterized by nodules ranged from 1.0 to 1.5cm in diameter, friable and with purulent exudation in one case. Histologically, lesions are presented by deep granulomatous dermatitis, predominating macrophages, epithelioid cells and a discrete number of plasma cells, eosinophils, and dense hyphae aggregate surrounded by marked eosinophilic Splendori-Hoeppli reaction.
