We report a case of cat-associated sporotrichosis. A 16-year-old boy with fixed cutaneous spomtrichosis caused by Sporothrix schenckii presented with hyperplasia, exudation and crusts. We present the clinical manifestation, histopathological presentations, microscopic examination and fungal culture of sporotrichosis. After seven monthes treatment of potassium iodide and terbinafine ointment,the lesion disappeared.
