A 69-year-old woman presented with a 3-month history of erythematous plaques with crusts on the 2nd left finger and multiple subcutaneous nodules on her left forearm. She noted skin lesions approximately one month after the cut injuries with a knife during treating pork meat. The patient also had subcutaneous nodules on her left thigh. Past histories were unremarkable. Histopathological examination of the subcutaneous nodule showed dense cellular infiltrates comprising neutrophils and histiocytes in the deep dermis and subcutaneous tissues. Fungal cultures of the excised specimens resulted in the detection of Sporothrix globosa. No involvement of internal organs was detected. Skin lesions were successfully treated with oral potassium iodide for three months.
