A case of sporotrichosis misdiagnosed as lupus vulgaris was presented. A 56-year-old woman had bean to pea sized, nontender pustules and a hypertrophic-sear-like nodule on the right thigh. She denied any trauma before the lesions developed. Histopathologic findings from the lesion showed tuberculosis-like granulomatous changes. And she was diagnosed as lupus vuagaris. She also had pulmonary tuberculosis and had been treated with antituberculous drugs for 1 year. But skin lesions was not cleared. We suspected the lesions as one of deep mycoses and could confirm sporotrichosis by mycologic studies. They showed characteristic gross colonies and microscopic findings of Sporothrix schenckii.
