Sporotrichosis with bilateral lesions. A case report.

We report on a case of sporotrichosis in which lesions occurred bilaterally on upper limbs at different periods. The patient was an 84-year-old farmer living in Tsukuba City, Japan. The first lesion appeared on the left upper arm and remained untreated. The second lesion appeared on the back of the right hand 5 years later. Findings suggesting internal metastasis could not be confirmed in various examinations. We judged that the lesion of the left upper arm was primary and the lesion at the back of the right hand was caused by autoinoculation.
