Sporotrichosis.

Forty-nine patients with culture-proven sporotrichosis were treated between 1957 and 1986. Infections were lymphocutaneous in 36 patients, pulmonary in two, intraarticular in four, and involved multiple deep tissues in seven. Thirty-six infections involved an upper extremity. Five patients with deep infection had some evidence of being immunocompromised. Delay in diagnosis after presentation averaged 4 months overall and 25 months for those with deep infection. Ten of 12 joint infections resulted in significant functional impairment. Treatment with saturated potassium iodide solution was effective for lymphocutaneous infection. Four patients with infection of deeper tissues remain infected despite multiple operations and systemic courses of antifungal medication.
