Osteoarticular sporotrichosis in an immunocompetent patient.

Sporotrichosis is a frequent subcutaneous mycosis in Madagascar. Extracutaenous forms are exceptional and are usually seen in immunosuppressed hosts. We report a case of an aggressive clinical evolution of lymphocutaneous sporotrichosis with osteoarticular involvement in an immunocompetent patient. Therapy with oral itraconazole 200 mg twice daily for 12 months improved the lesion. Early diagnosis of Sporothrix schenkii infection is critical to prevent complications including osteoarticular involvement, disseminated forms and death.
