Sporotrichosis of the knee. A case report.

Articular infections due to the fungus Sporothrix schenkii are rare. Only 46 cases of Sporotrichosis arthritis have been well-documented in the English literature to date. The presentation may be limited to a monoarticular synovitis, hence the diagnosis may be confused with other more common causes resulting in costly delays in proper treatment. Reported is a case of Sporotrichosis of the knee misdiagnosed multiple times over a three-year period yet illustrating important clinical features that could lead to earlier diagnosis and management.
