Delayed Diagnosis in a Case of Smoldering Sporotrichal Monoarthropathy.

We present the clinical, imaging, and laboratory findings of a 41-year-old male with culture proven Sporothrix schenckii osteoarticular infection of the right knee. Fungal arthropathies are a rare and indolent form of septic arthritis, which often leads to a delayed diagnosis. Early diagnosis and treatment of fungal arthropathies is critical to preventing permanent functional disability.
