Chronic lymphocytic leukemia/small lymphocytic lymphoma presenting as septic arthritis of the shoulder.
We report a case of a 53-year-old man presenting with shoulder pain mimicking septic arthritis. Laboratory findings were atypical. Biopsy performed to assess for possible osteomyelitis demonstrated chronic lymphocytic leukemia/small lymphocytic lymphoma. Intra-articular lymphoma is a rare but important consideration in patients with atypical clinical presentation. Imaging alone may be insufficient to render diagnosis as lymphoma can mimic infection, synovial hypertrophic processes, and depositional arthropathy.
