An uncommon cause of foot ulcer: tuberculosis osteomyelitis.

Tuberculous osteomyelitis is an uncommon infection that usually involves the vertebrae. An otherwise healthy young man with a chronic discharging sinus on his right foot caused by tuberculous osteomyelitis is described. The risk factors, clinical features, radiological findings, and investigations of tuberculous osteomyelitis are briefly reviewed. Tuberculous osteomyelitis usually runs an insidious course; emergency physicians should be aware of the possibility of tuberculous osteomyelitis especially when patients present with chronic unexplained musculoskeletal symptoms.
