Tuberculosis of the Ankle in a Non-immunocompromised Male: A Case Report and Review of the Literature.

The prevalence and incidence of tuberculosis has declined rapidly in Western Europe during the last century, although a slight increase is being seen due to immigration from countries where tuberculosis is still a common disease. We present a very rare case of primary ankle tuberculosis in a 51-year-old native German male without any risk factors or prior lung manifestation. A delay in diagnosis and treatment when a patient presents with ankle arthritis caused by Mycobacterium tuberculosis should make one aware of the possibility of primary joint tuberculosis, which is extremely unusual and it can mimic various other joint diseases. If the diagnosis is in doubt, early biopsy should be mandatory.
