Isolated medial cuneiform tuberculosis: a case report.

Skeletal involvement in extrapulmonary tuberculosis is extremely rare, and foot involvement accounts for less than 10% of osteoarticular tuberculosis. Tuberculosis osteomyelitis of the foot can also mimic a wide range of pathology. As a result, this condition is often misdiagnosed, or the true nature of the lesion is identified late in the diagnostic process. This article reports a case of tuberculosis in the medial cuneiform of a 3-year-old girl. Initially misdiagnosed as osteochondrosis, the patient returned 2 years later with a draining sinus on the medial aspect of the left midfoot. New radiographs showed a cystic lesion in the substance of the medial cuneiform. A diagnosis of tuberculosis was established after biopsy and histopathological examination of operative specimen. Antituberculosis treatment was implemented and continued for 16 months. At that time, clinical signs of infection had ceased.
