[Pseudotumoral tuberculosis of bone. About a metacarpal case report]

Metacarpal tuberculosis is a very rare form of the disease; it represents 1% of all bone sites. The diagnosis is often difficult because of the non-specific nature of the clinical examination and X-rays. Specialised morphological investigations are a capital contribution, but histology is diagnostic. Specific chemotherapy, combined with a bony debridement, generally allows desiccation of the bacilli in the lesions and the fixation of bone lesions. We report a case with the intention of pointing out the rarity of this location, the difficulty of diagnosis that may be encountered, and to highlight the severity of bone lesions that are mainly due to their late diagnosis.
