[Digital tuberculous revealed by trauma].

Tuberculous dactylitis is an uncommon condition which is particularly difficult to differentiate from other lesions, particularly tumors. Diagnosis must be confirmed by histology and/or bacteriology studies. We report the case of a 64-year-old diabetic woman who consulted for a painful tumefaction on her fourth finger of the left hand which had developed after minimal trauma. The x-ray of the hand visualized multiple bony defects involving the second phalanx of the fourth finger and a fracture. Pathology examination of a biopsy specimen revealed granulomatous osteitis with typical caseous necrosis. The clinical signs and radiographic images resolved after anti-tuberculosis treatment.
