[Digital tuberculous revealed by trauma]. / Une tuberculose digitale révélée par un traumatisme.

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.
