[Isolated tuberculosis of the sternum. Two cases].

INTRODUCTION
Among the extra-pulmonary localizations, isolated tuberculosis of the sternum is rare and difficult to diagnose.


OBSERVATIONS
A 30 year-old man presented with tumefaction of the sternum that had developed over the past two months and a 52 year-old woman had developed a painful tumefaction of the sternum over the past 4 months. In both cases, the histopathological examination of a biopsy confirmed the diagnosis of tuberculosis. Anti-bacterial therapy permitted the favourable progression of the disease.


DISCUSSION
Such diagnosis is rare. Contamination can occur through contiguity, which was not manifest in either of the two cases. Confrontation between the histological and/or bacteriological samples is required.
