A rare complication of pectoralis major rupture.

Pectoralis major rupture is an uncommon injury. Only 85 cases have been reported in the literature. Rupture may be partial or complete. The treatment of partial rupture is conservative, whereas in cases of total rupture surgical repair is advocated, particularly in young active patients. Complications are few. We describe a case of infection of the haematoma following a partial rupture. To the best of our knowledge it is the first case to be reported in the English literature.
