Desmoid fibromatosis of the shoulder and of the upper chest wall followinga clavicular fracture

A desmoid tumor of the shoulder girdle infiltrating the upper chest wail an d weighing 1500 g was almost completely removed in an 18-year-old man, 27 m onths after a bifocal fracture of the clavicule. Thirteen years later, the patient was free of recurrence. The interval time between trauma and diagno sis, as the particular characteristics of aggressive fibromatosis, strongly support a major causal role of the clavicular fracture in the occurrence o f this tumor.
