[Chondrosarcoma of soft tissue. Apropos of a case]

This article reports a case of soft-tissue chondrosarcoma in the subcutis of the right supraspinal fossa of an 18-year-old woman who had undergone irradiation in infancy. A review of 123 published cases of extraskeletal chondrosarcoma raises the question of whether or not these tumors are really malignant in patients other than children. Their relationship with previous irradiation is also examined.
