Traumatic axial dislocation of the carpus: a case report of transscaphoid pericapitate transhamate axial dislocation.

Traumatic axial dislocation of the carpus in a 20-year-old man is described. This injury was accompanied by a crushing injury to the hand. The disruption pattern was different from those of previously reported cases.

Intraarticular synovial sarcoma confirmed by SYT-SSX fusion transcript.

A case of intraarticular synovial sarcoma arising in the knee verified by detection of the tumor-specific SYT-SSX fusion transcript is described. Although it is extremely rare, synovial sarcoma may occur entirely within a joint space. The molecular assay for detecting a tumor-specific chimeric gene is a valuable tool for diagnosis of soft tissue sarcoma, especially for diagnostically difficult cases and tumors in unusual locations.
