A case of extensor digitorum brevis manus.
The extensor digitorum brevis manus (EDBM), a relatively rare anomalous muscle on the dorsal hand, may be misdiagnosed as a ganglion, a synovial nodule or cyst, or a soft-tissue tumor. MRI scans can help to distinguish EDBM from tumors. EDBM should be included in the differential diagnosis of soft tissue masses on the dorsal aspect of the hand.
