Abstract:
Extensor digitorum brevis manus (EDBM) is a rare variation of the extensor muscle of the dorsum of the hand, which is found incidentally during surgery or magnetic resonance imaging (MRI). EDBM arises from the wrist capsule inferior to the extensor retinaculum, which frequently goes into the ulna side of the basis of the proximal phalanx between the 2nd and 3rd fingers. The aim of this report is evaluate to investigate the symptomatic mass on the dorsum of the hand and wrist using an image study (MRI or ultrasonography) to confirm whether it is a tumor or EDBM. Surgical excision was chosen as a treatment.
