Case in brief

During forearm surgery, an accessory flexor muscle was identified incidentally. It was a type V variant of palmaris profundus, a rare muscle with several recognized forms. The abstract does not report symptoms attributable to the muscle, further diagnostic findings, or a specific intervention for it; the finding was made intraoperatively.

What made this case unusual

The finding was the reversed type V variant of palmaris profundus, which may have different clinical implications from more common subtypes.

Diagnostic / clinical pearl

Palmaris profundus has multiple variants; an unexpected accessory flexor muscle encountered during forearm surgery may represent this anatomy.
