Variations of the muscle belly and tendon of flexor digitorum superficialis to the fifth digit are common. We encountered an unusual variant during routine educational dissection; an accessory tendon of flexor digitorum superficialis that united with the tendon of flexor digitorum profundus to the fifth digit. This variant is not documented in the literature. Known variations of flexor digitorum superficialis to the fifth digit are discussed to allow for comparison with the variant identified in this report. The potential clinical significance of the variant is speculated upon.
