Abstract
A 56-year-old woman presented with an enlarging soft-tissue mass of the left ring finger, causing worsening range of motion in the metacarpophalangeal and interphalangeal joints. Excision of the mass was performed and a 3.5×3.5×3 cm lipoma was found displacing the digital neurovascular bundles laterally and posteriorly. Surgical pathology revealed a rare angiolipoma. This case was unusual because of the location of the mass, and the fact that it was non-tender, and larger than the typical angiolipoma presentation. Definitive identification of angiolipomas, especially those without gross vascularisation, as in this case, is often delayed until final pathology. Reporting cases of angiolipoma of the finger will increase awareness of this rare lesion and broaden the differential diagnosis to improve identification and management in future cases. We discuss a surgical approach which successfully increased range of motion of the hand and preserved neurovascular integrity.
