Subcutaneous Polypoid Lipoma of the First Intermetatarsal Space Mimicking Rudimentary Polydactyly

A case of a subcutaneous polypoid lipoma, presenting as a rudimentary polydactyly, is reported. The lesion was located between the first and second digits and extended into the first intermetatarsal space in a polypoid fashion. Radiographically, there were no osseous structures associated with the mass, and preliminary biopsy results showed no evidence of malignancy. The patient was treated with marginal excision of the mass and reduction of the intermetatarsal space with a Mini TightRope (Arthrex, Inc., Naples, FL). The final pathological diagnosis was polypoid lipomas, and the patient experienced a full and uneventful recovery.
