Parosteal lipomas are rare benign tumors accounting for less than 0.1% of all primary bone tumors. Only 3 cases of parosteal lipoma have been previously described affecting the distal and middle phalanges. We describe a case of parosteal lipoma in a 45-year-old man involving the proximal phalanx of the right middle finger. The tumor was marginally excised with the osseous attachment. There was no clinical or radiological recurrence at a follow-up of 2 years, with full range of movement at the proximal interphalangeal joint.
