A rare case of parosteal lipoma of the distal phalanx in a small finger of a 68-year-old woman is reported. Radiographs revealed an osseous projection and cortical irregularity in the distal phalanx of the right small finger. Magnetic resonance imaging showed a hyperintense soft tissue mass adjacent to the phalanx on T1-weighted and T2-weighted images. Histologically, the lesion consisted of mature fat cells. Marginal excision of the lesion was curative.
