The intention of this report is to heighten the practitioner's clinical suspicion of intraosseous lipoma of the calcaneus. The apparent infrequency of this diagnosis may be attributed to the dependence on radiographic evaluation and the use of closed needle biopsy. Thus, to make a proper diagnosis, a computed tomography scan with the rate of attenuation and, ultimately, a large tissue biopsy with attentive gross and microscopic examination are necessary.
