[Parosteal rib lipoma: description of a case].

Abstract Parosteal lipoma is a usually indolent, rare benign tumor, characterized by clinicopathological findings similar to those of the commonly occurring subcutaneous lipoma, except for its intimate relationship with the connective tissue of the subjacent periosteal region. Parosteal lipoma commonly affects the diaphysis of long bones of the upper and lower limbs. We report an exceedingly rare case of parosteal lipoma of the rib, which presented in a 59-year-old man experiencing previous multiple traumas in this site.
