title: Parosteal lipoma of the rib.
abstract: Parosteal lipoma is a rare benign tumor that is composed mainly of benign mature lipocytes, and it has an intimate association with the underlying periosteum of affected bone. Parosteal lipoma involving the rib is quite rare. We believe that only four cases have been previously reported in the English literature. Here we describe an exceedingly rare case of parosteal lipoma that developed in the right seventh rib, which presented in a 50-year-old man having a previous history of trauma at this site.
