Xanthoma of the rib without hyperlipoproteinemia

Summary 

Primary bone invasion by xanthoma is rare particularly in normolipidemic patients. In fact, lipid disorders are present in most patients. Xanthomatous lesions were observed in the ninth rib's posterior arch of a 45-year-old man with a history of labour accident. To our knowledge, this is the fourth case reported in the literature. Histologically, the lesion was characterized by a replacement of normal bone and marrow with xanthoma cells. The treatment approach consisted in a total removal of the lesion and the patient has not presented recurrences after a follow up of 10 years.
