title: Primary costal myelolipoma: a case report and review of the literature.
abstract: Extra-adrenal myelolipoma is an uncommon entity. But myelolipoma located in the bone is extremely rare. We report a case of myelolipoma occurring in an unusual site: the Costa. It was demonstrated by Computed tomography (CT) scan that an expansive bony mass with heterogeneous low density contents adhered to the 6(th) ribs. The mass was successful resected and which was yielded to a bony lump through grossly inspection. Histological, the mass was confirmed as an intraosseous myelolipoma, with mature adipocytes mixed with hemopoietic cells. To the authors' knowledge, it is the first reported that myelolipoma located in the rib in human beings.
