title: Bone tissue in adrenal myelolipoma: a case report.
abstract: This paper describes a case of adrenal myelolipoma with an unusual characteristic: the presence of bone spicules. The lesion was associated with an accessory adrenal gland containing foci of myeloadiposis. The authors believe that myelolipoma and myeloadiposis are closely associated and are in fact the expression of a single process that is both focal (myeloadiposis) and diffuse (myelolipoma). The process consists of the differentiation of choristomatous primitive mesenchymal cells into hematopoietic tissue, adipose tissue and, in rare cases, bone tissue.
