RESUMO
Extra-adrenal myelolipomas are rare, generally solitary, non-functioning tumors consisting of adipose tissue and hematopoetic elements. These lesions are not known to be associated with underlying hematologic disorders or documented bone marrow abnormalities. We describe the extremely rare occurrence of multifocal, extra-adrenal myelolipomas in a 35-yr-old male. A markedly hypocellular bone marrow is noted, despite normal peripheral blood counts. To our knowledge, this is the first case report of a markedly abnormal marrow examination in a patient with extra-adrenal myelolipoma, and implicates the extra-osseous masses as the driving force behind his normal hematopoesis.

Sebaceous neoplasms arising in dermoid cysts of the ovary are exceedingly rare. We report a well-differentiated sebaceous carcinoma arising in a dermoid cyst in a 39-year-old female, the fourth such case in the literature.
