Giant Extra-Adrenal Retroperitoneal Myelolipoma With Incidental Gastric Mesenchymal Neoplasias

Baris D Yildiz. Int Surg. 2015 Jun.

Abstract

Extra-adrenal myelolipomas are rare, benign tumors composed of adipose tissue and hematopoietic cells. Almost all myelolipomas occur within the adrenal gland. Only 50 cases of myelolipomas were described in literature and none of these were associated with gastric mesenchymal neoplasia. A 72-year-old male patient presented to a family medicine outpatient clinic with dyspnea and urinary urgency. His abdominal sonography revealed a 9-cm intra-abdominal mass. An incidental finding was 2 separate masses 1 cm each on the serosal surface of the stomach. The pathology specimen of the retroperitoneal mass revealed myelolipoma histopathology while gastric masses were reported as spindle cell mesenchymal neoplasias. The association of gastric spindle cell tumor and myelolipoma was not reported before in medical literature. Extra-adrenal myelolipomas are rare lesions, but should be considered in the differential diagnosis of fat containing retroperitoneal masses that are well circumscribed.
