Adrenal myelolipomas (a. M.) are rarely occurring, benign, unilateral, hormonally inactive, mostly asymptomatic tumors of the adrenal cortex, consisting of fat cells and myeloid tissue. The pathogenesis is not clear. There is no connection with hematologic diseases, but a strikingly frequent coincidence with chronic systemic diseases and obesity. Myelolipomas of the presacral as well as in the mediastinal space are very rare. Case report of an adrenal myelolipoma removed by lumbotomy.

We report the 14th case of myelolipoma of the adrenal gland. Recommendations for appropriate diagnostic and therapeutic methods are made. Myelolipoma of the adrenal gland is a rare non-functioning tumor composed of lipoid and hematopoietic elements. The most consistent complaint is abdominal pain caused by hemorrhage within the tumor. We identified an association with obesity and hypertension. Ultrasound combined with computed tomography is useful in diagnosis. With expanded use of these studies, myelolipoma will be recognized more frequently. Definitive diagnosis and treatment are accomplished by simple excision; radical surgery is unnecessary.

Adrenal myelolipoma is an uncommon benign tumor usually discovered by chance in patients with hypertension, obesity, atherosclerosis, cancer or endocrine disorders. The association with adrenal endocrine dysfunctions appears to be the most frequent. Myelolipoma has been found in patients affected by Cushing's syndrome, hyperaldosteronism, Addison's disease, virilization. We report herein a case of association, based on clinical and radiological signs, between myelolipoma and adrenal adenoma in a patient with Conn's disease. The myelolipoma was localized in the opposite adrenal gland to that of adenoma, at difference with the other cases described.

Myelolipoma is a tumor-like growth composed of mature fat tissue and bone marrow elements. It occurs in the adrenal gland or as an isolated soft tissue mass. It may be associated with endocrine disorders such as hermaphroditism, Cushing's disease, Addison's disease and obesity of unknown cause. These lesions rarely measure more than 5 cm in diameter, although giant tumors have been reported in the literature. The fifth largest surgically resected adrenal myelolipoma in the literature is reported and its clinical associations and, macroscopic and microscopic features are discussed.

Adrenal myelolipoma is a rare, benign and biochemically inactive tumor. It is usually diagnosed incidentally by radiological methods and is known to be associated with obesity, hypertension, endocrinological disorders and some malignancies. We report herein the association of a myelolipoma with a gastrointestinal stromal tumor. To our knowledge this is the first report of such an association to date. A 67-year-old male patient admitted to our clinic with abdomimal pain and fever; he had a history of hypertension and diabetes mellitus. In physical examination, a mass involving the right quadrants was palpated. Computerized tomography revealed a right retroperitoneal mass, probably originating from the kidney or cecum. In laparotomy, the tumor (12 cm radius and 1500 g) localized on the superior of right kidney was excised. Abdomen exploration revealed another mass with 10 cm radius 100 cm distal to the ligamentum of Treitz and segmental jejunal resection and anastomosis were applied. The pathological diagnosis was reported as myelolipoma for the retroperitoneal mass and leiomyosarcoma for the jejunal mass. Myelolipoma is a benign tumor, involving mature fat and hematopoietic stem cells. Pathogenesis is still not clear and the microscopical characteristics are hematopoietic, lipoid, and reticuloid cells and megakaryocytes. Myelolipomas are reported to be associated with some other malignancies (especially renal), but this is the first report showing the association with a leiomyosarcoma. Therefore, leiomyosarcoma should also be one of the possible associations kept in mind by the physician in the diagnosis and treatment of myelolipomas.

Myelolipomas are adrenal tumors composed of both adipose and hematopoietic tissues which are rarely associated with primary aldosteronism (PA). Here, we report a case of myelolipoma associated with PA. Aldosterone hypersecretion from bilateral adrenal glands had been confirmed by adrenal venous sampling and pathological analyses, but PA was clinically cured after surgical removal of the unilateral adrenal gland together with the myelolipoma that was not producing aldosterone. It is suggested that myelolipomas may release some factors which stimulate aldosterone production in adrenal glands, although further investigation is necessary. Obesity-related hyperaldosteronism might in part participate in generation of hypertension in the present case.
