Solitary fibrous tumor of the left adrenal gland associated with Doege-Potter syndrome. Case report.

We present the case of a 71-year-old man with a history of type 2 diabetes mellitus manifesting abdominal pain, weight loss, dyspnea on small efforts, muscle weakness, and left subcostal swelling. Associated with this, he developed frequent episodes of syncope, diaphoresis, and night sweats, during which blood glucose levels below 50 mg/dL and improvement were documented after the administration of hypercaloric beverages or intravenous dextrose. Abdominal computed tomography revealed the presence of a tumor of approximately 20 cm dependent on the left adrenal gland. Histopathological diagnosis of a solitary retroperitoneal fibrous tumor was obtained, confirmed by immunohistochemistry.
