Adrenal hemangiomas are rare non-functioning tumors that originate from the retroperitoneal organs. They are generally asymptomatic, and are usually discovered at autopsy. In 1955, Johnson and Jeppensen reported the first case of a surgically removed adrenal hemangioma. We report a case of adrenal hemangioma that mimicked a pancreatic tail tumor, as detected by computed tomography. We made a diagnosis of an adrenal hemangioma from endoscopic ultrasonography and confirmed the diagnosis following a laparascopic adrenalectomy. If one is suspicious of an adrenal hemangioma, one needs to assess the lesion from every aspect. With the advancement of diagnostic techniques in arteriography, ultrasound, and computed tomography, the frequency of preoperative recognition and diagnosis is on the increase. Still, it is difficult to diagnose an adrenal hemangioma just from an imaging study. One should consider performing surgery for removal of the tumor to rule out a malignancy, and to prevent traumatic rupture. With the case presentation, we review the clinical, radiographic, and pathological features of adrenal hemangiomas. (J Kor Endocr Soc 23:62~65,

We identified a rare follicular thyroid carcinoma (FTC) metastasis to the pancreas in a patient of FTC. A 65-year-old woman presented at our hospital for evaluation of a pancreatic mass. She had a history of FTC. After total thyroidectomy, I-131 whole body scan showed increased I-131 uptake in the thyroid bed, but there was no evidence of distant metastasis. However, F-18 FDG PET/CT showed a mass with FDG uptake in the pancreatic head. Follow-up PET/CT showed FDG uptake in the pancreatic head and thyroid bed. Pylorus preserving pancreaticoduodenectomy was performed. Histopathological examination supported the diagnosis of metastatic FTC to pancreas.
Hypoglycemia caused by a non-islet cell tumor (NICT) is a rare condition. The mechanism of NICT-induced hypoglycemia is still unclear, but insulin-like growth factor-II (IGF-II) has been thought to play a major role in its development. NICT is usually of mesenchymal or epithelial cell origin, but reports on NICT of an endothelial cell origin, which causes hypoglycemia, have yet to surface. Here, we report on a case of a 63-year-old female patient who was diagnosed with epithelioid hemangioendothelioma-induced hypoglycemia.Epithelioid hemangioendothelioma is a borderline malignant vascular tumor that is of endothelial cell origin and usually occurs in soft tissue, skin, lung, and liver. It was observed that serum insulin, C-peptide, and IGF-I were reduced, but the IGF-II level was elevated in hypoglycemia. The PET-CT showed no abnormal glucose metabolism in the tumor. Dextrose fluid was administered to the patient to control hypoglycemia until the operation. For treatment and diagnosis, surgical resection of the tumor and total hysterectomy were performed.The specimen was noted to have epithelioid hemangioendothelioma. Hypoglycemia-related symptoms disappeared after surgical resection was performed.
