肝臟腎上腺皮質腫瘤模仿肝細胞癌──病例報告

Hepatic Adrenal Cortical Adenoma Mimicking Hepatocellular Carcinoma - A Case Report

肝臟的腎上腺皮質腫瘤並不常見，大部分位於肝臟的右後葉。大多數肝臟的腎上腺腫瘤是無症狀且無功能性的。由於其含有豐富的血管，故在影像上與肝細胞癌具有相似的特徵。本篇病例報告我們提供一例最初被懷疑為肝細胞癌的腎上腺皮質腫瘤。病理形態學和免疫組織化學染色有助於鑑別兩種細胞來源。因此，當肝臟腫瘤位於腎上腺附近時，應將腎上腺皮質腫瘤一併納入鑑別診斷。

Hepatic adrenal cortical neoplasms are rare and are predominantly located in the right posterior section of the liver. Most hepatic adrenal tumors are asymptomatic and non-functioning. Due to their hypervascularity, they exhibit radiological features resembling hepatocellular carcinoma. We report a case of hepatic adrenal cortical adenoma initially suspected to be hepatocellular carcinoma before surgical intervention. Pathological morphology and immunohistochemical stains assist in identifying the tumor’s origin. Therefore, consideration of hepatic adrenal cortical adenoma should be given when a hepatic neoplasm is in close proximity to the adrenal gland.
