Abstract

第1例49歳男, 第2例45歳男及び第3例51歳女では健康診断の際に腹部超音波検査により偶然腫瘍が発見され, 全例高血圧エピソードを欠いていた。第1例では血中・尿中カテコラミン値上昇から褐色細胞腫が強く疑われ, 右副腎摘除術を行い, 組織学的に褐色細胞腫と診断された。第2例は内分泌的検査では殆ど正常で, 左副腎腫瘍を摘出し, 組織学的に褐色細胞腫と診断された。術中, 血圧及び心拍数は殆ど不変であった。第3例では左後腹膜腫瘍摘出を行い, 組織学的にパラガングリオーマと診断された

We present three cases of asymptomatic pheochromocytoma treated at Sumitomo Hospital. They had no hypertensive episode. The tumors of Case 1 and Case 3 were incidentally detected by abdominal ultrasonography at the Health Screening Center of Sumitomo Hospital. The tumor of Case 2 was incidentally detected by abdominal ultrasonography in the health examination of his company. Case 1. A 49-year-old male was hospitalized in Apr. 1992 because of further examination of a right adrenal mass. He underwent right adrenalectomy and its histological examination revealed pheochromocytoma. Case 2. A 45-year-old male was referred to our department for further examination of a left adrenal mass in Aug. 1993. On admission, endocrinological examination was almost normal. He underwent surgical removal of the tumor and its histological examination revealed pheochromocytoma. During the operation, blood pressure and pulse rate were almost unchanged. Case 3. A 51-year-old female was hospitalized in Oct. 1993 because of further examination of a left retroperitoneal mass. She underwent surgical removal of the tumor and its histological examination showed paraganglioma.
