肾上腺发生的髓质脂肪瘤,是一种无功能的良性肿瘤,组织学上是造血组织或脂肪组织。1905年首先被Gierke描述,1929年Oberling定名为髓质脂肪瘤(Myelolipoma)。本疾病常在剖检时被偶然发现。近年来,由外科手术切除的报告增多。本文作者报道1例经手术切除和病理证实的肾上腺髓质脂肪瘤。患者为45岁男性,主诉为腹部肿块。6年前有左肾上腺巨大肿瘤切除史。近年来发生无痛性血尿,并出现腹部肿块,经CT检查,证实为右侧腹膜后肿块而收住人院。住院检查发现巨大肿块在右季肋部并波及回盲部,表面光滑,随呼吸运动上下。实验室检查 Adrenal medullary lipoma is a non-functioning benign tumor that is histologically hematopoietic or adipose tissue. First described by Gierke in 1905, Obering was named in 1929 as Myelolipoma. The disease is often accidentally discovered during a necropsy. In recent years, reports of surgical removal have increased. The authors report a case of adrenal medulla lipoma that was surgically and pathologically confirmed. The patient was a 45-year-old man who complained of an abdominal mass. 6 years ago there was a history of massive resection of the left adrenal gland tumor. In recent years, painless hematuria occurred, and abdominal masses appeared. CT examination confirmed the right retroperitoneal mass and was admitted to the hospital. The hospital examination revealed a huge mass in the right quarter rib and spread to the ileocecal area, with a smooth surface and up and down with respiratory movements. Laboratory inspection
