巨大肾脂肪瘤1例的临床诊治分析

Clinical Diagnosis and Treatment of a Case of Giant Renal Lipoma

摘要: 肾脂肪瘤为一种罕见肾实体良性肿瘤。其内部为正常的成熟脂肪细胞，外观为膨胀性肿块。一般无包膜，生长缓慢，病程较长，临床症状不明显、不典型，常因较大的肿块压迫邻近器官而出现相应的症状。肿瘤起源于脂肪细胞，可发生于肾实质，见于肾小管、肾盂及肾盏旁，一般单侧发病，大多局限于肾上极或下极皮质生长，也可发生在肾被膜。本病主要应与肾血管平滑肌脂肪瘤鉴别。现报道我院收治的1例临床上极为罕见的巨大肾脂肪瘤病例并进行文献分析，以提高泌尿外科医师对本病的认识。

Abstract: Renal lipoma is a rare benign tumor of the renal solid. Its interior is normal mature adipocytes, and its appearance is an expansive mass. Generally, there is no capsule, growth is slow, the course of disease is long, and the clinical symptoms are not obvious and typical. Often, the corresponding symptoms occur due to the compression of adjacent organs by larger masses. Tumors originate from adipocytes and can occur in the renal parenchyma, as well as in the renal tubules, pelvis, and calyces. They generally develop unilaterally, mostly confined to the cortical growth of the upper or lower renal poles, and can also occur in the renal capsule. This disease should mainly be differentiated from renal angiomyolipoma. This article reports a rare case of giant renal lipoma admitted to our hospital and analyzes the literature to improve the understanding of urologists about this disease.
