摘要
目的探讨肾黏液性乳头状囊腺瘤的临床、病理学特点及治疗方法。方法回顾性分析华北油田总医院诊治的1例肾黏液性乳头状囊腺瘤患者的临床资料,并复习文献。结果本例肾黏液性乳头状囊腺瘤上腹部无包块,伴有腹痛,肿瘤直径10 cm。肿瘤包膜完整,与周围很少粘连。切面为囊性(单囊或多囊),充满灰白或灰红色胶胨状液体。光镜下囊壁内侧可见被覆单层黏液柱状上皮,可呈乳头状增生。肾实质内可见肾小球、肾小管萎缩,细胞核无明显异型性和核分裂象。行患侧肾全切除术后随访32个月,未见肿瘤复发和转移。结论肾黏液性乳头状囊腺瘤临床表现不典型。术前诊断困难。可行患侧肾全切除术,预后良好。
Objective To investigate the clinical and pathologic features and treatment of papillary mucinous cystadenoma of kidney. Methods The clinical data of one patient with papillary mucinous cystadenoma of kidney were retrospectively analyzed. Results The principal symptom of papillary mucinous cystadenoma of kidney is no lump in the upper abdomen with abdominal pain. The tumor measures 10 cm in diameter. The tumor has complete packing membrane,and not adhere to the adjacent tissue. On the cut section,there are one or multiple smooth - walled dilated cystic areas,some of which are filled with grey or brown jelly - like fluid. Under light microscopy,mucus columnar epithelium can be seen on the inner wall of the capsule,papillary hyperplasia may also exist. Atrophy of glomerulus and kidney tubules can be seen in renal parenchyma, cell nucleus shows no atypia and mitosis. The patient received nephrectomy and were followed up for 32 months,no recurrence and metastasis were found.
