Endometriosis is a common gynecologic disorder characterized by ectopic endometrial tissue growth outside the uterine cavity. Although usually occurring in pelvic organs, endometrial lesions may involve urinary tract. Renal endometriosis is extremely rare and it has only occasionally been reported in the past. We report two cases of patients with renal cystic lesions, incidentally found at imaging techniques during oncologic follow-up for gastric sarcoma and melanoma, initially misinterpreted as complicated haemorrhagic cysts and then histologically characterized as renal localizations of extragenital endometriosis.
子宫内膜异位症是一种常见的妇科疾病，其特征是子宫腔外异位子宫内膜组织生长。虽然通常发生在盆腔器官，但子宫内膜病变可能累及泌尿系统。肾子宫内膜异位症极为罕见，过去仅有偶尔的报道。我们报告两例肾囊性病变患者，这两例病变是在对胃肉瘤和黑色素瘤进行肿瘤学随访期间通过影像学检查偶然发现的，最初被误诊为复杂性出血性囊肿，随后经组织学检查确定为生殖器外子宫内膜异位症的肾脏定位。
