Among uterine cystic tumors, uterine cyst arising from secondary Müllerian epithelium is exceedingly rare. A 45-year-old woman presented with pelvic cystic mass, which was initially diagnosed as a paraovarian cyst by ultrasound and magnetic resonance imaging. At laparoscopy, the cyst proved to be a pedunculated uterine cyst, which was easily resected. Histologically, the cyst wall was lined by fallopian epithelium and positively stained for WT-1, estrogen receptor, and progesterone receptor. The final diagnosis was Müllerian cyst of the uterus. Preoperative diagnosis of uterine Müllerian cyst is usually impossible. Laparoscopy is useful as a minimally invasive treatment to diagnose and resect the cyst at the same time. Specific immunostaining is useful to make a definite diagnosis of Müllerian cyst of the uterus.
在子宫囊性肿瘤中，起源于继发性苗勒上皮的子宫囊肿极为罕见。一名45岁女性因盆腔囊性肿物就诊，超声和磁共振成像最初诊断为卵巢旁囊肿。腹腔镜检查时，该囊肿被证实为有蒂子宫囊肿，易于切除。组织学上，囊肿壁内衬输卵管上皮，WT-1、雌激素受体和孕激素受体染色呈阳性。最终诊断为子宫苗勒囊肿。子宫苗勒囊肿术前通常无法诊断。腹腔镜检查作为一种微创治疗方法，可同时用于诊断和切除囊肿。特异性免疫染色有助于明确诊断子宫苗勒囊肿。
