Abstract:

Teratoma is one of the common reproductive cell tumors in gynecology. Due to the specific ultrasound manifestations and clinical symptoms, it can often be diagnosed before surgery. However, gonad-extrinsic teratomas occurring on the greater omentum are extremely rare, and preoperative diagnosis is difficult. Therefore, this article reports a case of a perimenopausal female who underwent complete resection of the tumor through a single-port laparoscopy and was diagnosed with greater omentum teratoma after surgery. This serves as a warning for clinicians to make adequate preoperative preparations.

Key words:

Greater omentum, Mature teratoma, Single-port laparoscopy, Autologous resection

摘要：

畸胎瘤是妇科常见的生殖细胞肿瘤之一，由于超声表现及临床症状特异性，常在术前诊断，但发生在大网膜上的性腺外畸胎瘤十分罕见，术前诊断困难，故报道1例围绝经期女性通过单孔腹腔镜完整切除肿瘤，术后诊断为大网膜畸胎瘤，以警示临床医师做好充分术前准备。
