Teratomas of extragonadal origin are extremely rare, and the most common extragonadal site to find teratomas is the omentum. Teratomas are typically found in women of reproductive age, but they are also seen in young girls and postmenopausal women. Generally, teratomas arise from germ cells that may induce different cells to originate from the 3 primitive embryonic layers. Three main theories have been proposed to explain their location. The present report summarizes these theories as well as describes a case of a mature cystic teratoma of the omentum that was managed by laparoscopic resection.
性腺外起源的畸胎瘤极为罕见，而发现畸胎瘤最常见的性腺外部位是大网膜。畸胎瘤通常见于育龄期女性，但也可见于年轻女孩和绝经后女性。一般来说，畸胎瘤起源于生殖细胞，这些生殖细胞可能诱导不同的细胞起源于3个原始胚胎层。已经提出了三种主要理论来解释它们的位置。本报告总结了这些理论，并描述了一例通过腹腔镜切除术治疗的大网膜成熟囊性畸胎瘤病例。
