Abstract

Umbilical cord neoplasms are rare. Teratomas, which are accepted as the only true neoplasms at this site, are exceptional. These tumors are polymorphic in their presentation and are often associated with other abnormalities, with exomphalos being the most common abnormality. Histologically these tumors show mature tissues from all the three-germ layers. Immature elements as seen in our case are rare. Germ cells which have gone astray during embryonic development are thought to be the cells of origin of these tumors.

摘要

脐带肿瘤很罕见。畸胎瘤被认为是该部位唯一真正的肿瘤，但也很罕见。这些肿瘤表现多样，常与其他异常相关，脐膨出是最常见的异常。从组织学上看，这些肿瘤显示出所有三个胚层的成熟组织。像我们病例中所见的未成熟成分很罕见。在胚胎发育过程中迷路的生殖细胞被认为是这些肿瘤的起源细胞。
