Yolk sac tumors (or endodermal sinus tumors) are rare neoplasms of germ cell origin that have been reported in gonadal sites (testis and ovary). Extragonadal yolk sac tumors are uncommonly seen, and in particular, they are rare in the extracranial head and neck regions; we found 27 well-documented cases in the English-language literature. We discuss their clinical and pathologic features.
卵黄囊瘤（或内胚窦瘤）是一种罕见的生殖细胞起源肿瘤，已报道见于性腺部位（睾丸和卵巢）。性腺外卵黄囊瘤较为少见，尤其是在颅外头颈部区域更为罕见；我们在英文文献中发现了27例有充分记录的病例。我们将讨论其临床和病理特征。
