“…The appearance of Schiller-Duval bodies, that are considered pathognomonic for YST, assures the diagnosis. [6] Immunohistochemical staining of our case showed strong positivity for AFP, pan-cytokeratin (AE1/AE3) and anti-glypican 3, further confirming the diagnosis of YST.…”

“…The presence of YST in head and neck region is even more rare, but previously has been reported in orbit, postauricular region, parapharyngeal space, nasal cavity and floor of the mouth. [678] The rarity of its occurrence in head and neck area made YST at on the last possibility of diagnosis, thus making diagnosis difficult, especially if histological appearance was not classic.…”

“…However, JGCT usually shows positive staining for sex-cord stromal tumor markers such as inhibin and calretinin. [671415] When YST appears in solid patterns, it can mimic dysgerminoma. Dysgerminoma cells are larger and have medium to large vesicular nuclei with clear chromatin and obvious nucleoli.…”

Yolk sac tumor (YST) and teratoma both categorized as germ cell tumor (GCT). YST shows preferential differentiation toward yolk sac structures, while teratoma consists of tissues that originate from at least two embryonic germinal layers. Extragonadal location of YST is rare, whereas extragonadal teratoma is majority presented in nasopharynx area. Mature teratoma tends to be benign although some malignant transformation can occur. Recurrence of teratoma was reported mostly in the case of immature teratoma. YST occurrence after removal of mature teratoma is never reported. It is extremely rare for a second GCT to occur at the same site and with a different histological type. We herein report a case of a female infant presented with YST following a congenital buccal mature teratoma.
