Gallbladder Teratoma and a Review of the Literature

Teratoma is a common type of mixed germ cell tumor containing tissues from all three germ cell layers: the ectoderm, mesoderm, and endoderm. The most common teratoma site in adults is a gonad, whereas in children the most common site is the sacrococcygeal region. Teratomas rarely occur in the gallbladder; only two cases have been reported so far in the English-language literature. We present a case of a mature cystic teratoma in the gallbladder that was successfully managed via open cholecystectomy.
