Abstract
Pineal tumors are rare neoplasms that are categorized into pineoblastomas, pineocytomas, and pineal parenchymal tumors of intermediate differentiation. Pineal anlage tumors are primary pineal tumors with neuroepithelial and ectomesenchymal differentiation and without endodermal differentiation. The authors review the literature and report the case of a 5-month-old boy with a pineal anlage tumor. This is only the sixth case of a pineal anlage tumor reported in the English-language literature adding to the understanding of this tumor's presentation, immunomorphological and molecular characteristics, embryological origin, radiological appearance, treatment outcome, and prognosis.
