title: [About a rare teratoma of the pineal region (author's transl)].
abstract: 1. Report on a man aged 33 with a rare teratoma of the pineal region (adult teratoma with pinealoma-like parts) and 8 related cases of the literature. 2. The absence of the pinealis in our case and in 4 related cases of the literature is explained as a result of destruction of pinealis by the tumor. 3. The pinealis in our case cannot be considered as the origin of pinealoma-like part of the teratoma. The pinealoma-like part seems to have the same root as the teratoma. The argumentation of this opinion is the arrangement and the seize of pinealoma-like parts in the teratoma as well as the often shown proof of an unchanged pinealis and the observation of similar histological patterns in extracranial teratomas.
