[Homo- and heterotopic choriocarcinoma in 6- and 18-month-old infants].
Clinical and morphological observations of choriocarcinoma in infants of 6 and 18 months localized in the right lateral ventricle of the brain and in the sacralcoccygeal region are presented. The grounds for verification of the heterotopic tumor include the presence of one large degenerating node in the sacral-coccygeal region and the absence of neoplasia in the central nervous system, its typical histological characteristics corresponding to choriocarcinoma as well as extensive metastasizing along the lymph tracts. The dysontogenetic nature of the tumor is suggested. The difficulties of the clinical and histological diagnosis are due to the rarity of choriocarcinoma and heterotopic localization.
