title: [Undifferentiated soft tissue tumor with rhabdoid phenotype (extra-renal rhabdoid tumor). Report of a congenital case associated with medulloblastoma in a brother].
abstract: We report a case of congenital cervical rhabdoid tumor with association of a medulloblastoma in a brother. The immunohistochemical features of this tumor are compatible with a neuroectodermal differentiation (MIC 2+, Leu 7+). Extrarenal rhabdoid tumors share a common morphology but do not represent a single entity with only one histogenesis. Most of them are now considered to be of neuroectodermal origin. In our case, the association with a medulloblastoma in a brother seems to confirm this concept.
