[Teratoma of the umbilical cord. Case report with literature review].

Abstract

A rare case of teratoma of the umbilical cord is reported. It is differentiated from acardius amorphus and compared with the nine cases reported in the literature since the first description in 1878. The clinical consequences for pregnancy of the tumour's influence on the circulation are discussed. For the first time, non-radioactive in situ hybridization of the interphase nucleus was performed in a teratoma of the umbilical cord. The results are presented and different histogenetic pathways, e.g. parthenogenetic origin of the teratoma, are debated.
