Abstract
This study was focused on research of the nervous component of mature cystic ovarian teratomas with generally available methods to pathologists, including impregnation techniques, immunohistochemistry and electron microscopy. The results obtained from the examination of teratomas in this study confirmed and enriched the literature data concerning the high degree of differentiation of their nervous components.
We suggest that the differentiated nervous tissue of teratoma represents a unique natural model suitable for research of some aspects of neurohistology and neuropathology, e.g. synaptogenesis or myelinogenesis.
