title: Thymus tissue in ovarian cystic teratoma: possible clues to its histogenesis.
abstract: Thymus tissue was found in a mature cystic teratoma in conjunction with respiratory tissues. Its immunohistochemical pattern of CD99, CD3, CD68 and cytokeratins was that of the normal thymus. The main point raised by this unusual case concerns the origin of its T lymphocytes from either a tumor (parthenogenetic origin) or a secondary colonization of the teratoma from host T cells.
