Abstract:
Macroscopic and microscopic characteristics of 210 spontaneous ovarian tumors from 7748 Sprague-Dawley rats are described. The tumors were classified as tubular adenoma, anaplastic adenocarcinoma, papillary cystadenoma, papillary cystadenocarcinoma, mesothelioma, sertoliform tubular adenoma, Sertoli's cell tumor, granulosa cell tumor, thecal cell tumor, polycystic sex cord/stromal tumor, and lipoid cell tumor.
