Suspect granulosa cell tumor. Beef cow
Keywords: beef, bovine, ovary, neoplasia, tumor, GCT, granulosa.
A large and almost spherical (the image was not re-touched in that regard) replacing the ovary on the tract of a slaughter plant specimen from a beef cow. As for others in this collection, this image from 1980 was labeled as "Ovarian cyst - beef cow". Judging by the size of the tumor and the manner in which it has replaced the ovary, is likely that this was a cystic form of a granulosa cell tumor. Granulosa cell tumors in cattle can be solid, polycystic or as in this case, may consist of a single large cyst. This is a likely diagnosis but of course, is based only on speculation.
