title: [Tumors of the ovaries in zebus].
abstract: In a total of 112 slaughtered sterile cows of the Zebu cattle, originating from the Camaguey region, Cuba, 25 tumors were found in 22 animals (in three of the cows the tumors were bilateral). Histologically, the tumors were differentiated as follows: 1 papillary adenoma, 6 papillary cystadenomas, 1 adenocarcinoma, 1 papillary adenocarcinoma, 8 granulosocellular tumors, 1 thecoma, 2 luteomas, 4 hemangiomas, and 1 angiocarcinoma. In two of the cases, beside tumors there were in the ovaries parovarian cysts. The differentiation of the tumors were made on the basis of the international histologic classification of tumors of the World Health Organization. Most frequently, the tumors turned out to be granulosocellular ones as well as papillary cystadenomas and hemangiomas.
