The etiopathogenesis of congenital tumors in bovine fetuses and neonates is largely unknown, and their diagnosis is often challenging. Here we review the literature on congenital tumors in cattle and report 11 additional cases diagnosed at veterinary diagnostic laboratories in Argentina, Uruguay, the United States, and the United Kingdom, namely 4 congenital lymphomas, 3 mesotheliomas, 2 adenomatoid tumors, 1 lymphangioma, and 1 ovarian sex cord-stromal tumor in bovine fetuses and/or neonatal calves. Lymphomas, mesotheliomas, melanomas, and mast cell tumors were reported most commonly in the literature. © 2025 The Author(s).  aBovine  aCancer  aCongenital neoplasms  aNeonatal neoplasia  aPLATAFORMA DE INVESTIGACIÓN EN SALUD ANIMAL - INIA1 aGIANNITTI, F.1 aMACÍAS-RIOSECO, M.1 aCOLQUE CARO, L.
