Congenital mastocytomas in a Holstein calf.
Congenital defects occur infrequently in cattle. In this report, a stillborn Holstein calf was presented for unusual nodules in the skin. Necropsy and histopathologic findings aided in the diagnosis of systemic mastocytoma, or mast cell tumor. The diagnosis of congenital mastocytoma in this case is extremely rare and unique.
