Teratomas are rare tumors in domestic fowl, and none have been reported in the cranial area of ducks. Clinical signs and gross and microscopic findings associated with a cranial teratoma in two domestic ducks are reported. One tumor arose within the cranial vault and was associated with neurologic signs. The other tumor was subcutaneous and invaded the parietal bone but did not extend into the brain. Both tumors were tridermic.
畸胎瘤在家禽中是罕见肿瘤,鸭的颅部区域尚未见相关报道。本文报告了两只家鸭颅部畸胎瘤的临床症状、大体及显微镜检查结果。其中一个肿瘤发生于颅顶内并伴有神经症状。另一个肿瘤位于皮下,侵犯顶骨但未累及脑部。两个肿瘤均为三胚层肿瘤。
