Abstract
A 1-day-old male calf presented with clinical signs of severe progressive abdominal distension. Abdominal radiographic and ultrasonic images revealed several loop-like structures in the small intestine, which were indicative of gas retention. Experimental laparotomy was performed. However, the calf died during surgery. At necropsy, a round, well-circumscribed mass (3 × 3 × 2.5 cm) was found in the jejunal wall, and the jejunal lumen was narrowed. The mass was firm and had white to grey appearance on the cut surface. Histologically, the submucosa and the muscle layer were diffusely thickened due to abundance of neural tissues comprising several fascicles of nerve fibres and large aggregates of ganglion cells. Some ganglion cells contained basophilic Nissl substances in their cytoplasm. Immunohistochemically, these cells were positive for S-100 and synaptophysin. Ultrastructural examination revealed that the neoplastic ganglion cells contained dense core vesicles in the cytoplasm. Based on these findings, the neoplastic lesion was diagnosed as ganglioneuroma in the jejunum.
