Abstract

A 17-yr-old Western Hognose snake (Heterodon nasicus) presented with a prominent midcoelomic swelling. Surgical exploration revealed a large, multicystic, irregular, tan, and firm mass grossly effacing the splenopancreas. The mass was subsequently removed. Histologically, the mass was composed of tubules of columnar to flattened neoplastic cells with an abundant stroma and moderate cellular atypia consistent with a scirrhous adenocarcinoma, likely ductal in origin, given the location of the neoplastic mass. Bloodwork revealed anemia, monocytosis, marked hypercalcemia, and, postoperatively, persistent hyperglycemia. After postoperative recovery, the snake was diagnosed with iatrogenically induced diabetes mellitus and exocrine pancreatic insufficiency. Due to the inability to clinically control the diabetes mellitus and exocrine pancreatic insufficiency and when additional palpable masses were noted, the snake was euthanatized. Necropsy and histopathologic examination confirmed metastasis of the previously removed adenocarcinoma to the liver, right kidney, and large intestine.
