<b>First canine case of nontraumatic hemoperitoneum secondary to pancreatic acinar cell carcinoma: Successful surgical management</b>

This report is the first documented case describing successful surgical management of nontraumatic hemoperitoneum secondary to pancreatic acinar cell carcinoma in a dog. Histopathological evaluation confirmed a moderately well-differentiated pancreatic acinar cell carcinoma. This case suggests that timely diagnosis and intervention may improve outcomes in patients with hemorrhagic presentations of pancreatic neoplasia.
