Acinar cell carcinoma of the pancreas: a case report

Acinar cell carcinoma (ACC) of the pancreas is rare and usually presents as a metastasizing tumor with poor prognosis in elderly patients with non-specific symptoms. We describe a case of pancreatic acinar cell carcinoma with peritoneal spread and multiple liver metastases. Abdominal sonography showed a well-marginated echogenic mass with a large central anechoic necrotic portion; CT scanning showed a large mildly enhanced lobulated mass with a low attenuation center and thin rim-like capsular enhancement. Irregular peritumoral peritoneal extension with multiple small low attenuation necrotic areas was also noted. Multiple small well-defined metastatic nodules showing low attenuation were scattered in the liver.=20
