Abstract:
Acinar cell carcinoma (ACC) of the pancreas is a rare malignancy making up approximately 1% of pancreatic non-endocrine malignant tumors. The common finding on computed tomography is a solitary, well-defined, heterogenous hypodense mass with enhancing capsule. ACC is a highly cellular tumor with minimal stroma and a lack of stromal desmoplasia. The accurate diagnosis of ACC cannot typically be done by histology alone but rather requires immunohistochemical staining or electron microscopy for the identification of pancreatic enzymes and zymogen granules. ACC has been considered a cancer with a poor prognosis due to frequent metastasis, a high recurrence rate, and low respectability. Surgical resection is the treatment of choice that can lead to long-term survival. ACC has a better prognosis than ductal carcinoma of the pancreas, but a worse prognosis compared to islet cell carcinoma. We report two cases of ACC with 5-year survival after surgical resection.
