Pancreatic acinar cell carcinoma (ACC) is a rare malignant neoplasm that accounts for 1-2% of all pancreatic neoplasms. Here we report two cases of ACC and describe their clinical features, the therapies used to treat them, and their prognosis. The first patient was a 65-year-old woman who had an abdominal CT scan for a urinary infection. Fortuitously, a rounded and well-delimited corporeal pan...
متن کاملPapillocystic Variant of Acinar Cell Pancreatic Carcinoma
Acinar cell pancreatic carcinoma is a rare solid malignant neoplasm. Recent review of the literature showed occasional cases with papillary or papillocystic growth patterns, ranging from 2 to 5 cm in diameter. We report a large 10 cm pancreatic tumor with papillocystic pathology features involving the pancreatic head. The growth pattern of these tumors could be mistaken for intraductal papillar...

متن کاملDemonstration of kallikrein in a rat pancreatic acinar cell carcinoma.
Kallikrein was identified immunohistochemically and biochemically in a transplantable pancreatic acinar cell carcinoma of the rat. The concentration of immunoreactive kallikrein in tumor homogenates was the same as in the pancreas. Kallikrein in tumor cells exists as a proenzyme and is released into blood in high concentrations. The impact of the presence of a kallikrein-producing tumor on othe...
متن کاملA case of pancreatic acinar cell carcinoma metastatic to skin
We report a rare case of pancreatic acinar cell carcinoma with widespread metastases in a 68-year-old woman who presented with subcutaneous nodules as the initial symptom. Computed tomography showed a pancreatic mass with hepatic tumors and enlarged lymph nodes besides ring-enhanced subcutaneous nodules. Magnetic resonance diffusionweighted imaging detected the presence of lesions in other orga...
