Abstract
Ten cases of the rare solid and cystic pancreatic tumors are presented. All except one occurred in young women (mean age, 25 +/- 9.2 years). The large neoplasms were evenly distributed across the pancreas; in one case, metastasis occurred; all other cases were free from disease after complete resection. Histologic hallmarks of solid and cystic neoplasms were papillary growth, large intracytoplasmic granules, and immunoreactivity with alpha 1-antitrypsin, alpha 1-antichymotrypsin, phospholipase A2, and neuroendocrine markers (neuron-specific enolase [NSE], synaptophysin). This suggests both endocrine as well as exocrine differentiation.
