Summary
A solid and cystic tumor (SCT) of the pancreas occurring in a 35-yr-old male is reported. Cut sections of the specimen revealed a solid, ill-defined mass measuring 2.5×2.3×2.0 cm, without cystic or necrotic changes. Histologically, the solid tumor consisted of small, round acidophilic cells invading the surrounding pancreatic parenchyma. The tumor cells were positive for α-1-antitrypsin and neuron-specific-enolase. Ultrastructural studies revealed clear nuclei with no zymogen, but immature secretory granules in the cytoplasm of the tumor cells, which had a junctional complex-like structure. These findings were consistent with the so-called solid and cystic tumor of the pancreas. There was neither a capsule surrounding the tumor nor a papillary structure, known to be characteristic findings of the SCT tumor. The small tumor reported in the present article might represent an early-stage SCT of the pancreas.
