Abstract

We present the cytologic features of a case of solid and papillary neoplasm of the pancreas. Cytologically, the tumor was composed of a monotonous population of polygonal cells containing eccentrically located round nuclei with one or two distinct small nucleoli and a finely stippled chromatin pattern. The tumor cells were similar to those of the islet cell tumor and showed isolated loosely aggregated and solid sheets or large cell clumps. The large cell clumps revealed a branching papillary structure containing fibrovascular central core, which is characteristic histologic feature of solid and papillary neoplasm of the pancreas. This case was confirmed by tissue examination including histochemical, immunohistochemical and electron microscopical studies. Ultrastructurally, the tumor cells contained a few membrane-bound electron dense granules.
