Primary small cell carcinoma of the esophagus with ectopic gastrin production. Report of a case and review of the literature.
A case of primary small cell carcinoma of the esophagus in which extensive hormonal studies could be performed is reported. The tumor was considered as a neuroendocrine tumor because the tumor cells showed intracytoplasmic argyrophilia, neurosecretory granules, and positive stain for neuron-specific enolase with Grimelius stain, electron microscopy, and immunohistochemistry, respectively. Furthermore, the tumor was regarded as a gastrin-producing tumor because of positive stain for gastrin in the tumor cells. The present case is the first case of primary small cell carcinoma of the esophagus with ectopic gastric production.
