title: Primary gastric plasmacytoma of rapid growth presenting with upper gastrointestinal bleeding.
abstract: We report a new case of primary gastric plasmacytoma. The presenting symptoms was upper gastrointestinal bleeding, and the diagnosis was made preoperatively by means of gastroscopically obtained biopsy material. The demonstration of a single type of IgA-kappa immunoglobulin in plasma cells infiltrating the gastric antrum is considered conclusive evidence of its neoplastic nature. Endoscopically, the gastric plasmacytoma progresses from a benign antral ulcer (0.5 cm in diameter) to an ulcerated mass (7 cm in diameter) in an 8-wk period, suggesting rapid tumoral growth of a kind not described in the revised literature.
