PRIMARY GASTRIC PLASMACYTOMA OF RAPID GROWTH PRESENTING WITH UPPER GASTROINTESTINAL-BLEEDING

We report a new case of primary gastric plasmacytoma, The presenting s ymptom wass upper gastrointestinal bleeding, and the diagnosis was mad e preoperatively by means of gastroscopically obtained biopsy material . The demonstration of a single type of IgA-kappa inmunoglobulin in pl asma cells infiltrating the gastric antrum is considered conclusive ev idence of its neoplastic nature. Endoscopically, the gastric plasmacyt oma progresses from a benign antral ulcer (0.5 cm in diameter) to an u lcerated mass (7 cm in diameter) in an 8-wk period, suggesting rapid t umoral growth of a kind not described in the revised literature.
