 A man in his 70s, with a biopsy diagnosis of extramedullary plasmacytoma(immunoglobulin Gκ type)in the nasal sinus, underwent PET-CT(positron emission tomography-computed tomography), which revealed a giant plasmacytoma in the sinus and a localized accumulation on the sternal stalk. No lesion was found in the bone marrow, and the patient was diagnosed with multiple plasmacytoma. Three months following chemotherapy, another PET-CT, performed to observe the extent of the therapeutic effect, revealed multiple gastric lesions. Further evaluation using esophagogastroduodenoscopy displayed multiple reddish, elevated subepithelial or 0-IIa+IIc tumor-like lesions approximately 10mm in diameter, with depressions and erosions in the center. These lesions occurred primarily in the greater curvature of the gastric body and fornix. The histologic examination of the gastric lesion biopsies indicated a similarity of the lesions with the sinus plasmacytoma. Hence, the patient was diagnosed with diffuse gastric plasmacytoma involvement that mimicked a metastatic gastric tumor.
