MARTI-GELONCH, Laura et al. Unexpected diagnosis in a patient with suspected GIST: gastric infiltration due to multiple myeloma. Cir. cir. [online]. 2020, vol.88, suppl.2, pp.90-93.  Epub 08-Fev-2022. ISSN 2444-054X.  https://doi.org/10.24875/ciru.20000566.

Multiple myeloma is characterized by medullary neoplastic proliferation of plasma cells producing monoclonal immunoglobulin. A small percentage of patients have extramedullary involvement in form of plasmacytoma, the most common location being the upper respiratory tract. Gastrointestinal involvement is rare and the associated symptoms will depend on the location, extent and mechanism of infiltration. Gastric involvement presents an appearance and symptoms similar to other lesions, so a histological diagnosis is necessary for proper treatment. This article presents the case of multiple myeloma with gastric involvement.
