title: Gastric adenocarcinoma concurrent with paravertebral plasmacytoma: A case report.
abstract: Here, we report the case of a 77-year-old male patient who was revealed to have an unsuspected case of gastric adenocarcinoma with paravertebral plasmacytoma following biopsy. Plasmacytoma may be classified into two main groups: Multiple myeloma and plasmacytoma without marrow involvement. It comprises isolated plasmacytoma of the bone and extramedullary plasmacytoma. Extramedullary plasmacytoma (EMP) accounts for 3% of all plasmacytomas; however, ~80% are located in the upper respiratory tract and upper gastrointestinal tract. It occurs extremely rarely in paravertebral areas. Case reports of EMP and other types of malignant tumor occurring at the same time have not been identified in searches of the literature. In the present study, we describe the diagnosis and treatment process of a case of gastric adenocarcinoma concurrent with paravertebral plasmacytoma. It may be helpful for early clinical diagnosis and treatment of such cases.
