Summary
Primary extramedullary plasmacytoma (EMP) is a rare duodenal tumor. Combined surgery and chemotherapy achieved remission, but EMP later disseminated, highlighting its complex nature.
Area of Science:
- Oncology
- Gastroenterology
Background:
- Primary extramedullary plasmacytoma (EMP) is a rare plasma cell malignancy occurring outside the bone marrow.
- EMP typically affects the upper airway/oral cavity, with only 10% found in the gastrointestinal tract, and just 8 duodenal cases reported.
Observation:
- A case study of a 53-year-old male with duodenal EMP initially misdiagnosed as a desmoid tumor.
- The patient underwent combined surgery and chemotherapy.
Findings:
- Complete remission was achieved for 2 years post-treatment.
- Tumor dissemination occurred in the testis, mandibular bone, and ribs after the initial remission.
Implications:
- Extramedullary plasmacytoma (EMP) presents a diagnostic challenge for intra-abdominal tumors, often requiring postoperative immunohistochemical confirmation.
- Combined surgical and chemotherapeutic treatment strategies show promise for managing EMP, though long-term surveillance for recurrence or metastasis is crucial.
