Extramedullary plasmacytoma involving rectum: A case report and literature review

Abstract:
Extramedullary plasmacytoma (EMP) of the gastrointestinal tract is an extreme rarity. Clinical manifestations of EMPs are varied, depending on the position and progress of tumor. Here we report a case of an EMP involving rectum in an 80-year-old, male patient with a change of bowel habit. Computed tomography scanning confirmed a circumscribed, iso-attenuating mass with the obvious heterogeneous enhancement. Patient received the surgical resection by laparoscope and the plasmacytoma was finally confirmed by the pathology. Furthermore, we made a literature review about the EMP of gastrointestinal tract to get the further study. Finally, we found out there is no specificity in imaging examination. Diagnosis of EMP still depends on the histopathology.
Insights
Extramedullary plasmacytoma (EMP) is a rare gastrointestinal tumor. This case highlights rectal EMP diagnosis, emphasizing histopathology
Area of Science:
- Gastroenterology
- Oncology
- Surgical Pathology
Background:
- Extramedullary plasmacytoma (EMP) of the gastrointestinal tract is exceptionally rare.
- Clinical presentations of EMP vary based on tumor location and progression.
Observation:
- A case report details an 80-year-old male with rectal EMP presenting with altered bowel habits.
- CT imaging revealed a circumscribed mass with heterogeneous enhancement.
Findings:
- Surgical resection via laparoscopy was performed, with pathology confirming the plasmacytoma.
- A literature review indicated no specific imaging characteristics for gastrointestinal EMP.
Implications:
- Diagnosis of gastrointestinal EMP relies heavily on histopathological examination.
- This case contributes to understanding the rare occurrence and diagnostic challenges of EMP in the rectum.
