Summary
Malignant triton tumor (MTT), a rare peripheral nerve sheath tumor, can occur in the pelvis. This case report details the diagnosis and surgical resection of a pelvic MTT in a male patient.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Malignant triton tumors (MTTs) are rare malignant peripheral nerve sheath tumors (MPNSTs) characterized by rhabdomyoblastic differentiation.
- MTTs typically occur in the head, neck, extremities, and trunk, with rarer documented instances in the buttock, mediastinum, and retroperitoneum.
Observation:
- A 47-year-old male presented with right flank pain and hematuria in July 2019.
- Imaging revealed a large pelvic mass located below the peritoneal reflection.
Findings:
- Surgical exploration and complete resection of the pelvic mass were performed.
- Pathological examination confirmed the mass as a malignant triton tumor (MTT).
Implications:
- This case expands the known anatomical distribution of MTTs to include the pelvis.
- Highlights the importance of considering rare diagnoses in the differential for pelvic masses.
- Contributes to the understanding of MTT presentation and management.
