Summary
Malignant hemangiopericytoma can recur years after surgery, even in the liver. Early detection of recurrent hemangiopericytoma is challenging due to lack of specific markers, suggesting Positron Emission Tomography (PET) may aid surveillance.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Hemangiopericytoma is a rare tumor, infrequently originating in the peritoneal cavity.
- Malignant hemangiopericytoma exhibits a notable propensity for late recurrence following resection.
Observation:
- A 60-year-old woman presented with a recurrent liver hemangiopericytoma 7 years post-omentum resection.
- Imaging revealed a large, necrotic, hypervascular liver tumor consistent with recurrence.
- The patient had a history of malignant hemangiopericytoma and suboptimal post-operative follow-up.
Findings:
- Right trisegmentectomy successfully resected the recurrent liver hemangiopericytoma.
- Pathological examination confirmed the diagnosis of recurrent hemangiopericytoma.
- Recurrent hemangiopericytoma lacks specific tumor markers and can present with diverse recurrence sites, complicating early detection.
Implications:
- Positron Emission Tomography (PET) is proposed as a valuable tool for detecting recurrent hemangiopericytoma.
- This case highlights the importance of vigilant surveillance for malignant hemangiopericytoma recurrence.
- Understanding the behavior of recurrent hemangiopericytoma post-resection is crucial for patient management.
