Summary
Intra-abdominal inflammatory myofibroblastic tumors are rare in children. Complete surgical excision is crucial for preventing recurrence, as these tumors can mimic malignancy.
Area of Science:
- Pediatric Oncology
- Surgical Pathology
Background:
- Inflammatory myofibroblastic tumors (IMTs), also known as inflammatory pseudotumors, are uncommon neoplasms.
- Intra-abdominal IMTs in pediatric patients are particularly rare, with limited case descriptions in existing literature.
Observation:
- This study details three pediatric cases of intra-abdominal IMTs.
- Presentations varied, including fever, anemia, abdominal mass, and chronic duodenal obstruction, often accompanied by significant weight loss.
- Surgical findings revealed large fibrous tumors (7-18 cm) originating from various intra-abdominal structures.
Findings:
- Histological examination, including intraoperative frozen sections, can be challenging and may lead to misdiagnosis, such as mistaking IMT for sarcoma.
- Complete surgical excision is the primary treatment goal.
- Tumor rupture during surgery in one case resulted in recurrent tumor nodules, highlighting the importance of meticulous surgical technique.
Implications:
- The rarity and potential for misdiagnosis underscore the need for high clinical suspicion for intra-abdominal IMTs in children.
- Accurate preoperative diagnosis and complete surgical resection are essential for optimal patient outcomes and preventing local recurrence.
- Further research into the diagnostic and therapeutic strategies for pediatric intra-abdominal IMTs is warranted.
