Fibro-inflammatory pseudotumour in the maxillary sinus
Singapore Medical Journal
|December 1, 1993
Summary
A rare fibro-inflammatory pseudotumor in a child's maxillary sinus mimicked cancer but was benign. Surgical removal and steroid therapy led to a full recovery with no signs of recurrence.
Area of Science:
- Otolaryngology
- Pathology
- Pediatric Oncology
Background:
- Fibro-inflammatory pseudotumors are rare benign lesions that can occur in various locations, including the sinonasal tract.
- Distinguishing these lesions from malignant tumors is crucial for appropriate patient management.
Observation:
- A 13-year-old Chinese girl presented with proptosis and imaging findings suggestive of malignancy in the right maxillary sinus.
- Histopathological examination revealed a benign fibro-inflammatory pseudotumor, not a malignancy.
Findings:
- The patient underwent a Caldwell-Luc operation for tumor removal.
- Prolonged steroid therapy was administered post-operatively.
Implications:
- This case highlights the importance of histopathological diagnosis in differentiating benign sinonasal masses from malignancies.
- Successful management with surgery and steroids suggests a favorable prognosis for sinonasal fibro-inflammatory pseudotumors.
- Early diagnosis and treatment can prevent unnecessary aggressive therapies for benign conditions.
