Summary
Psammomatoid ossifying fibroma (POF) is a rare fibro-osseous lesion. This case highlights successful endoscopic removal of a POF in the orbit and sinonasal tract, with no recurrence after five years.
Area of Science:
- Oral and Maxillofacial Pathology
- Otorhinolaryngology
- Ophthalmology
Background:
- Psammomatoid ossifying fibroma (POF) is a rare, benign fibro-osseous neoplasm.
- POF typically affects the craniofacial bones, with a predilection for the jaws.
- This subtype is characterized by psammoma bodies within the fibrous stroma.
Observation:
- A case report of a 13-year-old female with a POF involving the orbit and sinonasal tract.
- The diagnosis was established through a combination of histological, radiological, and clinical assessments.
- The lesion presented a diagnostic challenge due to its unusual location.
Findings:
- Complete surgical excision using endoscopic nasal surgery was performed.
- Histopathological examination confirmed the diagnosis of psammomatoid ossifying fibroma.
- Post-operative follow-up revealed no symptoms or tumor recurrence at five years.
Implications:
- Endoscopic endonasal surgery is a viable and effective treatment for sinonasal and orbital POF.
- Early diagnosis and complete resection are crucial for favorable outcomes.
- This case expands the understanding of POF presentation and management in pediatric patients.
