Summary
Primary orbital intraosseous hemangiomas are rare vascular tumors. Surgical excision is effective for most patients, though some may require repeat operations due to tumor progression.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Primary orbital intraosseous hemangiomas are exceptionally rare benign vascular tumors.
- Only 16 cases have been previously documented in medical literature.
Observation:
- The study presents five new cases of orbital intraosseous hemangioma.
- Patients aged 49–77 years presented with painless or mildly tender nodular lesions.
- Ophthalmic symptoms were generally minimal, with one case showing initial nasolacrimal obstruction.
Findings:
- Four out of five patients achieved positive outcomes following surgical tumor removal (complete or partial excision).
- One patient experienced tumor progression after initial partial resection, necessitating a second surgery.
- Review of 16 prior cases provides further insight into the lesion's characteristics.
Implications:
- Complete or partial tumor excision appears to be an effective treatment for orbital intraosseous hemangioma.
- The potential for tumor progression highlights the importance of vigilant follow-up after surgical management.
- Understanding the natural history and pathology of this rare vascular tumor is crucial for accurate diagnosis and treatment planning.
