Summary
Orbital dermoid tumors, rarely found within the lateral rectus muscle, were surgically removed in two patients. This case report highlights an unusual location for these orbital tumors.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Orbital dermoid tumors are typically found in the superior temporal quadrant.
- This report details two rare cases of orbital dermoid tumors located within the lateral rectus muscle.
Observation:
- Imaging revealed cystic masses within the lateral rectus muscle belly.
- Surgical excision confirmed well-circumscribed dermoid cysts.
Findings:
- Histopathology confirmed dermoid cysts in both patients.
- Postoperative resolution of diplopia and proptosis was observed.
- One patient exhibited unusual subconjunctival fat droplet deposition.
Implications:
- This presentation expands the differential diagnosis for enlarged extraocular muscles.
- Highlights the importance of considering unusual locations for orbital tumors.
