Abstract
Purpose: Sclerosing lipogranuloma is an unusal benign condition of the genitalia following injections into the genitalia with exogenous paraffin or mineral oil. A few cases have been reported in which sclerosing lipogranuloma of the lid was caused by paraffin-containing ointment plugs after the endonasal sinus surgery. A 52-year-old man presented with a painless hard mass of the right lower lid after the MRI scan at the Ophthalmology department. Nine months before, he had undergone right maxilla sinus surgery through the oral incision. And he was also gotten nasal packing with Vaseline gauze after the surgery. Methods: The round shaped two masses in the Right lower lid were approximately $1.0{\times}1.0cm$ in size. There were no size or color change, bleeding and ulceration. The MRI scan showed a suspicious part of an abscess of benign tumor. Also, He was planned cyst remove through the endonasal surgery due to the mucoid cyst in the right maxillary sinus in the ENT dept. Under the general anesthesia, the patient underwent surgical excision through a subcilliary incision with endonasal sinus surgery. The masses were in deep subcutaneous orbital fat with no connection with right maxillary sinus. Results: The masses were excised $2.1{\times}0.7cm$ in size including surrounding necrotic fatty tissue. Histopathological diagnosis was 'sclerosing lipogranuloma' due to paraffin or similar substance with fat necrosis and cystic change. This tissue was positive in PAS, S-100, CD68 reaction. Conclusion: It is extremely rare to find a granulomatous orbital lesion arising to a endonasal surgery. In conclusion, if sclerosing lipogranuloma is suspected excisional biopsy should be undertaken. Surgery should be reserved for recurrent or refractory cases when steroids have failed as first-line treatment at the 6-month follow-up examination, There was no complication or recurrence.
