title: Inverted papilloma of lacrimal sac invading into the orbit: case report and review of literature.
abstract: Inverted papilloma (IP) is a sinonasal tumor of benign etiology with local invasion and malignant potential. IP arising in lacrimal sac invading the orbit is extremely rare with only one case reported so far. The presented case appears to be the second such case reported in the literature. A 60-year-old Caucasian male presented with a medial canthal mass and epiphora. Incisional biopsy confirmed a transitional neoplasm. The lesion was completely excised enbloc with clear margins by using a Weber-Ferguson incision; orbital clearance and nasolacrimalfossa clearance was achieved via a medial maxillectomy. Enbloc resection of orbital and nasolacrimal parts of the tumor with clear margins is recommended.
