Abstract

Inverted papilloma (IP) originating primarily in the nasolacrimal duct (NLD) is considered very rare. Most of IP cases arising from the ethmoid region, lateral wall of nasal fossa and maxillary sinus. It is an aggressive neoplasm characterized by high recurrence rates and prone towards malignant transformation, albeit it’s a benign neoplasm histologically. IP of NLD may present as non progressive medial canthal swelling, masquerading as more common conditions such as dacryocystitis, or other primary acquired NLD obstruction. Here, we report a case of a 70-year-old gentleman, presented with a swelling in his right medial canthal region for a 3-month duration, associated with tender on palpation and unilateral epiphora. Nasoendoscopy showed a granulation tissue arising from the right Hasner valve and biopsy revealed IP features. Radiological imaging revealed an enhancing soft tissue lesion arising from the right NLD associated with a mild expansion of the duct but no bony erosion seen. He underwent an open right medial maxillectomy with right dacryocystectomy via lateral rhinotomy approach, and the patient made an uneventful recovery with normal visual acuity and intact eye movements.
