Nasolacrimal duct tumours in the era of endoscopic dacryocystorhinostomy: literature review

Abstract

AbstractBackground:Nasolacrimal duct tumours are rare and are often found inadvertently during dacryocystorhinostomy. Anecdotal case reports have been published, mostly in ophthalmology journals. Since the era of endoscopic dacryocystorhinostomy, such cases are more frequently encountered by ENT surgeons.Method:This paper reports a retrospective chart review of patients who underwent endoscopic dacryocystorhinostomy over the last 10 years in our dedicated epiphora clinic. It also provides a systematic literature review of nasolacrimal duct tumour cases published in English over the last 16 years.Results:Four of 525 endoscopic dacryocystorhinostomy procedures exposed a tumour (inverted papilloma, oncocytoma, lymphoma and solitary fibrous tumour). The literature review revealed 118 published case reports. Papilloma was the most frequently reported benign tumour and lymphoma was the most common malignant tumour.Conclusion:Since the advent of endoscopic dacryocystorhinostomy, tumours are being diagnosed relatively early when smaller in size. Because of the rarity of this condition, it is advisable that such cases are managed through a dedicated epiphora service framework.
