Schneiderian papillomas are benign tumours, with an aggressive nature. A case with a recurrent Schneiderian papilloma of the nasolacrimal sac, who underwent an external dacryocystorhinostomy (DCR) with irrigation of the nasolacrimal system with 0.02% mitomycin C (MMC), is presented at 18 months follow-up. External DCR using MMC, as an adjuvant therapy, is a novel approach to the treatment of Schneiderian papilloma of the nasolacrimal tract. It allows preservation of function, compared with the conventional treatment of dacryocystectomy.
