Recurrent conjunctival papilloma causing nasolacrimal duct obstruction.

ABSTRACT

We treated two patients who had recurrent conjunctival papillomas that invaded the nasolacrimal sac and caused complete canalicular and nasolacrimal duct obstruction. The ophthalmologist should be aware of the possibility of a conjunctival papilloma invading the lacrimal sac when treating patients with conjunctival papillomas. Excision should be complete, and adjunctive therapy such as cryotherapy should be considered to reduce the chance of tumor recurrence.
