Lacrimal canalicular papillomatosis.

Three new cases of lacrimal canalicular papillomatosis are reported and the total of 12 cases in the literature reviewed. They present with epiphora or a local mass. Multiple recurrences over many years is characteristic. A minority have papillomata of the conjunctiva or lacrimal sac. Histopathological examination shows a benign papilloma with a fibrovascular stalk. Treatment was either multiple excision or cryotherapy, but neither affected the rate of occurrence. A viral aetiology is postulated in some cases.
