Lacrimo-auriculo-dento-digital syndrome: A case report and literature review.

We report a healthy 18-year-old male Saudi with bilateral agenesis of the lacrimal puncta and canaliculi associated with large dacryocystocele on the right side without tearing or inflammation, detected in conjunction with other characteristic features of lacrimo-auriculo-dento-digital dysplasia syndrome. Computed tomography scan indicated that dacryocystoceles were bilateral and asymmetrical, with large dimensions at the right side and associated to a right side maxillary sinus mucocele. The right dacryocystocele was surgically removed, and the histology indicated characteristics of the lacrimal sac. The liquid content of the dacryocystocele was negative for microbes. The atypical mucocele in the maxillary sinus disappeared after dacryocystocele removal probably, due to recovery of sinus drainage.
