The objective of this paper is to report a case of lacrimal apocrine adenocarcinoma which presented as chronic dacryocystitis. A 62-year-old male was referred by his primary ophthalmologist for evaluation of chronic dacryocystitis of the right eye for 3 months. Biopsy showed a rare and aggressive type of cancer: apocrine adenocarcinoma of the nasolacrimal sac and paranasal sinuses. The patient was treated with orbital exenteration followed by chemoradiation therapy. Apocrine adenocarcinoma, a rare tumor of the eyelid glands, can masquerade as chronic dacryocystitis.
