title: Nasolacrimal duct obstruction caused by oncocytic carcinoma.
abstract: Here, we report an extremely rare case of acquired nasolacrimal duct obstruction caused by oncocytic carcinoma. A 64-year-old man presented to the hospital complaining of epiphora and left-side nasal obstruction. Ophthalmic and otolaryngology examination revealed a left lacrimal duct obstruction caused by a mass in the left nasal cavity and lacrimal drainage system. The mass was removed and confirmed as an oncocytic carcinoma. Nine months after surgery, without adjuvant radiotherapy, a left orbital mass was observed and the patient underwent reoperation. The mass proved to be recurrent oncocytic carcinoma. The patient underwent adjuvant radiotherapy to eradicate any residual tumor and the patient remains tumor-free one year post-radiotherapy.
