Abstract:
Purpose:To report a case of oncocytic and inverted Schneiderian papilloma originating from the lacrimal sac.Case summary: A 70-year-old male presented with a 5-year history of bilateral epiphora. Best-corrected visual acuity was 0.9 in the right eye and 1.0 in the left eye, and intraocular pressure was 12 mmHg in the right eye and 14 mmHg in the left eye. The findings of nasolacrimal duct probing, the irrigation test, and dacryoscintigraphy suggested partial obstruction of the right nasolacrimal duct. Computed tomography and magnetic resonance imaging revealed a mass measuring approximately 2.5 cm in the right lacrimal sac. Surgical excision of the mass was planned in collaboration with the otolaryngology department, followed by histopathologic examination of the resected specimen. The otorhinolaryngology team removed the lacrimal sac mass endoscopically through the nasal cavity and submitted the specimen for histopathologic analysis. Subsequently, endoscopic dacryocystorhinostomy was performed. Postoperatively, the patient’s epiphora resolved, and histopathologic evaluation confirmed the diagnosis of oncocytic and inverted Schneiderian papilloma.
Conclusions:Schneiderian papilloma can originate from the nasolacrimal duct and should be considered in the differential diagnosis of patients presenting with epiphora.
