Abstract
Purpose: To report a case of extramedullary plasmacytoma in the lacrimal excretory system. Case summary: A 56-year-old female patient suffering from chronic epiphora for 1 year and having a non-tender, fixed palpable mass in the medial canthus of the eyelid visited the outpatient clinic. Orbital CT showed the non-enhancing mass was located along the right lacrimal sac and nasolacrimal duct and protruded into the nasal cavity. Biopsy was performed at the Otolaryngology Department. Based on histopathological examination, the mass was diagnosed as extramedullary plasmacytoma and the patient was treated with a total dose of 4500 cGy radiation (25 times in 1 month). After the 28-month follow-up period, the mass was not observed on Sinus CT and there was no recurrence. Additionally, no specific lesion was found during nasal endoscopy. Conclusions: We report a case of extramedullary plasmacytoma in the lacrimal excretory system successfully treated by radiation therapy. J Korean Ophthalmol Soc 2015;56(3):427-431
