눈물주머니에서 기원한 반전성 유두종 1예

초록

Inverted papillomas are benign but invasive tumors with malignant potential characterized bya high recurrence rate. Although most cases arise from the nasal wall and paranasal sinuses,inverted papillomas originating from the nasolacrimal system have been rarely reported. Wedescribe a rare case of an inverted papilloma in the left nasal cavity, which originated fromthe lacrimal sac in a 40-year-old female who had a medical history of endoscopic dacryocys-torhinostomy at the department of ophthalmology. At first, it was believed to be an invertedpapilloma simply occurring in the nasal cavity, but after several recurrences, it was found tooriginate from the lacrimal sac. All intranasal lesions and the involved lacrimal sac were re-moved through cooperative surgery between department of otolaryngology and ophthalmology. This case illustrates the importance of including nasolacrimal system in differentiating the origin of inverted papilloma.
