摘要

Schwannomas of the nose and paranasal sinuses originating from the infraorbital nerve is extremely rare accounting for less than 4% of benign peripheral nerve sheath tumors of the head and neck region. We present the case of a 40-year old female who presented to our ENT outpatient department with 3 months history of swelling on the right nasomaxillary area and nasal obstruction on right side. On examination revealed a swelling which is of approximately 3x1.5 cm size, firm, circular and non tender. Pre operative computed tomography demonstrated soft tissue mass involving right lateral wall of nose without bony destruction. Tumor was resected via sub labial approach and on histopathological examination, it presented as a typical manifestation of schwannoma with Antoni A area with Verocay body. No recurrence was seen in the follow-up period of 1 year.
