Abstract

Fibromyxomas are uncommon, tenaciously infiltrative neoplasms that infrequently appear in the facial bones and paranasal sinuses. The neoplasms are slow growing and result in expansion of the surrounding bony cortices. In the present study, we report an extremely rare case of antrochoanal fibromyxoma that occluded the ostiomeatal complex and originated from the maxillary sinus inferior wall. Initially, the neoplasm was suspected to be a nasal polyp. However, after endoscopic sinus surgery, the neoplasm was diagnosed as fibromyxoma based on histopathology.

Key Words: Fibromyxoma;Antrochoanal polyp;Nasal polyp
