A case of maxillary cancer manifested as a maxillary mucocele

Abstract

A 63-year-old man with maxillary cancer which presented as a maxillary mucocele is herein reported. The CT and MRI findings showed a cystic lesion in the right maxillary sinus. Endoscopic sinus surgery was performed and a pathological evaluation revealed the existence of poorly differentiated squamous cell carcinoma in the right maxillary sinus. The literature related to cystic cancer in the paranasal sinuses was also briefly reviewed.
