Maxillary sinus carcinoma initially mistaken for morpheaform basal cell carcinoma

Abstract

Squamous cell carcinoma (SCC) of the maxillary sinus is the most common malignant neoplasm of the paranasal cavity. The most frequent initial symptoms are swelling of the cheek, nasal obstruction, epistaxis, and nasal discharge. Herein, we report the case of a 62-year-old Korean male who initially presented with a whitish irregular depressed plaque with an indurated border in his left cheek. After a several-week delay in diagnosis, he was eventually diagnosed with maxillary sinus carcinoma.
