Maxillary sinus carcinoma: The only symptom was neck lymph node swelling

The main symptoms of maxillary sinus carcinoma are related to the local progression, and known to have less cervical lymph node metastasis. However, like the present case, there is a rare case that has no symptom and organic features associated with the local mass. With the best use of advanced diagnostic technique, e.g., FDG-PET, we could diagnose and treat atypical maxillary sinus carcinoma patients.
