Abstract

Lymphoepithelial carcinoma is a rare type of undifferentiated carcinoma, characterized by atypical epithelial cells surrounded by a reactive lymphoplasmacytic infiltrate. We report a case of sinonasal lymphoepithelial carcinoma arising in the left maxillary sinus in an 80-year-old Caucasian male patient. The lesion had invaded the adjacent lateral wall of the nasal cavity appearing on the palate as a painful swelling. There was no evidence of tumor involvement from the nasopharynx and larynx assessment and no swollen cervical lymph nodes were noticed on the head and neck imaging examination. An incisional biopsy from the oral cavity, as well as an endoscopic biopsy of the neighboring nasal mass were performed. The histopathological and immunohistochemical analysis of both specimens showed identical features and a common diagnosis of sinonasal lymphoepithelial carcinoma was rendered. In conclusion, oral swellings located on the palate may be associated with maxillary sinus malignancies. Thus, the clinician should include in the differential diagnosis not only primary oral carcinomas, but also malignant neoplasms arising from neighboring anatomic sites.
