A case of squamous cell carcinoma arising in the midline of the dorsum of the tongue

Abstract

Primary carcinoma arising in the dorsum of the tongue is very rare and may be erroneously diagnosed as a benign lesion.
We present a case of squamous cell carcinoma of the dorsum of the tongue in a 49-year-old man. Intraoral examination revealed a tumor measuring 41×30×7 mm in the midline of the dorsum of the tongue. A biopsy was performed, and the diagnosis was squamous cell carcinoma. After preoperative chemotherapy, total resection of the tumor was performed. During about 1 year of follow-up, there has been no sign of recurrence or metastasis.
