Abstract

Papillary squamous cell carcinoma is a rare variant of squamous cell carcinoma. The predominant occurrence sites are the larynx, oropharynx and nasopharynx. We report a case of papillary squamous cell carcinoma of the buccal mucosa. A 76-year-old-man with the complaint of tumor of the left buccal mucosa was referred to our center. Intraoral examination showed a 30×20mm-sized well-circumscribed, papillary, elastic hard mass of the left buccal mucosa. No metastasis of the neck lymph nodes was detected. CT demonstrated a mass sized 28×16mm at the left buccal mucosa. MRI revealed no invasion of the tumor to the buccinator muscle. The patient underwent resection of buccal mucosal carcinoma. There was no evidence of recurrence 2 years after surgery.
