A case of synchronous multiple primary carcinomas of the tongue mucoepidermoid carcinoma and lower gingival squamous cell carcinoma in the oral cavity

Abstract

We report a case of synchronous multiple primary carcinomas of the tongue mucoepidermoid carcinoma and lower gingival squamous cell carcinoma of a 60-years-old woman. She was referred to our department with the chief complaint of a mass in the underside of tongue, which had persisted for 1 year. The mass had clear border and mobility and we found white lesion on the left lower gingiva. Pathological examination of a biopsy specimen revealed mucoepidermoid carcinoma in tongue and well differentiated squamous cell carcinoma in lower gingiva. Tumor resection was performed under general anesthesia. The patient has been well and free from the disease for 5 years.
