Rapports de cas de santé bucco-dentaire

Tongue cancers are the most frequent types of malignant tumors of the oral and maxillofacial regions, and their prognosis is usually worse than that of other oral cancers. Most tongue cancers occur on the lateral borders of the tongue, and their occurrence on the tip of the tongue is rare. Moreover, squamous cell carcinomas rarely show pedunculated growth, in contrast, oral verrucous carcinomas, which show external growth, are a distinct type of squamous cell carcinoma. This report describes a rare case of pedunculated squamous cell carcinoma on the tip of the tongue in a 68-year-old woman. This pedunculated tumor with induration, tenderness, and an irregular surface was approximately 35 mm × 35 mm in size and could easily hemorrhage. The lesion was histopathogically diagnosed as a well-differentiated squamous cell carcinoma. A lichen planus-like white lesion was adjacent to the left of the tumor was pathologically diagnosed as a carcinoma in situ.
