A tissue mass in the floor of the mouth was found to be an unusual, exophytic squamous cell carcinoma. The patient also had synchronous hepatic metastasis from an occult primary adenocarcinoma. The case is discussed from the standpoint of the differential diagnosis of lesions that may appear as masses of the floor of the mouth. Individuals with one primary cancer are at increased risk for developing second malignancies which may be in either the same anatomic area or in other organ systems. This case report emphasizes the need for the clinician to periodically follow-up any patient with a history of malignancy.
口底的一个组织块被发现是一种罕见的外生性鳞状细胞癌。该患者还存在隐匿性原发性腺癌的同步肝转移。从可能表现为口底肿物的病变的鉴别诊断角度对该病例进行了讨论。患有一种原发性癌症的个体发生第二原发性恶性肿瘤的风险增加，第二原发性恶性肿瘤可能发生在同一解剖区域或其他器官系统。本病例报告强调临床医生需要定期对任何有恶性肿瘤病史的患者进行随访。
