ABSTRACT

Squamous cell carcinoma (SCC) is the most common malignancy of the oral cavity. Basaloid squamous cell carcinoma (BSCC), a rare variant of SCC, is a highly malignant tumor associated with high mortality rates. This report presents a rare case of exophytic BSCC arising at the posterior region of the tongue margin in a 74-year-old man. Excisional biopsy with a 10-mm safety margin around the base of the tumor was performed, and the wound was primarily sutured. The postoperative course was uneventful, with no local recurrence or metastasis. However, the patient died of cerebral infarction 4 years after operation. Key words: basaloid squamous cell carcinoma, exophytic tumor, tongue, oral, cavity
