KEYWORDS Summary Oral cancer is one of the six most frequently occurring cancers. The Squamous cell most common type of oral cancer is squamous cell carcinoma (SCC). Squamous cell carcinoma; carcinoma is a malignant neoplasm of mucosal origin. The most common site of Poor oral hygiene and intraoral squamous cell carcinoma is the lateral border and ventral surface of the dental trauma; tongue. The cause of oral SSC is multifactorial. In this paper, a case of SCC in the Tongue tongue due to poor oral hygiene and dental trauma is presented. The lesion was ini- tially described by the patient as a dental trauma but biopsy-proven SCC on histo- pathologic evaluation. The emphasis is on early diagnosis and correct treatment planning which can affect the prognosis. c 2005 Elsevier Ltd. All rights reserved.

Discussion

More than 90% of all oral malignancies are squa- mous cell carcinomas.7 SCC of the tongue was the cancer seen most frequently (27.6%), followed by cancer of the oropharynx (22.8%), lip (16.5%), floor of the mouth (14%), gingiva (9.1%) hard palate (4.1%), and buccal mucosa (3.5%) in a report cover- ing the years between 1983 and 1993 in America.11 The most common site of intraoral carcinoma involvement is the tongue, usually the posterior lateral ant ventral surfaces.7 In our patient, SSC was posterior lateral border of the tongue. 112 R.
