[Show abstract][Hide abstract] ABSTRACT: There has been an increase in the incidence of carcinoma of the tongue, particularly among alcohol and tobacco non-users. However, the number of studies that would allow a better understanding of etiological factors and clinical features, particularly in the Portuguese population, is very limited. This study was based on patients with squamous cell carcinoma of the anterior two thirds of the tongue that were treated at the Department of Head and Neck Surgery of the "Instituto Portugues de Oncologia de Lisboa - Francisco Gentil" (IPOLFG) in Lisbon, Portugal, between January 1, 2001 and December 31, 2009. The patients were divided in alcohol and tobacco users and non-users in order to evaluate the differences between these 2 groups based on gender, age, tumor location, denture use, and tumor size, metastasis and stage. Of the 354 cases, 208 were users and 146 were non-users. The main location in both groups was the lateral border of the tongue. Denture use showed no significant effect in both study groups. It was possible to conclude that patients who did not drink or smoke were older and presented with smaller tumor size, lower incidence of ganglion metastasis and lower tumor stage compared with alcohol and tobacco users.
[Show abstract][Hide abstract] ABSTRACT: The squamous cell carcinoma is defined as a malignant neoplasia originated on the stratified paved epithelium. It is the most common malignant neoplasia in the mouth, representing 90% of all oral cancers. Approximately 95% of these carcinomas are manifested on ages above 40, the average age on the masculine sex is 60 and on the feminine sex 70. Man/Woman ratio is 3:1 but on the last decade, a chance on this proportion has been noticed, due to an increase on tobacco use by women.Objective
The aim of this work is to present a clinical case of an “innocent” looking ulcer on the right edge of the tongue.Clinical caseA patient presenting an ulcer in the tongue is studied clinically and histopathologically, in order to reach the right diagnose of the lesion. The clinical examination and the histopathological analysis led to the diagnosis of squamous cell carcinoma.Conclusions
Squamous cell carcinoma is relatively easy to diagnose in the mouth, because of its accessibility to clinical and histopathological examination. The most important thing is to reach an early diagnose and starting the best treatment (usually surgical) as soon as possible.
