Abstract
The aim of this work is to present a case of a 74-year-old man who visited the Oral Medicine Department, Dentistry College, at the Catholic University of Cordoba with a gum lesion involving the lower incisors and the left canine. During oral examination, a gingival mass with an ulcerated surface of 6 months’ duration was noted. The lesion had a history of painless growth and displayed no dental mobility, however, it did exhibit a slight tendency to bleed. The patient was born and lived in a village near Cordoba, Argentina, which is characterized by arsenic contamination of groundwater. Classic risk factors for oral cancer such as tobacco consumption and alcohol were not found. Oral squamous cell carcinoma was diagnosed after an incisional biopsy. Arsenic, classified by the International Agency for Research on Cancer as a human chemical carcinogen, is present in groundwater of some regions of South America and it could have contributed to oral carcinogenesis as in this case.
