Abstract: | BackgroundCowden disease is a multisystemic cancer predisposition disorder, inherited in an autosomal dominant pattern. Cutaneous and visceral lesions are either malignant tumours or are believed to represent hamartomatous growths. Mucocutaneous lesions are present on almost 100% of affected individuals. Nonetheless, some authors consider that the mucocutaneous manifestations of Cowden disease are, in reality, viral warts at distinct steps of evolution. There are only a few studies regarding the oral manifestations of Cowden disease. ObjectivesTo study the oral manifestations of Cowden disease in nine patients clinically and histopathologically. MethodsThe oral mucosal aspects of nine patients with clinical diagnosis of Cowden disease were photographed, and biopsies were taken from typical lesions. ResultsAll biopsied lesions depicted histopathological aspects suggestive of viral warts at distinct steps of development: incipient, well established and in regression. ConclusionOur findings seem to reinforce the poorly understood hypothesis that the mucocutaneous manifestations of Cowden disease are in reality viral warts. Additional studies are needed to explain why a syndrome caused by the mutation of a tumour suppression gene may cause propensity to warts. |
