Oral squamous cell carcinoma in a case of dyskeratosis congenita.

Abstract

Oral manifestations of dyskeratosis congenita (DCG) have received little attention in dental literature. This report is a case of dyskeratosis congenita in a 17-year-old female which was associated with oral lesions such as leukoplakia, superimposed candidal infection, desquamative gingivitis, and severe periodontitis. Histopathologic examination of the granular lesion on the right lateral border of the dorsum of the tongue showed well-differentiated squamous cell carcinoma. Etiopathogenesis, clinical features, and laboratory findings of this disease are discussed.
