Oral Lichen Sclerosus et Atrophicus - Literature Review and Two Clinical Cases

Lichen sclerosus et atrophicus (LSA), also called Lichen sclerosus (LS) is a chronic, benign, depigmenting disease of the skin and mucous membranes, most frequently affecting genital mucosa and skin. Involvement of the oral mucosa without concurrent genital or skin lesions has very rarely been reported in the literature. Here we report on two Chinese women with LSA limited to the dorsum of the tongue, and describe the clinical manifestations and histopathological findings of these two patients.
