Lichen sclerosus et atrophicus manifesting with localized loss of periodontal attachment.
Lichen sclerosus et atrophicus (LSA) is a chronic mucocutaneous inflammatory disorder of uncertain aetiology that is clinically characterized by the appearance of well delimited white plaques or papules, preferentially affecting the skin and genitals, and more rarely the oral cavity. We present the case of a woman with LSA limited to the oral cavity in the form of a well delimited, flat whitish lesion affecting the vestibular gingiva of the right upper incisors and left central incisor, and extending towards the vestibular fundus and frenulum of the upper lip. Widening of the periodontal space was observed, with gingival recession and attachment loss limited to these teeth. Local corticosteroid injections caused the mucosal lesion but not the periodontal alterations to resolve. Emphasis is placed on the importance of knowledge of this condition in relation to establishing a diagnosis, and on its periodontal repercussions.
