Lichen planus sialadenitis: a mucosal analog of lichen planopilaris and lichen planoporitis

Silvia Vanessa Lourenço et al. J Cutan Pathol. 2010 Mar.

Abstract

Lichen planus (LP) is the most prevalent dermatological disorder with oral manifestation. Oral lesions comprise a broad spectrum of clinical presentations. We report the case of a 56-year-old woman who presented erosive LP on the buccal and lower lip mucosae. Besides typical erosions, small white keratotic papules on an erythematosus background on the lower lip mucosa were observed. Biopsy of lower lip lesions showed an unusual histopathological presentation consisting of a lichenoid inflammation targeted to salivary gland ducts. This is probably a salivary gland analog of lichen planopilaris and lichen planoporitis.
