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.
扁平苔藓（LP）是最常见的伴有口腔表现的皮肤病。口腔病变包括广泛的临床表现。我们报告一例56岁女性，其颊黏膜和下唇黏膜出现糜烂性扁平苔藓。除了典型的糜烂外，在下唇黏膜的红斑背景上还观察到小的白色角化丘疹。下唇病变的活检显示出一种不寻常的组织病理学表现，即针对唾液腺导管的苔藓样炎症。这可能是毛发扁平苔藓和毛孔扁平苔藓的唾液腺类似物。
