Lichen sclerosus (LS) is a chronic inflammatory mucocutaneous disease that often affects the anogenital area; oral mucosal lesions are extremely rare. A 52-year-old woman presented for evaluation of an 8-year history of a persistent whitish plaque in the buccal mucosa. Intraoral examination revealed multiple elevated whitish plaques diffusely distributed in the buccal mucosa associated with an area of tissue atrophy. Although both leukoplakia and lichen planus were considered, incisional biopsy and later, full excision confirmed the histopathological diagnosis of oral LS. After 6 months of follow-up, there are no clinical signs of relapse. This case highlights the importance of clinical and histopathological findings for the correct diagnosis and treatment of oral LS.
硬化性苔藓（LS）是一种慢性炎症性黏膜皮肤疾病，常累及肛门生殖器区域；口腔黏膜病变极为罕见。一名52岁女性因颊黏膜持续出现白色斑块8年前来评估。口腔检查发现多个隆起的白色斑块弥漫分布于颊黏膜，伴有组织萎缩区域。尽管考虑过白斑和扁平苔藓，但切开活检及随后的完整切除证实了口腔LS的组织病理学诊断。经过6个月的随访，无复发的临床迹象。该病例突出了临床和组织病理学检查结果对口腔LS正确诊断和治疗的重要性。
