A rare case of periodontal tissue destruction in a patient with lichen sclerosus et atrophicus
Mahajan, Ajay / Dixit, Jaya / Verma, Umesh Pratap
Background: Lichen sclerosus et atrophicus (LSA) is an uncommon disorder of unknown aetiology. The disease is clinically characterised by white, macular lesions on the skin and is usually associated with atrophic condition affecting the vulva and peri-anal skin. Involvement of the oral mucosa with or without concurrent genital or skin lesions has been reported only occasionally. In view of the rarity of reported cases, one lesion affecting only the labial mucocutaneous area is presented. A 17- year-old female patient came to us with the chief complaint of an unaesthetic appearance of her maxillary anterior teeth as well as receding gums. A white mucosal lesion was seen affecting the labial mucosa along with severe bone and gingival tissue loss around her maxillary incisors.
Case report: Clinical examination suggested the diagnosis of LSA, which was confirmed by the histopathological report of the lesion. Intralesional injections of steroids were given twice at an interval of 1 week, accompanied by thorough Phase 1 therapy and instructions for proper maintenance of oral hygiene. The mucosal condition resolved in 4 weeks, the involved teeth were saved and the patient was scheduled for regular recall visits. After 1 year, the patient was satisfied with the treatment outcome.
Conclusion: Although rare in the oral cavity, LSA may affect the periodontal issues. The clinician should be aware of clinical and histopathological findings of this condition.
