Idiopathic linear leukoplakia of gingiva: A rare case report

Abstract

White lesions of the oral cavity are not uncommon though majority of them are benign. This case report documents a rare case of idiopathic linear leukoplakia of gingiva with no apparent etiology. Initial examination revealed a non-scrapable linear white lesion on the marginal and papillary gingiva of upper right teeth region. Incisional biopsy was taken for pathologic evaluation. Patient was treated with routine oral hygiene procedures and excision of the lesions. The histopathological results demonstrated hyperparakeratinized/orthokeratinized hyperplastic oral epithelium with orthokeratin-filled clefts and with no dysplasia. Clinical results demonstrated no recurrence after electrosurgical intervention. This paper reports a rare case of idiopathic linear leukoplakia of gingiva which was non-dysplastic in nature. Electrosurgical treatment proved to be successful compared to surgical technique as there was no recurrence even after two years of follow-up.
