ABSTRACT

Lichen planus is a chronic, immunological mucocutaneous disease with a wide range of clinical manifestations. Since oral lichen planus is considered a pre-malignant condition, a recall system has been recommended one to four times annually to facilitate the early diagnosis of malignant transformation. This paper reports the case of a patient with malignant transformation of oral lichen planus and points out the significance of both the recall system and adequate education by dental care providers regarding early detection of transformation into oral cancer.
