Nicotine replacement lozenges: Abuse-related hyperkeratosis of the lateral border of the tongue. A case report

Abstract

A case of a white patch on the right lateral border of the tongue, found to be hyperkeratosis induced by long-term habitual placement of nicotine replacement lozenges (NiQuitin CQ) in the right lingual sulcus, is presented. The lesion became less evident once the patient varied the intraoral location and reduced his consumption of these tablets.
