AD defect in keratin causing a benign familial disorder. Lesions are typically white, symptomless, bilateral on buccal mucosa with folded edges. E/O sites include anus, genitals, pharynx, nose and URT

family history and examination is usually sufficient however is there is some confusion with another lesion then biopsy is indicated
