Oral lichen planus (OLP) is one of the most common oral mucosa diseases; however, familial OLP is uncommon. The present study reported and analyzed patients with familial OLP (n=18) in eight different Chinese families between January 1, 2012 and December 31, 2013. Parameters analyzed include gender, age at diagnosis, lesion distribution and lesion type. The follow-up period for each patient was a minimum of 1 year. In this survey, 18/88 individuals in the eight families were affected. Females were more frequently affected, and the female to male ratio for familial OLP (2.2:1) was higher compared with that previously reported for nonfamilial OLP (1.4:1). The age at diagnosis, lesion distribution and lesion type showed consistency with reports concerning nonfamilial OLP, with the exception of family VI, in which 4/5 children had OLP/LP lesions and were of an early age at diagnosis. There were two families in which three generations had been affected by OLP. In addition, it appeared that patients of the same generation in the same family were of a similar age at diagnosis. No malignant or premalignant lesion was identified in the 18 individuals diagnosed with OLP from the eight families. The present study supports the hypothesis that genetic predisposition may serve a role in the etiology of OLP.
