| Abstract: | BackgroundUnlike other types of lichen planus (LP), there are no series concerning male genital LP.ObjectiveTo describe the clinical characteristics, diagnosis, and response to treatment of male genital LP.Patients and methodsA retrospective study of male patients with genital LP consulting a dermatologist specialized in anogenital diseases between January 2010 and 2019. Demographic data, history, functional signs, clinical characteristics, pathology, complications, and treatment efficacy were collected.ResultsEighty-nine patients were included at four centers. The median age was 51 years. Most patients were uncircumcised and asymptomatic. In 88.8% of cases, only the genital mucosa was involved. Erythema (71%), papules (21.3%), lacy network (15.7%), atrophic lesions (15.7%), erosions (14.6%), and post-inflammatory hyperpigmentation (2.2%) were less frequently observed. Biopsy results confirmed LP in 61.3% of cases but could not rule out other inflammatory genital dermatoses in other cases. Anatomic complications were observed in 30.3% of patients. Topical corticosteroids (TCS) induced remission in most cases. Tacrolimus efficacy was comparable to that of TCS.ConclusionMale genital LP is a rare inflammatory disorder chiefly affecting uncircumcised men. It is found predominantly on the mucosal component of the penis and presents as non-erosive inflammatory balanitis in most cases, with frequent partial or complete remission on treatment with TCS. |
