Erroneous diagnosis of genital lichen planus

Abstract

Clinical case of 62 year old patient complaining of rash on the glans of the penis is reported. It was known from the case history that genital rashes first appeared in spring 2020 in the form of two “red dots” associated with no subjective sensations. During the initial visit to dermatology clinic (in London) in June 2020 no diagnosis was established; antibiotics and application of topical emollient were prescribed. The patient did not take treatment as prescribed. During the repeat visit to dermatologist (in Moscow) lichen planus was diagnosed; application of alclometasone dipropionate cream on the rashes 2 times a day was prescribed. Rashes resolved completely in 10 days with treatment.
