Therapy‐resistant erythema of the rima ani

A 76-year-old patient presented to our outpatient clinic with a slowly growing, itchy and painful lesion of the rima ani. It developed about nine months ago, and the treatment with topical corticosteroids, antimycotic and antiseptic creams resulted in only moderate relief of the symptoms. The patient reported about a successful sclerotherapy of hemorrhoids several years ago and also about a partial resection of penis due to a squamous cell carcinoma of the glans in the year 2009. There were no further known skin diseases or allergies. A proctological examination had already been performed but did not reveal any pathological findings, in particular there was no indication of a recurrence of hemorrhoidal disease.
