Penile psoriasis
- about 2% of the population have psoriasis
- anogenital skin (sacrum, buttocks, pubic mound and penis) is a common, and sometimes the only, site of psoriasis
- usually psoriasis is not itchy
- diagnosis is usually clinical
- biopsy is occasionally required for solitary mucosal lesions in uncircumcised patients when Zoon‘s balanitis, Bowen’s disease and extramammary Paget’s disease cannot be excluded
- Treatment
- options for treatment include topical corticosteroids, weak tar preparations and topical vitamin D analogues
- systemic treatment (methotrexate or ciclosporin) may occasionally be indicated for treatment of severe anogenital psoriasis
