A common but less often discussed problem is psoriasis of the penis. One area of the body often affected by psoriasis is the end of the penis, known as the glans penis. Flare ups of psoriasis in this area are common due to Koebnerization from sexual intercourse. Use of a condom can help protect the skin of the area from psoriasis-inducing trauma. Psoriasis of the penis is not a venereal disease and can not be sexually transmitted.
Psoriasis of the penis can interfere with sexual enjoyment as a result of the appearance as well as the irritation cause by the condition. Treatment of psoriasis in this area is somewhat complicated by the fact that strong topical steroids cause atrophy or thinning of the skin, a serious side effect which can cause future problems with painful intercourse.
Fortunately, this area of the body is very responsive to treatment with milder steroids such as 1% OTC hydrocortisone and prescription hydrocortisone with iodoquinol creams. Also useful in this area are Protopic and Elidel. Stronger steroids may be used sparingly for very short periods of time under close supervision by your dermatologist.
When the entire genital area is covered with psoriasis, the condition falls into the severe category and under these circumstances, systemic treatment with a pill such as methotrexate or Soriatane or even a biologic drug may be indicated.
