Psoriasis associated with human immunodeficiency virus/acquired immunodeficiency syndrome.

Since the prevalence of psoriasis is between 1.5 to 2 percent, it would be expected to occur by chance in a person infected with HIV who is genetically predisposed to psoriasis. Several studies in the literature on HIV/AIDS-associated psoriasis have reported such percentages of frequency. Although psoriasis is a low priority for a patient with HIV/AIDS who is coping with many other cutaneous conditions and cancers, when treating the HIV/AIDS-infected psoriatic patient, immunosuppressive drugs are contraindicated because of their serious impact on an already immunodeficient person.
