ABSTRACT
Papulosquamous cutaneous diseases are a loosely defined category of dermatoses bound together by the fact that they all present clinically with scaly plaques and papules. Seborrheic dermatitis is by far one of the most common cutaneous diseases to manifest itself in the human immunodeficiency virus (HIV) population. Some clinicians also include xerosis, acquired icthyosis, and asteatotic dermatitis, especially in HIV-positive patients. Many of the aforementioned conditions, in addition to being more prevalent, may display a fulminant or unusual clinical presentation in the setting of HIV infection. Psoriasis in HIV-infected patients has the potential to be quite severe, often presenting in an explosive, even erythrodermic manner. HIV-induced or exacerbated chronic plaque psoriasis tends to have all the same characteristics, but its onset has the potential to be more rapid and it can be more severe. Pustular psoriasis is a relatively unusual manifestation of psoriasis that may be seen in HIV infection.
