Recently, the occurrence of pityriasis rubra pilaris (PRP) has been reported in patients with HIV infection. It presents different clinical features, and has a poorer prognosis, than the classical adult type of PRP. We report the occurrence of severe PRP in an HIV-infected patient, and review the previously reported cases of this association. We propose the designation of a new category of PRP (type 6), characterized by the presence of HIV infection, usually without immunosuppression, a poor prognosis and response to treatment, and the development of nodulocystic and lichen spinulosus lesions.

We found the CO2 laser to be a better therapeutic tool than the argon laser to treat AF, especially in those patients with multiple and protuberant AF. The argon laser would be more useful in those patients with very red AF and light complexion, and the pulsed dye laser in those with very red and flat AF.

Most of the side-effects and complications produced by the FPDL are usually transitory, and it is essentially a very secure technique.
