Clinical manifestations of photosensitivity in patients with human immunodeficiency virus infection.

A number of light-induced pathologic changes in the skin of individuals with HIV infection have been reported in the dermatologic literature. The relationship between HIV and one of these more well-defined types of photosensitivity, PCT, while still uncertain seems definable and related to an infectious origin. The relationship of retrovirus infection and photosensitivities that are of idiopathic origin in HIV-infected individuals, as well as non-infected individuals, is much more conjectural. The association seems, however, to be more frequent than co-incidental, and the link probably resides in the realm of altered immune modulation. Since individuals with HIV frequently require phototherapy, such light-induced problems are likely to become more common. It is important that the dermatologist recognize these relationships.
