Abstract
Porphyria cutanea tarda (PCT) is caused by inherited or acquired partial deficiency of the uroporphyrinogen-decarboxylase (Uro-D) enzyme activity. It is the most common form of porphyria. The main triggering factors to the development of porphyria cutanea tarda are alcohol, hepatitis C virus and human immunodeficiency virus. There are several reports of PCT associated with drugs, among them, antiretroviral therapy. We describe three HIV-positive patients, which showed photosensitivity as well as the emergence of tense blisters on sun-exposed areas during the use of highly active antiretroviral therapy (HAART) and discuss the possibility of PCT after the use of these drugs by those patients.
