Human Immunodeficiency Virus Associated Sporadic Nonfamilial Porphyria Cutanea Tarda.

Porphyria cutanea tarda (PCT), a relatively uncommon metabolic disease, is the most common cutaneous porphyria. Here, we present the case of a patient diagnosed with sporadic, nonfamilial PCT that presented with classical cutaneous findings and multiple risk factors, including alcohol abuse, human immunodeficiency virus/AIDS, that have been strongly associated with the sporadic form of PCT.
