Porphyria cutanea tarda (PCT) is a form of porphyria that primarily affects the skin. People affected by this condition generally experience photosensitivity, which causes painful, blistering lesions to develop on sun-exposed areas of the skin (i.e. the hands and face).

Porphyria Cutanea Tarda Clinical Presentation: History

Porphyria cutanea tarda: Literally, the late skin form of porphyria, a genetic photosensitive (light-sensitive) skin disease with onset in adult life with substances called uroporphyrins in the urine due to a deficiency of uroporphyrinogen decarboxylase (), an enzyme required for the synthesis of heme (part of hemoglobin, the pigment in red blood cells that carries oxygen) Understanding Porphyria Cutanea Tarda. Caused by an excess of porphyrins in the blood, porphyria defines a group of diseases. Some of the substances involved in porphyria are described below: Porphyrins are complex molecules that combine with iron to produce heme. Heme is responsible for giving blood its red color There are many different forms of porphyria. The most common type is porphyria cutanea tarda (PCT). Drugs, infection, alcohol, and hormones such as estrogen may trigger attacks of certain types of porphyria. Porphyria is inherited. This means the disorder is passed down through families Porphyria cutanea tarda (PCT) is the most common form of chronic hepatic porphyria (see this term). It is characterized by bullous photodermatitis.
