  4. Porphyria cutanea tarda is the most common subtype of porphyria. The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs. It is a component of hemoglobin, the molecule that carries oxygen in the blood. Hepatoerythropoietic porphyria has been described as a homozygous form of porphyria cutanea

Porphyria cutanea tarda (PCT... Porphyrias are the result of an accumulation of metabolites in the heme biosynthetic pathway; enzyme deficiencies are the cause Porphyria Cutanea Tarda. The most common subtype of porphyria, this disorder results from a deficiency of uroporphyrinogen decarboxylase (UROD), an enzyme critical to the sythesis of heme, an important consituent in hemoglobin, the molecule responsible for carrying oxygen throughout the bloodstream Porphyria cutanea tarda (PCT) skyldes en omsetningsfeil i leveren som kan føre til opphopning i kroppen av en gruppe stoffer som heter porfyriner. I huden reagerer porfyrinene med sollys, og skader i huden. Dette gjør at huden din blir skjør, og lett får sår og vannfylte blemmer.

One type, porphyria cutanea tarda, may also be due to increased iron in the liver, hepatitis C, alcohol, or HIV/AIDS. The underlying mechanism results in a decrease in the amount of heme produced and a build-up of substances involved in making heme. Porphyrias may also be classified by whether the liver or bone marrow is affected Porphyria cutanea tarda (PCT) is the most common human porphyria, due to hepatic deficiency of uroporphyrinogen decarboxylase (UROD), which is acquired in the presence of iron overload and various susceptibility factors, such as alcohol abuse, smoking, hepatitis C virus (HCV) infection, HIV infection, iron overload with HFE gene mutations, use of estrogens, and UROD mutation Porphyria cutanea tarda (PCT; previously called symptomatic porphyria, chemical porphyria, toxic porphyria) is the most common of the porphyrias. PCT was named by Waldenström in 1937 to emphasize the predominant cutaneous manifestations and relatively late onset of disease [ 1 ]

Porphyria cutanea tarda results from underactivity of the enzyme uroporphyrinogen decarboxylase, which leads to accumulation of porphyrins in the liver. Liver disease is common. About 35% of people develop cirrhosis and 7 to 24% develop liver cancer.

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) What is porphyria cutanea tarda? PCT is one of a group of disorders (known as the porphyrias) caused by a range of enzyme defects in one of the biochemical pathways in the body. Any one of these can result in a build-up of chemicals called porphyrins. In PCT the porphyrins are produced from the liver and cause the skin to become very sensitive. Porphyria cutanea tarda may be confused with several other porphyrias that can present with similar vesiculobullous photocutaneous lesions:-Variegate porphyria can be distinguished by finding urinary coproporphyrin > uroporphryin, elevated fecal Protoporphyrin ≥ coproporphyrin, and a distinctive plasma porphyrin fluorescence emission maximum.
