Porphyria cutanea tarda is the most common subtype of porphyria. [1] 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.
Porphyria Cutanea Tarda (PCT): PCT is the most common form of porphyria, with an estimated prevalence of 1 to 2 cases per 10,000 individuals in the general population. It predominantly affects adults, with a higher prevalence in men than in women.
Mutations and deficiency in this enzyme are known to cause familial porphyria cutanea tarda and hepatoerythropoietic porphyria. [5] At least 65 disease-causing mutations in this gene have been discovered.
Nearly all cases of porphyria cutanea tarda [18] exhibit blister formation on the skin within 2–4 days of light exposure. Variegate porphyria [19] and hereditary coproporphyria [20] can also exhibit symptoms of light-induced blisters. [18]
Dominantly inherited cutaneous and neurocutaneous porphyrias (porphyria cutanea tarda, hereditary coproporphyria, variegate porphyria and erythropoietic protoporphyria) have been associated with solar urticaria. The occurrence of drug-induced solar urticaria may be associated with porphyrias. This may be caused by IgG binding, not IgE.
The multiple causes include the side effects of drugs, associations with cancer, and possible links with eating disorders. ... Porphyria cutanea tarda may manifest in ...

Acute intermittent porphyria (AIP) is a rare metabolic disorder affecting the production of heme resulting from a deficiency of the enzyme porphobilinogen deaminase. It is the most common of the acute porphyrias .
