Porphyria Cutanea Tarda (PCT)

Very rarely, PCT is inherited from one's parents in the manner described for AIP,VP & HC. Most people with PCT did not inherit the disorder and will not pass it on to their children. Here, PCT is secondary to another condition. It may arise in some people because of taking too much alcohol.


Commonly, such people have additionally an excess of iron in their bodies. It may also follow the use of some drugs, such as the estrogen used in the pill or for relief of symptoms of the menopause and after exposure to certain chemicals. People with PCT commonly develop skin problems. They will NEVER suffer an acute attack. Drugs do not hold the same danger for them as they do for people with AIP or VP, although they should avoid alcohol.
