Key Takeaways
Porphyria cutanea tarda is a rare metabolic disorder that is caused by an abnormality in the enzyme uroporphyrinogen decarboxylase. Symptoms of this disorder usually involve the skin, as it can lead to blisters and skin discoloration. Treatment for this disorder usually involves medications such as hydroxychloroquine and phlebotomy, as well as lifestyle changes such as avoiding alcohol.
