Porphyria cutanea tarda in beta-thalassemia trait carriers.

ABSTRACT

The authors report 5 cases of porphyria cutanea tarda (PCT) occurring in carriers of the beta-thalassemia trait. This hematologic condition may be responsible for the development of liver damage resulting in siderosis, higher susceptibility to hepatitis B virus infection, and the earlier appearance of clinical features of PCT. Consequently, the authors propose chelation therapy with long-term subcutaneous desferioxamine infusions.
