Relationship between porphyria cutanea tarda (PCT) and viral hepatitis.
Recent reports have revealed the high prevalence of serological markers of viral hepatitis in porphyria cutanea tarda (PCT). We present two cases of PCT associated with hepatitis C and discuss the relationship between PCT and viral hepatitis. Case 1: A 50-year-old Japanese male noticed blisters, erosions, and fragility on sun-exposed areas of his skin in November of 1990. He had no history of excessive alcohol intake. He had been taking analgesics for eighteen years. Case 2: A 64-year-old Japanese male was referred in October of 1989 because of pigmentation on sun-exposed areas of his skin. He had been drinking alcohol excessively for 43 years. The hepatitis C virus (HCV) antibody was present in each case. Tests for the HCV antibody and hepatitis B serological markers were run in 5 other patients. HCV antibody was present in 3 of them. The two cases negative for the HCV antibody exhibited the hepatitis B antibody. We speculated that viral hepatitis infection may play an important role in precipitating PCT in cases with a history of a long term excessive intake of alcohol or chemicals.
