Porphyria cutanea tarda
Porphyria cutanea tarda (PCT) is characterized by a skin blistering eruption that develops in sun exposed areas of the skin. It is the most common cutaneous porphyria world-wide, and classically associated with hepatic injury but also estrogen use, cigarette smoking, and HIV. In any case of photodistributed persistent blistering skin condition, PCT must be high on the differential. This case of a carpenter diagnosed with PCT not only illustrates a classic case but also the opportunity to achieve significant response to therapy in a motivated patient particularly with improved access to direct-acting antivirals (DAA) for hepatitis C treatment.
