A 59-year-old man is admitted with a painful, blistering rash on the dorsal aspects of both hands. He has a medical history of alcoholism and admits to a recent relapse and has been drinking heavily over the past week. He is admitted and stabilized. A diagnosis of porphyria cutanea tarda (PCT) is made based on increased circulating porphyrins in the blood and decreased URO-decarboxylase . He is discharged to a rehabilitation facility and follows up in your clinic 2 weeks later. He has been abstinent from alcohol but his rash has persisted, and now he also has some blistering on the legs and feet. Which of the following treatment modalities is most appropriate?
