Porphyria cutanea tarda presenting as a lichenoid eruption

Porphyria cutanea tarda (PCT) is a phototoxic cutaneous disease linked to elevated liver iron levels and photosensitizing heme precursors. Here, we report a 65-year-old man with a history of hypertension and heavy alcohol and tobacco use who presented to clinic for evaluation of an intensely pruritic rash on his arms present for 6 years. A biopsy completed 3 years prior demonstrated a lichenoid drug eruption.
