Beyond Sunburn: Recognizing and Managing Erythropoietic Protoporphyria in Practice

EPP arises from reduced ferrochelatase activity and excess protoporphyrin made largely in the bone marrow. Accurate diagnosis depends on choosing the right specimen and the right laboratory, a step commercial assays often get wrong.

Years can pass between the first symptoms and a correct EPP diagnosis, and those years carry risk. The discussion links delayed recognition to protoporphyric hepatopathy, iron deficiency, and vitamin D deficiency.

Strict photoprotection remains the foundation of EPP care, and only one therapy is approved worldwide. Earlier diagnosis and oral agents that lower protoporphyrin production emerge as the field's most pressing needs.
