Hepatoerythropoietic porphyria (HEP) is an inherited cutaneous porphyria caused by a deficiency of the enzyme uroporphyrinogen decarboxylase.[1][2] It is the autosomal recessive form of familial Porphyria Cutanea Tarda (f-PCT).[1] The manifestations of HEP resemble Congenital Erythropoietic Porphyria (CEP), with symptoms of skin blistering that usually begin in infancy.[1][2] Treatment may include scheduled phlebotomy and low dose hydroxychloroquine.[1]
