Erythropoietic protoporphyria (EPP) is an inherited disorder of the haem metabolic pathway. It causes disabling cutaneous photosensitivity and, sometimes liver disease due to the accumulation of protoporphyrin in blood, liver and other tissues.(1) Holme SA et al reported the median age at onset and diagnosis in patients with EPP in the UK as 1 and 12 years respectively, with diagnosis being delayed until the age of 20 years or more in 34% of their patients.(2) However, late presentation of EPP in adults has been reported.(3) This article is protected by copyright.
