Definition
Porphyria is a group of inherited disorders involving abnormalities in the production of heme pigments (the base material responsible for hemoglobin (red blood cell pigment), myoglobin (reddish muscle cell pigment) and another group of materials called cytochromes.
Porphyrias are characterized by three major findings: photodermatitis (light sensitivity causing rashes), neuropsychiatric complaints, and visceral complaints (such as abdominal pain or cramping).
