Intermission - Porphyria, The Great Mimicker

Intermission: Porphyria, the great mimicker of other diseases, and other diseases and disorders that mimic porphyria.

Disclaimer: By no means is this a complete list!

     Many diseases and disorders can mimic the 8 types of Porphyria. When you get diagnosed as one of these, and you know you are unlikely to have one of them, remember to ask yourself, what if it is porphyria? What if it's not porphyria? Testing is better safe than sorry if you know in your heart it might not be what you're diagnosed with. Always get second and third opinions.
