Hi just an observation it might be nothing. In my whole life I have known three people with this condition, 2 of which conifrmed this with me. One of the people i knew had this was from work 6 years ago while the other 2 were from college. These where the only people I have ever known with this conidtion. However strange thing is 2 of them were indian and the other one was pakistani..... These to races are pretty much identical gentically. Strange thing is the other day I was in ASDA doing my weekly shopping and got served by a guy who totally looked like he had EC, he was even biting flakes of skin of his lipt ... but get this he was was indian/pakistani in appearance !

Obviously judging from the boards this condition is not exclusive to any race my self included is not indian or pakistani, however it made me think of this condition being genetic... some illness are more prone in certain ethnicities.... for example lupus is more prominant in Afro Carabeans. My sister also has mild EC which again adds to this theory of the condition being genetic.
