I think I remember reading that it could be caused by mycoplasma or other infections... One of my doctors was once considering this as a diagnosis for me, but then he changed his mind after some additional testing (I don't know what test result caused him to change his mind...like everyone else, they all tell me I have autoimmune diseases but the tx for that - immune suppression - just makes me sicker)
Anyway, for sarcoidosis info, see http://emedicine.medscape.com/article/1123970-overview
