My 50 year old son has had a condition on his arms, back, face for many years. It has been controlled until lately when his dermatologist prescribed Clobetisol. /this durg helped his arms and face, etc. Now he is losing his hair and the whole top is covered with inflammation or something that looks like psriosis. He has never been given a name for what this is, but when it heals, his skin has lost its pigment. Can you tell me what this problem could be? Thank you, Karen Greer, in Texas. My son, Mark, lives in Seattle. Thank you. He is not keeping the name a secret, just can't remember -- says it is a "long name."
