I don't think this is unusual at all. I've heard of this happening to many people. Chemo drugs interfere with the how cells act, how they divide/replicate themselves and I don't think they are always particularly specific to one type of cell, so even though a certain chemo drug is selected for it's activity against a certain cancer, it may have also target skin cells as well. (My mother takes the above mentioned drug Methotrexate for her psoriasis). If he hasn't had chemo, maybe it's just the removal of an offending illness causing stress to your father's body that is now improved?? Hope your father enjoys his clear skin, and his recovery is swift and complete.......
