Factitious Dermatitis. Presented byDr. GuyandDr. Jacob.A woman, aged 26, unmarried, presented an eruption that had been present in varying stages of evolution during the two years just preceding presentation. It began following the death of her mother and a subsequent nervous breakdown. The patient said that she was totally blind for three months (she did not see an eye specialist). On both arms, on the abdomen, particularly near the line of the laparotomy wound and the thighs there were either scars of healed lesions or flacid bullae, which she said at times appeared in the course of one hour after a preliminary itching sensation. It was noteworthy that the mucous membranes were free, and that all lesions were within easy reach of the hands. She said that she had not menstruated in three years. She had a marked anesthesia of the pharynx and cornea.DISCUSSIONDr.
