Psoriasis in a Syphilitic Person. Presented by Dr. George M. Lewis.
J. B., a man aged 43, first had an eruption on the left palm five years ago. The left sole became affected soon afterward, and the condition has not improved since then. For two years the right palm was also involved. There was no troublesome pruritus; some tenderness of the affected skin was present. Therapy from four physicians included various local medications, ultraviolet radiation and three hundred and sixty injections (presumably of trichophytin). The patient had continuous treatment for one and a half years for syphilis about ten years ago; three years ago a short series of injections of arsphenamine was administered.No nails are involved. The interdigital tissues are unaffected. The left sole and to a lesser degree the right palm show a subacute erythematous keratotic and scaly eruption. There are no vesicles.There was no obvious focus
