SUMMARY.— A significant increase of the mean IgA globulin value was noted in 105 patients with ordinary psoriasis whereas the mean IgG and IgM globulin levels remained normal. Thirty‐two of these patients received u.v. light therapy which resulted in resolution of the skin lesions. At this stage the IgA levels fell to the normal range. The possibility of the skin eruption influencing the IgA serum levels is discussed.
