VITAMIN D therapy has been used in cutaneous tuberculosis by a large number of clinicians in many countries since the first reports of Charpy and Dowling extolled the value of calciferol (vitamin D2) in the treatment of lupus vulgaris. That the method has real value is proved beyond a doubt, but there are still some unanswered questions about the action and use of this potent vitamin; therefore, a review of our experience and of that of others up to the present time seems in order.
In using calciferol in the treatment of cutaneous tuberculosis at the University of Minnesota Hospitals, the French and English methods of administration have been combined. We prefer Dowling and Thomas' adjustment of daily doses to each patient. Our rule has been to give, orally, 1,000 units per kilogram of body weight per day to the bedridden patient and up to 2,000 units per kilogram
