[Successful treatment of recurrent ulcerative stomatitis, associated with cellular immune defect and hypozincaemia, by oral administration of zinc sulfate].

The author observed cellular immune defect confirmed by lymphoblast transformation and hypozincemia in a 15-year old boy whose ulcerative stomatitis had been recurring for 6 years monthly and was treated without success besides local treatment with chronic administration of steroid, isoprinosin, interferon and lysosim. 3 X 50 mg of zinc sulphate given per os daily for 3 months resulted in permanent clinically symptom free condition and in the normalization of the lymphoblast transformation rate.
