Acute sunburn results from overexposure to the erythemogenic rays of sunlight, which are in the spectral range from 2,900 A. to 3,150 A.1 The following report concerns the short-term treatment of acute sunburn reactions with triamcinolone (Kenacort*). Fourteen patients with severe sunburn were seen during July, 1958. Thirteen were adults, and one a child aged 11 years. Each adult received 16 mg. of triamcinolone, as an initial dose, followed by 12 mg. in divided doses within the next 18 hours (4 mg. every 6 hours for three doses). Nine patients required no further treatment. The remaining four patients, who were the more severely sunburned, required an additional 12 mg. over the succeeding 18 hours. The child was given an initial dose of 12 mg., followed by an additional 12 mg. in divided doses over the next 18 hours for a total of 24 mg. Results Improvement in each
