Radiotherapy of Benign Dermatoses: Indications, Practice, and Results

“…In many instances grenz rays may be used effectively; infiltrated lesions respond better to soft X rays. Grenz rays are given in three to four separate doses of 200 to 300 R; soft X rays (D1/2 3 to 4 mm, HVL 0.2 to 0.3 mm A1), in three to four fractions of 75 to 150 R at weekly intervals ,,,. In eczematous conditions and in psoriasis the number of courses should not exceed two to three with intervals of at least three months between them.…”

“…The main indications for radiation therapy in psoriasis are severe involvement of the palms and soles and especially of psoriatic nails ,,. Psoriasis in those sites is often unyielding to other forms of treatment.…”

“…T he number of patients treated with ionizing radiation, both for skin cancers and benign dermatoses, has decreased markedly during the past decades ,,,,. In the matter of treating cutaneous cancers, this drastic change is due mainly to advances in conventional dermatosurgical techniques, and the introduction of new therapeutic methods, namely, cryosurgery, chemosurgery and fresh‐tissue microscopically‐controlled surgery, and cytostatic or immunosuppressive therapy.…”

“…We select radiation of superficial quality with half‐value depth (D1/2) that corresponds to estimated or measured depths of skin diseases to be treated, and we limit our dosage to the least effective total amount suitable for each ,,,,,. Obviously, the sites of areas to be treated are of great importance, particularly close to the gonads, and in other places overlying radiosensitive organs.…”

“…The use of cones and lead shields outlining areas to be treated is also very important in order to reduce scatter‐radiation to a minimum . As emphasized in the article by Rowell, the maximum dose per lifetime administered for benign dermatoses should be limited to 800 to 1200 R, and should be given in small fractions at long intervals ,,. Simultaneous treatment with irritating topical agents (especially tar preparations) should be avoided.…”
