Summary

285 various pigmented skin lesions from 282 patients were treated over the past 2 years and 10 months using the square and uniform intensity laser equipment. Also, laser effects on 44 skin specimens were studied histologically. The treated clinical lesions included 111 pigmented nevi, 97 nevi spili, 6 Becker's nevi, 10 epidermal nevi, 22 senile freckles, 16 seborrheic keratoses, and 23 other skin lesions. Satisfactory results 6 months or more after the final treatment of 212 of the skin lesions were obtained in 12/96 (12.5%) pigmented nevi; 13/75 (17.3%) nevi spili; 3/5 (60.0%) Becker's nevi; 3/7 (42.9%) epidermal nevi; 9/17 (52.9%) senile freckles; and 9/12 (75.0%) seborrheic keratoses. Judged on the histological examination of pigmented nevi, satisfactory results were obtained in 5 out of 11 superficial compound nevi, 1 out of 32 deep compound nevi, and 2 out of 12 deep intradermal nevi. Assessment methods will be discussed, and ruby laser treatment will be compared to conventional therapy.
