Maiman[1] produced the first optical laser in1960 using a ruby crystal emitting intense monochromatic red light energy capable of causing small burns off varying intensities. Shortly after this discovery by Maiman, uses of laser in dermatology were explored. Various laser sources in dermatology are ruby, argon, carbon dioxide, neodymium-YAG, tunable dye laser and ultraviolet laser[2],[5] .

Lasers in dermatology have been used in conditions such as pigmented nevi, tattoos, angiomas, spider nevi, benign pigmented le­sions, angiofibromas, telangiectasia, protwine stains, lymphangioma, epithelioma, syringoma, keloids, warts etc.

The laser source used in this work is medilas-2 MMB-AT Neodymium YAG laser with He-Ne laser for pilot light. Full aseptic precautions were taken during operation. The laser machine was used in every case after full adjustments, due precautions and checks.

The dermatological conditions treated were (no of patients) : acrocordon (5), be­nign pigmentation (1), granuloma pyogenicum (1), Wart (2), angioma (1), nevus verrucosus (1) and basal cell epithelioma(1)

All treated lesions benefited from the procedure. While acrocordon, granuloma pyogenicum, wart and angioma were perma­nently and completely removed, the pig­mented nevus and benign pigmentation did not show satisfactory end cosmetic result. Hyperpigmentation persisted in one cse of acrocordon after its destruction. Basal cell epithelioma was destroyed fully and has not shown any recurrence during eight months follow up period. In one case of acrocordon, the patient continued to experience mild burning sensation at the site of destruction for nearly three months.

Nd : YAG laser has been used infrequently for treating angiomas, melanoma, keloids and warts. While complications of ar­gon and CO 2 laser are well documented[4],[5],[6], those of ND : YAG laser are not, may be because it has not been used frequently in dermatology. Some of the predictable complications are; hypertrophic scar, unex­pected pigmentary changes, pain, prolonged healing, infection and atrophic scarring. Though application of laser has shown promising results, we must await proper evaluation of laser research, understanding of laser-tissue interaction, patient acceptability and economic viability.
