Excision of a metastasis of malignant melanoma with a continuous beam argon laser has been accomplished by University of Cincinnati surgeons.

The January operation is believed the first successful clinical use of the bloodless procedure.

Although insufficient time has passed to determine the success of the excision, it appears the entire 2 × 4.5 cm lesion was removed from the patient's right thigh, according to Leon Goldman, MD, head of the Department of Dermatology and director of the laser laboratory.

The 45-year-old man, who also had multiple metastases of the melanoma on other parts of his skin, was referred to the Cincinnati group by the National Cancer Institute.

The 15-minute operation was accomplished with an instrument that cast a continuous light beam of 2 watts power output. The focused beam of light was directed around the tumor with the aid of a curved mirror.
