[Morphologic changes in skin tumors induced by pulsed laser radiation].
Pathomorphological changes in melanoma, basalioma, and squamous cell carcinoma of the human skin caused by impulse neodime laser radiation were studied. Laser radiation was found to exert damaging effects on the tumour of various degrees of intensity, the degenerative changes reaching the highest degree, necrosis, in the zone of the direct effect of the ray. Morphological changes in tissues developing under the influence of laser radiation are in many aspects similar to electrocoagulation necrosis. At the same time, foci of laser lesions have some features distinguishing them from common thermal injuries. Cytological examination was shown to be a highly effective method permitting to determine the degree of radical healing of skin tumors treated with the laser ray.
