Under a layer of a skin, hypoderm and front side of a trapezoid muscle Bioplasm nls software-research of left shoulder girdle has revealed a mass-occupying neoplasm of an oval form, with even distinct contour, of high chromogeneity (6 points at Fleindler’s scale), moderately non-uniform structure, sized 3.7 × 2.0 × 2.3 sq. cm. A little laterally from this neoplasm a similar neoplasm of the smaller size – 1.8 × 1.5 × 17 sq.cm. was found. Survey Bioplasm nls software-research of tissues of a left half of neck and area of brachial plexus one more neoplasm (which it was not palpated at clinical survey) was revealed; it was located in immediate proximity from a vascular plexus (common carotid artery and internal jugular), on a Bioplasm nls software-picture it was similar to previous one (oval shape, with the even contour, high chromogeneity (5-6 points at Fleindler’s scale), sizes 1.3 × 1.0 × 0.9 sq. cm. Bioplasm nls software-angiographic research of neoplasms’ periphery has revealed affection of arterial vessels (4-5 points). Regional lymph nodes were moderately chromogenic (3-4 points at Fleindler’s scale), not enlarged. Brachial plexus trunks were located deeper than neoplasms, they had a usual internal structure and uniform thickness.
