He developed a right neck mass in August 1984. He had been treated with drugs such as cyanine, streptomycin, and ramexin, and the size of the mass increased gradually. In January 1986, he came to our hospital for surgery. During the operation, the mass was 5.5 × 4 × 3 cm in size, and the surface was smooth. It was located on the deep side of the anterior edge of the right sternocleidomastoid muscle. The posterior edge of the carotid sheath was closely connected with the hypoglossal nerve. The tumor was removed for examination. Microscopic epithelium-like cells and spindle cells can be seen under light microscope. Some regions resemble cancers, some resemble sarcomas, and the tumor tissues are distributed in patches. The cytoplasm of tumor cells is abundant, and there are a large number of brown and black particles inside and outside the cytoplasm.
