There are very few domestic reports. The two cases reported in our hospital in recent years are reported below. Example 1 (Hospital No. 47994), male, 56 years old, worker, left neck mass, approximately 4 × 4 cm, diagnosed as fibroid and removed in October 1980. Six months after the original incision, there was a mass, and the infiltrativeness quickly expanded to about 15×10cm. No tenderness, no mobility, and no enlargement of the superficial lymph nodes. In March 1982, surgical treatment was performed. During the operation, the block was attached to deep muscles and cervical vertebrae, and the center of the tumor was necrotic and liquefied. The basement was wide, and the adhesion between the tumor and the vertebral body was difficult to separate. Only partial resection of the tumor was performed. The tumor was resected with a size of 5×3×2 cm and the cut surface was gray and black. pathology
