Peripheral eosinophil count was higher than normal, ultrasonic exceed examination showed slightly lower back after the left ear acoustic area with surrounding lymph node enlargement, CT indicated the subcutaneous tumor on the lateral side of the left parotid gland, and the enlarged lymph nodes in the bilateral carotid space, submaxillary space, the left parotid gland space and the posterior cervical space. The pathologic examination indicated lymphoid tissue nodular hyperplasia with lymphoid follicular formation, visible thin-walled blood vessels and the increase in the number of eosinophils in accordance with kimura's disease. Immunohistochemistry results showed: CD3(+), CD20(+), CD21 FDC network(+), CD10 germinal center(+), bcl-2(-), bcl-6(-), CD79a(+), Lamda(+), Kappa(+), ki-67 germinal center(+). After 4 weeks of operation, part of the scab skin of the incision was detached, with a small incision in the middle segment, about 0.5 cm long.
