Case 1: A female patient, 50-year-old performed abdominal computed tomography scan that detected a tumor lesion of 8.0 cm in the mesentery. She underwent resection of the lesion. Microscopic examination revealed epithelioid neoplasm, interspersed with lymphocytes, and positive immunohistochemical staining for CD21 and CD35. The patient underwent adjuvant chemotherapy. Case 2: A male patient, 21-year-old presented right-sided neck mass measuring 7.0 cm. The biopsy revealed proliferation of spindle cells, interspersed with inflammatory infiltrate and storiform arrangement, and positive immunohistochemical staining for CD21 and CD23.
