(a) Diffuse infiltration of small- and medium-sized pleomorphic lymphocytes is seen between the fat cells with rimming of the neoplastic cells around one individual fat cell (arrow) (H&E stain; original magnification ×320). (b) CD8 positivity of the neoplastic cells (original magnification ×400). (c) The majority of the cells presents the αβ phenotype (βF1, original magnification ×640). (d) A high proliferative index of the malignant cells is observed (Ki-67, original magnification ×125).
