case_images: Biopsy of soft tissue from the left thigh revealed: (a) at 10x magnification shows lymphoid infiltrate with pattern resembling lobular and septal panniculitis, and (b) at 40x magnification shows lymphoid infiltrate with abundant cytoplasm. At 100x magnification with oil-immersion biopsy showed (c) atypical lymphoid cells with atypical and irregular nuclei as well as numerous fat cells, (d) numerous single-cell necroses and atypical lymphoid infiltrate, (e) mitotic figure in the center with areas of necrosis and fibrosis, (f) mitotic figure with scattered histiocytes and area of necrosis, and (g) area of necrotic debris.

case_images: On low-power field, results for the left groin area sample showed extranodal fibroadipose tissue containing a lymphoid infiltrate with a pattern similar to lobular and septal panniculitis (at 10x magnification) (Figure 2(a)). On high-power field (Figures 2(b)-2(g)), the lymphoid cells were markedly atypical with irregular nuclei. CD8 but negative for CD4 and CD56 (Figure 2). CD4 was positive in scattered small lymphocytes and frequent interspersed histiocytes. CD20 was positive in rare, scattered B-cells.
