Figure 1: (a) Huge swellings at the right neck and right axillary region having a smooth surface and dilated veins. (b) Swelling at the right neck extending to the right shoulder and scapular region. (c) Cytology smear showing a monotonous, discrete, population of small-to-medium round cells having scanty cytoplasm, high nuclear-cytoplasmic ratio, and fine granular chromatin (MGG stain, ×400). (d) Core biopsy of right axillary swelling showing a monotonous population of uniform appearing small lymphoid cells having coarse chromatin, inconspicuous nucleoli, and minimal mitotic activity (H and E stain, ×400). (e) Immunohistochemistry showing strong immunopositivity in tumor cells for CD45 (leukocyte common antigen) (×400). (f) Immunohistochemistry showing immunopositivity in tumor cells for CD23 (×400). (g) Immunohistochemistry showing immunopositivity in tumor cells for CD20 (×400). (h) Immunohistochemistry showing tumor cells immunonegative for CD5 (×400). (i) Bone marrow biopsy showing a small focal deposit for small lymphocytic lymphoma (H and E stain, ×400). (j) Immunohistochemistry of bone marrow biopsy showing CD20 immunopositivity of CD20 in focal small lymphocytic lymphoma deposit (×400)
