Figure 3: Immunohistochemical staining of the paraffi n section of the case described in Figure 2C and D. The lesional lymphoid cells were mostly CD3+, CD20– , CD4– , and CD8+ and histiocytes CD68+ and MPO+. (a) Most of the cells including those around capillaries are CD3+ (×400). (b) The blastoid cells especially around capillaries are positive for CD8 (×400). (c) The Kikuchi histiocytes are positive for CD68 (×400). (d) The Kikuchi histiocytes are also positive for MPO (×400)
