Patterns of staining for CD8 in T-cell GLL.
(A) Immunoperoxidase stain for CD8 demonstrating distinct membrane staining in confluent aggregates of more than 8 CD8+ lymphocytes. Aminoethyl carbazol chromogen, hematoxylin counterstain; original magnification: × 150. (B) Immunoperoxidase stain CD8 demonstrating a linear array of CD8+ intravascular T cells. Aminoethyl carbazol chromogen, hematoxylin counterstain; original magnification: × 240.
