Cases of BI-ALCL with LNI with low tumor burden. A and B, Case 2. A, Lymph node with ~5% tumor burden involving the subcapsular sinus (hematoxylin and eosin). B, CD30 immunohistochemistry highlights lymphoma cells in the subcapsular sinus (anti-CD30 with hematoxylin counterstain). C and D, Case 9. C, 1% tumor burden in a sinusoidal pattern;only rare large cells are identified (hematoxylin and eosin). D, CD30 immunohistochemistry highlights scattered lymphoma cells with a sinusoidal pattern (anti-CD30 with hematoxylin counterstain).
