The lymphoma at autopsy was analysed using a streptavidin-biotin procedure with monoclonal antibodies against the following cellular differentiation (CD) antigens: CD20, CD79e, CD2, CD3, CD4, CD5, CD7, CD8, CD30, CD15, and also the ALCL markers ALK-1 and Ki-67, showing immune profile consistent with CD30-positive ALK-1 negative ALCL Immunohistochemistry showed an immune profile consistent with CD30-positive ALK-1 negative ALCL (Table 3 and Fig. 2). Here, CD5 is linked to anaplastic large cell lymphoma.
