3. Fig. 2
Immunohistochemical appearance of hepatic angiotropic large cell lymphoma. Atypical lymphocytes (closed arrows) are positive for B-cell markers CD20 (A) and 4KB5 (B) and negative for T-ceilmarkerCD3 (C). Associated reactive T-cell lymphocytes (open arrows) stainpositively with CD3 antibodies (C). (A, B, and C, x250.)

5. Fig. 4
Lymph node biopsy specimens showing follicular small cleaved cell lymphoma, possible precursor to angiotropic large cell lymphoma. A, Neoplastic intrafollicular lymphocytes are immunoreactive for bel-L. (Anti-bcl-2; original magnification, x42.5.) B, Numerous small cleaved cells are present in a follicular center and adjacent mantle region. (Hematoxylin-eosin; original magnification, x240.)
