Fig. 1 Liver biopsy specimen showing angiotropic large cell lymphoma. A, Polymorphous lymphocytic infiltrate and endotheliitis in portal and sinusoidal regions. B, Some lymphocytes contain enlarged, atypical nuclei (arrows). (A and B, Hematoxylin-eosin; original magnification, x433.)

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.)

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.)
