CD21

a type I transmembrane protein found on B cells, follicular dendritic cells, pharyngeal and cervical epithelial cells, some thymocytes, and some T cells that plays a role in signal transduction; expressed in hairy cell leukemia, B-cell lymphoma, and some T-cell acute lymphocytic leukemias.

Immunohistochemical analysis showed that neoplastic cells in areas of follicular dendritic cells were diffuse positive for CD21 and vimentin, focal positive for S-100, CD23 and p53 (10%), negative for LCA, CD20, CD30, CD45RA, CD68, pancytokeratin, HHV-8 and EBV.
