Figure 1.
BAFF immunoreactivity in breast carcinoma (A), DCIS (B, arrowhead) and normal appearing duct (C, arrow) and lobule (C, arrowhead). Normal adipocytes are stained positively for BAFF (Pannel A, arrowhead). In D, a higher magnification is shown, in which a homogeneous cytoplasmic BAFF immunoreactivity is shown, with more prominent cell membrane staining. E: Normal Ig isotype staining.
