Expression of CD83 in a tumor-free sentinel lymph node (SLN) and of CD1a in a tumor-containing SLN from a breast cancer patient. Paraffin-embedded (a) tumor-free or (b) tumor-containing SLN tissue was analyzed for expression of CD83 or CD1a, respectively, by immunohistochemistry. Typical examples of dendritic cell morphology stained with each antibody are shown (magnification, × 400).
