5] The RS cells in nodular lymphocyte predominance Hodgkin disease (NLPHD) variant stain positive with antibodies to leukocyte common antigen, L26, and pan-B-cell markers in contrast to the RS cells of other variants, which are Leu-M1 positive and nonreactive with pan-B-cell markers.
T-cell-associated antigens (CD3 and CD45RO) as well as leukocyte common antigen (CD45) were also absent.
Although not all SCCs express epithelial markers, they react strongly with CD56 and leukocyte common antigen expression is negative.
Lymphoepithelioma-like carcinoma tumor cells are immunoreactive to cytokeratin and epithelial membrane antigen and are negative for leukocyte common antigen, confirming their epithelial nature.
The nuclear feature is closer to a lymphocyte, and the cells show lymphoid antigens, such as leukocyte common antigen, CD20, and CD79.
They were negative for epithelial membrane antigen, cytokeratin (high and low molecular weight), CK20, Ber-EP4, breast-2 antibodies, estrogen receptor, progesterone receptor, muscle-specific actin, smooth muscle actin, desmin, HMB-45, S100, neuron-specific enolase, chromogranin, synaptophysin, CD34, leukocyte common antigen, CD3, CD20, CD57, CD68, and factor 13a.
4) In our case, we observed membranous positivity for leukocyte common antigen in the histiocytes that infiltrated the salivary gland, which in our opinion can be regarded as additional evidence that these cells originate from bone marrow-derived monocytes or macrophages.
The assay detects a common antigen produced by toxigenic and non-toxigenic forms of C.
8) This study revealed the tumor cells are macrophages ultrastructurally, and that they express epitopes detected by antibodies to CD68, HAM56, and vimentin, but not with antibodies to cytokeratins, epithelial membrane antigen, S100, HMB-45, leukocyte common antigen, CD34, desmin, or smooth muscle actin.
