Well known diagnostic markers for CTCL include CD2, CD3, CD4, CD5, CD7, CD8, CD14, CD16/56, CD19, CD25, CD45, CD45RA, and CD45R0 [2]; although dissonant with cutaneous B-cell lymphomas and plasma cell disorders, no dependable protein marker for CTCL has been discovered. The gene discussed is CD4; the disease is primary cutaneous T-cell non-Hodgkin lymphoma.
