Similarly, in the skin of patients with NBCCS, microscopic basal cell lesions were found to be associated with infiltration of hematopoietic cells positive for CD11b/CD16 and CD11c/CD4 that characterize monocytes, macrophages, neutrophils, granulocytes, and natural killer cells as shown in figure 2E. This evidence concerns the gene CD4 and nevoid basal cell carcinoma syndrome.
