Immunohistochemical analysis of the expression of selected cell lineage markers (CD4, CD8, CD68, c-Kit, Foxp3, CD56, CD20) in cutaneous variant of lichen planus.
Lichen planus (LP) is considered to be an immune-mediated disease of a not fully understood etiology. There are scarce data on the immune cells forming the band-like infiltration in cutaneous LP (CLP). The objective of the current study was to investigate the immunohistochemical pattern of cells forming the infiltrate in CLP by assessing the immunoexpression of selected cell lineage markers.The immunohistochemical analysis of the expression of CD4, CD8, CD20, CD56, CD68, c-Kit, and Foxp3 was performed in formalin-fixed paraffin-embedded (FFPE) biopsy specimens from 14 cases of CLP and 11 healthy volunteers.The expression of CD4 (P
