| Abstract: | The mononuclear cells of the infiltrate in lichen planus lesions of skin and oral mucosa have been identified by detection of their membrane receptors in frozen-tissue sections. By this method, the infiltrate would appear to consist of predominantly T lymphocytes, some macrophages and only a few B cells. The pathogenesis of lichen planus is discussed in the light of these findings. |
