- Abstract:
- AIMS: To analyse 90 vulvar and 72 penile cases of lichen sclerosus (LS) on haematoxylin and eosin sections for vascular changes and the vascular infiltrates immunohistochemically with antibodies to T cells, B cells and antigen-presenting dendritic cells. LS is a skin disease of presumed autoimmune origin. Autoimmune diseases are mediated by lymphocytes which occasionally produce a lymphocytic vasculitis. METHODS AND RESULTS: Three types of lymphocytic infiltrates were identified: (i) perivascular lymphocytic infiltrates without damage to vessel walls; (ii) lymphocytic vasculitis in three forms: (a) concentric lymphohistiocytic infiltrates with lamination of the adventitia by basement membrane material which was typical for penile LS; (b) lymphocytic vasculitis with dense perivascular lymphocytic cuffing with occasional fibrin deposition in vessel walls and subendothelial lymphocyte infiltration, quite common in vulvar LS; and (c) intramural lymphocytic infiltrates in large muscular vessels; (iii) leukocytoclastic vasculitis in LS was exceptionally rare. In lymphocytic vasculitis, CD20+ B cells, CD4+ T cells and dendritic cells were the principal infiltrating cells. CONCLUSIONS: Dendritic cells capture (foreign) antigens after entry into the affected tissues and initiate immune responses acting as a matrix on which antigen-specific T and B cells interact. The described vascular features are indicative of antigen-mediated vasculitic changes in LS.
