Rheumatism, skin and subcutaneous connective tissue

Active phase of arthritis characterized by an almost constant involvement in the rheumatic process of skin vessels. However, identify histomorphologically vasculitis, capillarity, cell-mediated reactions with participation of histiocytes, lymphocytes, fat cells often clinically asymptomatic. To pathognomonic rheumatic lesions, denoted by A. A. Kissel as "absolute signs of rheumatic fever", include erythema annulare and rheumatic nodules. Much less characteristic and therefore have no significant diagnostic value polymorphic exudative erythema (erythema exudativum multiforme), erythema nodosum (erythema nodosum) and the resulting highly active forms of the disease punctulata hemorrhagic rash - peliosis rheumatica.
