First time eosinophilic fasciitis (EF) was described by Shulman. It occurrences predominantly in young men, rarely older women, sporadic in children. The illness was characterised by swelling of the extremities, skin changes, myalgia, and elevation of the peripheral blood eosinophil count and hypergammaglobulinemia. It is followed by rapidly progressive cutaneous and subcutaneous induration. The histopathologic examination in the region of affected skin shows thickening of the fascia, deep dermal fibrosis and infiltration mainly consists of lymphocytes, plasmocytes, eosinphils. It is suggested that the cells from infiltration induce fibrosis. The tryptophan disturbance has significant influence on development of EF in predisposed persons. Eosinophilic fasciitis is classified to wide spectrum of scleroderma disorders by many authors. The authors tried to show differences between EF, morphea and systemic scleroderma.
