A case of eosinophilic fasciitis and generalized morphea overlap
Abstract
A 60-year old man developed skin hardening and edema on his extremities. Although he had been treated with oral prednisolone at another hospital, skin stiffness relapsed during tapering of prednisolone. At the initial visit to our department, physical examination showed skin hardening of the extremities and also symmetric erythematous macules on the back. Histological examination revealed fasciitis on the forearm and morphea on the back. Eosinophilic fasciitis is occasionally associated with morphea. However, cases of concurrent eosinophilic fasciitis and generalized morphea are rare. In the present case, CD34 was differentially expressed in both lesions, suggesting eosinophilic fasciitis and morphea are separate diseases with different origin of mesenchymal cells.
