Eosinophilic fasciitis: A case report with a brief literature review

Abstract

Eosinophilic fasciitis (EF) is a scleroderma-like immune-allergic disorder of unknown etiology and pathogenesis. This rare disease is characterized by the progressive induration of the skin and soft tissue, and peripheral eosinophilia. Here, we report a case of EF. A 21-year-old female was referred due to edema in the upper and lower extremities for 1 month. Laboratory results were unremarkable except for severe eosinophilia. Parasite infestation, venous thrombosis, and cardiac and renal problems were excluded. Magnetic resonance imaging of both the lower extremities revealed symmetrical thickening and contrast enhancement of crural fascia with adjacent subcutaneous fat infiltration. A full-thickness biopsy at the lower extremity showed infiltration of the fascia by eosinophils, plasma cells, and lymphocytes with marked edema. Thus, this patient was confirmed to have EF and she was treated with systemic corticosteroids, resulting in a remarkable improvement in both edema and eosinophilia.
