Eosinophilic fasciitis complicated with peripheral polyneuropathy.

Peripheral polyneuropathy and the complication of eosinophilic fasciitis (EF) is rare; only 2 such cases have been described previously. A 40-year-old woman suffered from swelling of the extremities after strenuous exercise and complained of bilateral paresthesia on the soles of her feet. The diagnosis was EF according to clinical symptoms, peripheral eosinophilia, and histological examination of the fascia. Nerve conduction tests also revealed sensory disturbance as mononeuritis multiplex. After administration of prednisolone, the swelling and tenderness of the extremities improved immediately but the neuropathy lasted for 6 months.
