Dirofilaria repens infection case in Hungary: a case report.

A 51-year-old female developed urticarial lesions of her right forearm which progressed into transient edema and subcutaneous swelling. Later a small infiltrated subcutaneous nodule also appeared and was removed in toto. Histopathological examination revealed the presence of Dirofilaria repens. This worm is the cause of an endemic zoonosis in the Mediterranean area. In the past decade many cases have been reported worldwide, but the condition appears rare in Hungary and skin findings have not been described.
