Secondary vasculitis to infection by Fasciola hepatica

There is a case of a 38 year-old male patient coming from an area where hepatic fascioliasis is endemic in Peru. He was hospitalized because he showed 4 weeks of symptoms like fever, intense myalgias, erythematous and painful injuries on limb extensions. The electromyography and nerve conduction velocity showed a global inflammatory myopathy. A skin biopsy showed polyarteritis nodosa-type vasculitis. During the evaluation process prior to the immunosuppressive therapy, hepatic Fasciola eggs were found in the parasitological examination of stools. The fascioliasis diagnosis was confirmed by fas2-ELISA: 0.46 (VN <0.20). Clinical symptoms started to subside after treatment with ticlabendazol. Contact with the patient was maintained for a year and there was no evidence of disease recurrence, and he was asymptomatic.
