[Dystomatosis produced by fasciola hepatica: three cases in Madrid].

: Three cases of hepatic fascioliasis diagnosed in the Department of Internal Medicine are presented. All of the patients live in Madrid, all were fed watercress in the last month and the diagnosis was established during the invasive phase and confirmed by serological testing. We emphasized the importance of the TC scan in the correct diagnosis, the ectopic location of the parasite presentation like subcutaneous thoracic nodule and the efficacy of bithionol in the treatment.
