title: Extra-hepatic fascioliasis with peritoneal malignancy tumor feature.
abstract: Fascioliasis is a zoonose parasitic disease caused by Fasciola hepatica and Fasciola gigantica and is widespread in most regions of the world. Ectopic fascioliasis usually caused by juvenile Fasciola spp., but in recent years a few cases of tissue-embedded ova have been reported from different endemic areas. A 79-year-old Iranian man resident in Eird-e-Mousa village from Ardabil Province, north-west of Iran, complained with abdominal pain, nausea, and intestinal obstruction symptoms referred to Ardabil Fatemi hospital. In laparotomy multiple intestinal masses with peritoneal seeding resembling of a malignant lesion were seen. After appendectomy and peritoneal mass biopsy with numerous intraperitoneal adenopathy, paraffin embedded blocks were prepared from each tissues. A blood sample was taken from the patient 5 months later for serological diagnosis. Histopathological examination of sections showed fibrofatty stroma with dense mixed inflammatory cells infiltration and fibrosis in peritoneal masses. Large numbers of ova of Fasciola spp. were noted with typical circumscribed granulomas. Despite of anti-fasciola treatment, IHA test for detecting anti F. hepatica antibodies was positive 5 months after surgery with a titer of 1/128. Due to multiple clinical manifestation of extra-hepatic fascioliasis, its differential diagnosis from intraperitoneal tumors or other similar diseases should be considered.
