toxocariasis or visceral larva migrans (vlm) is a parasitic infection resulting from the invasion of human visceral organs by nematode larvae of genus toxocara (dog ascaris). using gathered information of clinical manifestations, past history, biochemical and haematological tests, indirect fluorescence antibody test (ifa) and follow up of patients, totally 10 human cases (6 males and 4 females)...

background : the visceral larva migrans (vlm) is a syndrome observed in human infection with helminth larval eggs such as the toxocara spp. that usually infects dogs and cats. among the risk factors involved in the occurrence of vlm, partic­ularly importance of these animal populations, an investigation was carried out for the presence of toxocara spp. eggs in public parks in the city of urmia,...

the presence of visceral larva migrans (vlm) in a patient is reported. a 57-year- old woman suffering from right upper abdominal and suprapubic pain referred into a clinic in khorramabad, lorestan province, iran. a cystoscopy was performed and biopsy was taken. the light micro­scopic study showed a couple of larvae as well as mononuclear inflammatory cell- infiltration. because occurrence of vl...

While the incidence ofmany parasitic diseases has decreased because of the development of anthelmintics and environmental hygiene, infection by Trichuris still occurs. This parasite exhibits some special parasitological and clinical features. Beaver et al introduced the term visceral larva migrans in the case of toxocariasis.' While the visceral larva migrans syndrome has been reported to be ca...

We report a case of visceral larva migrans in an adult with fever, night sweats, weight loss, hilar and mediastinal lymphadenopathy, bilateral pleural effusion, and eosinophilia-mimicking lymphoma. Visceral larva migrans was diagnosed subsequently because of negative findings for malignancy and positive serologic test result for Toxocara canis. Progressive improvement was observed with albendaz...

background: human toxocariasis, a helminthozoonosis, is due to the migration of toxocara species larvae into human organisms. humans, especially children become infected by ingesting of embryonated eggs from soil, dirty hands, and raw vegetables. seroprevalence of this infection is high in developed countries, especially in rural areas. the aim of this study was to investigate the seroepidemiol...

We present a case of visceral larva migrans which came as a complete histologic surprise. The patient was operated as a case of chronic cholecystitis and was found at operation to have multiple hepatic nodules. A cholecystectomy with a biopsy of the liver nodule was performed. Histopathologically a diagnosis of visceral larva migrans was made. To our knowledge this is the first case report of t...

There are many causes of persistent eosinophilia in children, but Perlingiero and Gyorgy (1947) described a case in which there was also hepatic enlargement, anaemia and fever. Two years later Zuelzer and Apt (1949) described eight similar cases and suggested that they formed a definite syndrome. Since then several more have been reported and it has been shown that this syndrome is frequently c...
