Visceral Larva Migrans: A Rare Encounter by a Cytologist
Asian Journal of Research in Infectious Diseases,
VLM is a zoonotic disease caused by the migration of third-stage larvae of nematodes through the tissue of human viscera. Among various etiological agents such as Baylisascaris procyonis, Capillaria hepatica, Ascaris sum, and some Ancylostoma species, Toxocara is a major cause of VLM. Poor hygiene, contact with dogs and geophagia increases the risk of toxocariasis.Young adults and children who are in close contact with animals are at a higher risk. Here we present a case of 7 years male child presenting with fever, abdominal pain and vomiting. The clinical presentation, biochemical and radiological findings supported the diagnosis of VLM which was corroborated in the cytological examination. Here we report a rarest encounter of VLM in the cytology smear.
