[Larval toxocariasis in a 40-year-old man with detection of larvae in a liver biopsy]. / Larvální toxokaróza u 40letého muze s prukazem larvy v biopsii jater.

A 40-year old cattle feeder has been suffering from indigestion, leukocytosis and conspicuous eosinophilia for about 4 years. A sample of liver tissue was taken during gastrectomy and multiple allergic granulomas rich in eosinophilia leukocytes were found. Toxocara canis was identified in serial sections outside the granulomas. Larval toxocariasis was confirmed by a high level of specific antibodies which failed to decrease even after administration of Mintezol antithelmintic. In this country, there was serological proof of 287 cases of larval toxocariasis till July 1982. This is the first finding of Toxocara larvae in liver biopsy published in Czechoslovak literature. Another finding of liver Toxocara larvae was made in a 86-year old woman included among 4 cases of allergic granulomatosis of the liver published before.
