Toxocara canis infection and granulomatous hepatitis.

This report describes possible involvement of Toxocara canis in granulomatous hepatitis in three patients who presented with varied clinical features; two were being treated for other diagnoses until Toxocara serology became available. Despite initial nonspecific therapy, there was clinical improvement in all patients and complete resolution of symptoms and abnormal liver biochemistry in two. T. canis infection should be considered in cases of granulomatous hepatitis.
