ABSTRACT Visceral larva migrans is a disease produced after the ingestion of infectant eggs of cat´s and dog´s nematode parasites (Toxocara canis and Toxocara cati). These parasites harch in the men´s intestines and the larvas are distributed around the organism, mainly in the following organs: liver, lungs, hearth and brain. In their migration, the larvas leave traces of hemorrhage, necrosis and inflammatory cells; several of them are destroyed by the host´s immune answer and others form eosinophilic granulomas. The symptoms depend on the affected tissue or organ, on the infection intensity and on the level of induced immunologic answer. The case of a male patient, aged 72 years-old is presented. He entered the Medicine Service of the Teaching Military Hospital “Dr. Mario Muñoz Monroy”, of Matanzas with fever, diarrhea, dry cought, asthenia, anorexia and weight loss.Visceral larva migrans was diagnosed. The presentation of the case was decided because of the atypical patient´s age and the complexity of the diagnosis.
