[Atypical anisakiasis in acquired immunodeficiency syndrome]

Gastric anisakiasis was an incidental finding on gastroscopy of a 48-year-old man known to have AIDS. At that time the patient had been symptom-free, the test having been performed to check on an ulcerative Candida oesophagitis. The Anisakis larva was extracted through the gastroscope and there has been no recurrence. The history suggested a chronic course. The unusual absence of symptoms suggests that the immunodeficiency had influenced the pathogenesis of the parasitic disease.
