Abstract:
Giardia lamblia is the most common human parasite with a worldwide distribution and fecal-oral way of transmission. Diagnostic procedures include stool examination and gastroduodenoscopy with biopsy or secret aspiration. In most cases histology reveals a dense accumulation of the parasites on the surface of the duodenal mucosa with no or only slight inflammation. In rare cases, a dense inflammatory infiltrate with severe mucosal atrophy and increased count of intraepithelial lymphocytes may be seen. If in such cases the amount of parasites is low, the histological picture may mimic celiac disease. The two presented cases demonstrate the close morphological relationship and show the importance of considering giardiasis in the differential diagnosis in patients with suspected celiac disease.
