title: Coexistence of symptomatic iron-deficiency anemia and duodenal nodular lymphoid hyperplasia due to giardiasis: case report.
abstract: Iron-deficiency anemia due to iron malabsorption and duodenal nodular lymphoid hyperplasia (NLH) has been described in children with Giardia intestinalis infection. Also, symptomatic iron-deficiency anemia is rarely encountered in male adolescents. A 14-year-old boy underwent esophagogastroduodenoscopy for investigation of symptomatic iron-deficiency anemia (hemoglobin 5.8 g/dL, mean corpuscular volume 65.3 fL, serum ferritin < 1.5 ng/mL). He had a sufficient diet for iron and recurrent bouts of diarrhea without melena. At upper endoscopy, duodenal mucosa was diffusely nodular. Histopathologic evaluation of biopsy samples from the duodenum revealed infection with Giardia intestinalis. His anemia improved with metronidazole and iron treatment.
