The classic presentation of celiac disease includes symptoms of malabsorption but has long been associated with cognitive, emotional, and behavioral disorders. We describe an 8-year-old patient with nonscarring alopecia and diagnosed with trichotillomania. Furthermore, she presented with a 3-year history of poor appetite and two or three annual episodes of mushy, fatty stools. Laboratory investigations showed a normal hemoglobin concentration and a low ferritin level. Serologic studies showed an elevated tissue immunoglobulin G anti-tissue transglutaminase level. A duodenal biopsy showed subtotal villous atrophy and crypt hyperplasia, and a large gastric trichobezoar was found in the stomach. Immediately after beginning a gluten-free diet, complete relief of trichotillomania and trichophagia was achieved. In this report, we describe a behavioral disorder as a primary phenomenon of celiac disease, irrespective of nutritional status.展开更多
