Celiac Disease Presented as Plummer–Vinson Syndrome: A Case Report

Background and Clinical significance: Plummer–Vinson (PV) syndrome is a rare medical entity diagnosed when iron-deficiency anemia, dysphagia, and esophageal webs occur in the same patient. PV syndrome has been associated with different autoimmune diseases, such as celiac disease (CD). CD is a chronic multisystemic disorder affecting the small intestine, but it is recognized as having a plethora of clinical manifestations secondary to the malabsorption syndrome that accompanies the majority of cases. However, similar to PV syndrome, a high percentage of CD patients are asymptomatic, and those who are symptomatic may present with a wide variety of gastrointestinal and extraintestinal symptoms, including iron-deficiency anemia, making the diagnosis challenging. Case presentation: We present the case of a 43-year-old Caucasian female patient with a 7-year history of iron-deficiency anemia and increased bowel movements (3–4 stools/day). Upper endoscopy demonstrated a narrowing at the proximal cervical esophagus from a tight esophageal stricture caused by a smooth mucosal diaphragm. A 36F Savary–Gilliard dilator was used to manage the stenosis. The distal esophagus and stomach were normal, but scalloping of the duodenal folds was noted, and CD was confirmed by villous atrophy and positive tissue transglutaminase antibodies. Dysphagia was immediately resolved, and a glute-free diet was implemented. Conclusions: The relationship between PV syndrome and CD is still a matter of debate. Some might argue that PV syndrome is a complication of an undiagnosed CD. In cases of PV syndrome, a CD diagnosis should be considered even in the absence of typical symptoms of malabsorption.
