Question: A 31-year-old woman, born in Pakistan, presented with dysphagia and severe anemia. She had a 10-year history of iron deficiency anemia secondary to chronic menorrhagia. She initially received a red blood cell transfusion, but had no gynecologic explorations or follow-up. The patient complained of dysphagia for solids that had been worsening for the last 5 years associated with a weight loss of 10 kg, but not with odynophagia or dysphonia. At admission, her hemoglobin level was 55 g/L, with a low mean corpuscular volume ( 70fL) and ferritin level (<10 mg/L). Oral clinical examination, nasopharyngeal endoscopy and cervical computed tomography scan were normal. A barium swallow (Figure A, B) and gastroscopy (Figure C) were performed.What is the diagnosis?
