title: Atypical presentation of Crohn's disease: severe, recurrent iron deficiency anemia dependent on blood transfusions.
abstract: We report an unusual case of Crohn's disease. Our subject, a 43-yr-old lady, presented with severe iron deficiency anemia, hypoproteinemia and lymphocytopenia, but without any clinical manifestations of Crohn's disease either at presentation or during follow-up. She had recurrent episodes of severe iron deficiency anemia, repeatedly requiring blood transfusions (28 units in 20 months). She was found to have a short stricture with ulceration in the ileum due to Crohn's disease, and a blind loop with bacterial overgrowth above it. Resection of the affected area prevented further recurrence of anemia and corrected hypoproteinemia. We postulate that her anemia and hypoproteinemia were due to blood and protein (lymph) loss from the ulcerated area in the ileum. Such a presentation has not been described before.
