Iron Deficiency Leading to the Diagnosis of a Rectal Neuroendocrine Tumor: A Case Report

Abstract

Iron deficiency is common, particularly in young women, but persistent cases that do not respond to treatment require further investigation, especially within the gastrointestinal system. In this case report, we present a 35-year-old woman with chronic intermittent pruritus for 2 years and refractory iron deficiency ultimately diagnosed with a rectal neuroendocrine tumor (NET). After the tumor was identified through colonoscopy and pathology report, she underwent surgery, which led to the disappearance of pruritus and improvement in ferritin levels. This case underscores the importance of considering systemic causes for persistent pruritus and refractory iron deficiency, highlighting the need for comprehensive evaluation.
