Unmasking the Silent Culprit: Gastric Neuroendocrine Tumor in the Setting of Iron Deficiency Anemia.

Gastric neuroendocrine tumors (GNETs) are uncommon neoplasms; it is classified into four subtypes based on low to high risk of progression and developing metastasis. GNETs can be asymptomatic or present with nonspecific signs and symptoms, including dyspepsia and iron deficiency anemia (IDA). In people who menstruate, iron deficiency is often attributed to menstrual cycles, and they may not undergo investigation for gastrointestinal sources. We present a case of a young female with long-standing iron deficiency and menorrhagia, who was found to have a rare GNET, most consistent with a type 3 subset.
