Core Tip
Core tip: Myeloid sarcoma rarely presents in the gastrointestinal tract. Rarer still, does myeloid sarcoma manifest in the gastrointestinal tract without systemic involvement by a myeloid neoplasm. This case report documents the first instance in the English literature wherein an isolated extramedullary site of myeloid sarcoma adopting the form of a colonic polyp was found to be a harbinger of chronic myelogenous leukemia.
