title: A Rare Case of Phyllodes Tumor Metastasis to the Stomach Presenting as Anemia.
abstract: Metastasis of a phyllodes tumor to the stomach is an extremely rare condition with important clinical implications. A 44-year-old woman was initially diagnosed with a phyllodes tumor in her right breast in 2008, and subsequently presented to an outpatient clinic with dizziness on December 16, 2013. We found that she had severe anemia (hemoglobin levels, 6.7 g/dL), and we quickly performed esophagogastroduodenoscopy to identify the cause. This procedure revealed large ulcerofungating masses with active bleeding in the stomach. Histopathological examination revealed that the masses were consistent with phyllodes tumor metastases. In patients with a metastatic phyllodes tumor presenting as anemia, gastric metastasis should be considered as one of the differential diagnoses because overlooking the possibility might have dire consequences if cytotoxic chemotherapy were administered.
