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 out-patient 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.

  Fig. 1. Initial histopathological findings from 2008: a phyllodes tumor in the right breast (H&E staining, ×100).

  Fig. 2. Esophagogastroduodenoscopic findings: a large ulcerofungating mass in the lower body-angle (A) and the cardia side of the gastroesophageal junction on the lesser curvature (B).

  Fig. 3. Esophagogastroduodenoscopic biopsy and histopathological examination revealed sarcoma-like features that consisted of short spindle cells, which are characteristic of phyllodes tumor, and ulcerofungating gastric masses consistent with metastasis from a phyllodes tumor (H&E staining, ×100).
