Abstract
CASE PRESENTATION: A 64-year-old woman with known metastatic lobular breast cancer presented with fever, epigastric pain, hematemesis, and melena. A bleeding, ulcerated gastric metastasis was found and was treated with endoscopic therapy, omeprazole, and hormonal therapy. The patient was alive and well 13 months later. The bleeding was probably precipitated by necrosis of the lesion during chemotherapy. DISCUSSION: Gastrointestinal tract metastases from primary breast carcinoma are present in 14% to 35% of cases in autopsy series, with gastric involvement in 6% to 18% of cases. Recognized much less commonly during life than in autopsy studies, they can occur anywhere in the gut and can mimic virtually any gastrointestinal disorder. Endoscopy and barium studies facilitate diagnosis. Gastric lesions that have been noted include "linitis plastica", nodules, polyps, and ulcers. They are usually due to lobular breast carcinoma and resemble primary gastric carcinoma on microscopy. Reported cases of bleeding gastric metastases have been treated successfully with various local and systemic modalities. The median survival time of reviewed cases was four months from presentation (with a range of zero to 24 months). CONCLUSIONS: Gastrointestinal metastasis is an underdiagnosed complication of breast cancer. Gastrointestinal bleeding from metastatic breast cancer is an uncommon presentation that is readily diagnosed and that can be treated successfully by endoscopic hemostatic therapy.
