We describe a patient with breast cancer who relapsed with an extensive pulmonary lymphovascular tumor embolism. A 38-year-old female, who previously received neoadjuvant chemotherapy and curative resection of breast cancer, underwent adjuvant chemotherapy and was referred to the emergency room because of sudden-onset pleuritic chest pain lasting for 10 days. Despite a trial of empirical antibiotics, the chest pain and the extent of consolidative lung lesion on chest radiographs rapidly aggravated. We performed an open lung biopsy to confirm the etiology. The histopathological review revealed a hemorrhagic infarction caused by lymphovascular tumor emboli from a metastatic breast carcinoma. Palliative first-line chemotherapy was administered, consisting of ixabepilone and capecitabine, and the lung lesion improved markedly.
