[Neoplastic pulmonary embolism. Apropos of a case diagnosed by transbronchial pulmonary biopsy]

The authors report a case of micro-pulmonary emboli of malignant cells observed in a 58 year old lady who had been submitted to a mastectomy for cancer 18 months before, followed by chemotherapy for six months. The patient entered into the terminal phase of her disease with dyspnoea which became rapidly incapacitating leading to her death ten weeks later, in spite of heparin therapy and chemotherapy. The diagnosis was furnished by a transbronchial biopsy. However, the discovery of a mobile mass in the right ventricle raised the question as to the source of the micro-emboli.
