ABSTRACT
A 77 year-old male was admitted with the symptom of palpitations on exertion. A tumor lesion was observed in cardiac ultrasonography. Several examinations led to the diagnosis of lung carcinoma with the complication of left-atrial invasion. Following the patient's will, and considering various side effects of chemotherapy, we performed only palliative care, including whole-brain irradiation therapy for brain metastasis. As a result, comparatively long-term survival was acquired, and lastly we diagnosed combined small cell lung carcinoma by autopsy. It is reported that patients having lung carcinoma with cardiac invasion are at high risk of sudden death by complications of various cardiac diseases. This case suggests that we must consider the possibility of lung cancer, even when patients show only cardiac symptoms.
