Hemoptysis is due to respiratory diseases, such as tuberculosis, bronchiectasis, pneumonia, lung abscess, lung cancer, etc. This is followed by cardiovascular diseases, such as rheumatic waive heart valve disease, mitral stenosis, etc. In addition, epidemic hemorrhagic fever, leptospirosis, pulmonary schistosomiasis, leukemia, thrombocytopenic purpura, etc. may also cause hemoptysis. Bleeding from nasopharyngeal carcinoma tumor may also cause a symptom of coughing up blood. You can check chest X-ray, CT, sputum culture, sputum for tuberculosis bacteria (if there is a previous history of tuberculosis more should focus on screening), laryngoscopy, bronchoscopy, etc. for clarification. Patient: April 2010 Occasional coughing of blood for six months, recently worsened. I want to confirm what disease laboratory and examination results: CT has been done and calcified spots were found .
