Easy to be confused with lung diseases signal

Easy to be confused with lung diseases are tuberculosis, pneumonia, lung abscess, lung benign tumor Mucormycosis
(1) Tuberculosis: diagnosis of lung cancer and tuberculosis most confused. Tuberculoma, hilar lymph node tuberculosis, acute miliary tuberculosis, hollow shape, such as pleural effusion TB change, can be very similar to lung cancer.
Tuberculoma was particularly prevalent in young patients with TB lesions at a good site (apex, the leaves and under the dorsal posterior segment), the border clear, and sometimes contains calcifications, often around the satellite kitchen. If so empty formation, while as the center empty, thin wall, rules, can be found in sputum Mycobacterium tuberculosis. These features and peripheral lung cancer can be differential.
Hilar lymph node tuberculosis and central lung cancer easily confused, but the former were more common in children or young people, many TB poisoning symptoms such as fever, tuberculin test positive, effective anti-TB treatment.
Acute miliary tuberculosis with diffuse alveolar carcinoma phase identification. The former patients younger fever and other symptoms of systemic poisoning, X-ray on the see-distributed, small, light density of miliary nodules on both sides of symmetry, often accompanied by toxaemia. And diffuse alveolar carcinoma size两肺see Disseminated nodular lesions, border clearance, the density of the deep, progressive development of the expansion of clinical sexual difficulty breathing.
Tuberculous pleural effusion by pleural effusion out mostly yellow, hydrothorax can identify Mycobacterium tuberculosis, and malignant pleural effusion is mostly blood, which can be found in cancer cells.
(2) pneumonia: cancer should be to identify obstructive pneumonia. Sharp onset of pneumonia, there shivering, fever and other symptoms毒血, and then respiratory symptoms, antibiotic therapy effective, rapid absorption of lesions, rare hemoptysis, and obstructive pneumonia cancer inflammatory infiltration slow absorption, absorption is not complete, often hemoptysis. But the most reliable methods of identification for sputum cytology examination or bronchoscopy.
(3) pulmonary abscess: with cancer empty secondary infection phase identification. Primary pulmonary abscess acute onset, poisoning symptoms, often high fever, chills, cough, sputum pyronaridine stinking lot of pus, blood cells and neutrophils increased. See the X-ray thin hollow wall with a fluid level, surrounded by inflammatory changes. The first empty cancerous lung cancer symptoms such as chronic cough, sputum blood repeatedly, and then cough aggravated脓痰number. See chest cancer are eccentric empty mass, wall thickness, wall surfaces. Sputum cytology and bronchoscopy can be further identification.
(4) benign lung: is characterized by fewer symptoms, course length, X-ray on the brink of mass see smooth, rare sub-leaf density, calcifications were petal-like structure. Such as chondroma, hamartoma, such as benign lipoma. If growth in the bronchial lumen can have obvious symptoms, but a longer course of disease and lung cancer different.
(5) pulmonary aspergillosis: in the chest was often accompanied by mass around the sub-stoves, there were often empty formation of a single small-form-like; a diffuse disease often showed a small mass and distribution of asymmetry on both sides. Sputum culture-shaped bacteria often Minowa or Candida albicans.  lung metastasis What are the symptoms
Malignant lung is the highest organ fat, according to statistics about 50% of malignant tumors spread through direct infiltration, airway cultivation, lymphatic metastasis and blood to the lungs, cough, hemoptysis or血痰, chest pain, if the tumor metastasis to the bronchial has been the subject of obstructive pneumonia and atelectasis, fever, chest tightness, dyspnea and other symptoms.
