Chemoreceptor tumors, also known as non-chromatid paraganglioma, occur in 98% of carotid bodies and jugular veins, and are rare in primary lungs. Only 2 cases have been reported in China. We diagnosed and treated a case with the following report: The patient was male, 20 years old, Sichuanese, hospital number 71645. Left chest pain occurred five months ago, not related to cough or breathing. Local hospital X-ray findings of the left lower lobe shadow, and in April 11, 1985 into our hospital for surgery. Physical examination: body temperature 36.7°C, pulse 70 beats/min, breathing 18 beats/min, blood pressure 122/68 mmHg. In general, the left chest is full, no tenderness and percussion pain, and no vocalization is heard. Vascular murmurs and pleural fricatives. No abnormalities were detected in routine tests and ECG was normal. The X-ray film showed a round block with a uniform density, smooth edges, and a diameter of about 4 cm. The lower edge of the X-ray film was close to the left temporal surface. The shape of the tumor did not change during deep breathing and was diagnosed as benign lung tumor. Tracheotomy underneath the tracheal anesthesia on April 17, 1985, with a lump under the left lung
