Robotic-assisted right middle lobectomy for poorly differentiated squamous cell carcinoma

The patient, a 73-year-old men, was admitted due to “sputum with blood for one month” and “mass in the right middle lung lobe”. One month ago, he developed cough and expectoration with blood-stained sputum. Two weeks ago, chest CT showed a soft-tissue mass with irregular border in the lateral segments of the right middle lung lobe. Bronchoscopy detected a mass at the bronchial orifice in the lateral segments of the right middle lung lobe. No malignant cell was detected at biopsy pathology. The patient’s complaints did not include low fever, night sweats, nausea, vomiting, abdominal distension, diarrhoea, heart palpitations, or discomfort of precordial area. His mental status, physical performance, appetite, and sleep were normal, and the body weight did not obviously change. Urination and defecation were normal.
