Lung tumors are abnormal growths, which can be classified as either cancerous (malignant) or benign (noncancerous). Several studies have shown that benign lung tumors are usually asymptomatic and do not pose a significant health problem. Building on this idea, the growths are often found during an imaging test performed for other reasons, such as chest X-ray. The primary goals of surgical intervention for patients with benign tumors of the lung and bronchus are to alleviate symptoms, obtain a histologic diagnosis, rule out malignancy, and preserve functioning lung tissue. In this case report, a 52-year-old female patient presented to the hospital with a chief complaint of productive cough and shortness of breath. Thoracic computed tomography (CT) scan showed a tumor mass in the left lung, while a biopsy through bronchoscopy revealed lung tissue with inflammation accompanied by fibrinoid necrosis. The biopsy results also showed the absence of malignancy. Subsequently, a lobectomy surgery was performed to remove the lower lobe of the left lung, leading to significant improvement in the patient’s complaints.
