Primary pulmonary leiomyosarcoma: A case report

Abstract

Primary pulmonary leiomyosarcoma (PPL) is an extremely rare malignant tumor. It has been revealed that PPL may originate from the smooth muscle of the pulmonary parenchyma, pulmonary arteries and bronchi. Patients with PPL may be asymptomatic or present with symptoms similar to those observed in other primary lung tumors. The present study reports the case of a 48-year-old man who presented with a lung mass and underwent a right upper-middle lobe bronchoscope tumor resection. The patient was subsequently diagnosed with PPL. Following the bronchoscopic tumor resection, chemotherapy was administered to the patient; however, the patient succumbed to the disease after the second cycle of chemotherapy.
