Pulmonary leiomyoma is a rare lung tumor and comrises 2% of benign lung tumors. We herein report two cases of parenchymal pulmonary leiomyoma that we encountered recently. In case 1, an asymptomatic 47-year-old male was found to have a pulmonary nodule in the right upper lung field on screening chest X-ray. He was hospitalized for thoracoscopic removal of the tumor. Microscopic findings revealed that the tumor was pulmonary leiomyoma. He has remained well since surgery and there is no evidence of tumor recurrence to date. In case 2, a 45-year-old female, who had undergone hysterectomy 17 years earlier for uterine leiomyoma, was found to have a pulmonary nodule in the left lower lung field on screening chest X-ray. She was hospitalized and chest computed tomography scan showed another small nodule in the right lower lobe. The left pulmonary nodule was resected by thoracoscopic surgery, and diagnosed as pulmonary leiomyoma pathologically, although the possibility that her tumor might be benign metastasizing leiomyoma from previous uterine leiomyoma could not be ruled out. Right lung nodule was so small that we decided not to remove that tumor at this time. Therefore, meticulous follow-up of this case is mandatory.
