Abstract

We report here a case of pulmonary benign metastasizing leiomyoma from the uterus in a 45 year old woman. The patient presented for investigation of multiple pulmonary nodules on a routine chest roentgenogram. The patient had undergone uterine myomectomy due to uterine leiomyoma 10 years earlier. We performed thoracoscopic wedge resection for definitive diagnosis. Histologically, spindle shaped smooth muscle cells appeared between collagen stroma, histology similar to that seen in uterine myoma. The tumor tissue tested positive for estrogen and progesterone receptors. The pathological findings were consistent with benign metastasizing leiomyoma. The patient was in pre-menopause. She received no specific treatment for lung tumors, and we did not found any changes in the lesions after one year follow up without any medication.

양성 전이성 평활근종은 조직학적으로는 양성이나 임상적으로 폐나 다른 장기로 원격전이를 하는 매우 드문 질환이다. 저자들은 10년 전 자궁평활근종 절제술을 시행한 환자의 폐에서 발견된 다발성 결절 일부를 흉강경 수술하에 절제하여 조직학적 및 면역염색검사로 양성 전이성 평활근종임을 진단할 수 있었다. 환자는 수술 후 종양의 크기 변화 및 특이 증상이 없으며 특별한 치료 없이 외래 추적관찰 중이다.
