RESUMEN
Benign metastasizing leiomyoma is usually detected years after hysterectomy or myomectomy and characterized by well-circumscribed, singular or, often, multiple nodules. The patient was a 33-year-old woman who presented with cough. She underwent a myomectomy for a large uterine leiomyoma 9 years ago. And now she has recurrent uterine myoma. Multiple nodular lesions in both whole lung fields were incidentally found on a routine chest radiograph. Video-assisted thoracoscopy (VATs) was performed. The resected small nodular lesions composed of extremely well- defferentiated smooth muscle cells with collagen. On immunohistochemical stain, they are positive for smooth muscle markers (desmin and actin). There is no definite evidence of malignancy. Therefore, these multiple nodules are considered as benign metastasizing leiomyoma from a uterine leiomyoma. We report this case with review of literatures.
