Benign Metastasizing Leiomyoma

Benign Metastasizing Leiomyoma (BML) is a rare disease characterized by proliferation of uterine smooth muscle tissue in extrauterine locations. The lungs are the most affected organ. The patient type is a female in the pre/ perimenopausal age that has been gone through a myomectomy several years before when during a routine chest roentgenogram multiple pulmonary shadows are noticed. We report a case of a 54-years-old female who presented a chest X-ray with multiple bilateral pulmonary nodules during a health checkup. She had no symptomatology and personal history just included uterine leiomyomectomy of the uterus 16 years before. A contrast-enhanced CT confirmed the nodules within a normal interstitium. A biopsy was performed and histopathological examination showed characteristics of smooth muscle cell differentiation giving the diagnosis of BML. The management strategy decided was just radiological follow-up and she is stable ever since.
