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.

Benign metastasizing leiomyoma (BML) is a rare entity, characterized by the occurrence of multiple smooth muscle nodules in the lung with histologically benign leiomyoma, Both the uterine and pulmonary tumors have been found to express estrogen and progesterone receptors, which suggest that the pulmonary lesions represented metastases from leiomyoma. We experienced a 41-year-old female patient with BML and report here with the literature review.

Intravenous leiomyomatosis of the uterus is a rare tumor that presents with benign histological features. It is characterized by intravenous proliferation of smooth muscle cells originating from the uterus that sometimes extends to the inferior vena cava and the right heart. It may spread elsewhere, usually to the lung. The first case of intravenous leiomyomatosis was described in 1896 by Birsh-Hirshfeld, and only a few cases have been reported since then. Its pathogenesis and optimal treatment have not yet been established. We report a case of metastasizing leiomyomatosis found to have multiple nodular densities in both lower lung fields seven months after myomectomy. In another case the leiomyomatosis was confined to the pelvis after a laparoscopy assisted vaginal hysterectomy, the patient is alive without evidence of disease. Here we provide a detailed report of two cases of intravenous leiomyomatosis of the uterus with a brief review of the literature.

Leiomyoma of the bronchus is a very rare benign tumor of the lung. Most endobronchial leiomyomas occur as secondary foci of primary uterine leiomyoma. We herein report a case with endobronchial tumor that had a different pathology from a primary resected uterine leiomyoma and was therefor considered a primary endobronchial leiomyoma. A 51-year-old woman with a history of uterine myoma presented with productive cough and fever. Bronchoscopy revealed a lightly yellow colored mass lesion that totally obstructed the orifice of the left lower lobe of the lung. The diagnosis of leiomyoma was made by histological examination of the obtained specimen. We considered the possibility of a benign metastasizing pulmonary leiomyoma. For treatment and differential diagnosis, a left lower lobe lobectomy of the lung and total hysterectomy with bilateral salphingooopherectomy were performed. The differences between lung and uterine lesions were confirmed by morphologic finding and immunohistochemical staining. The pathological diagnosis was primary endobronchial leiomyoma combined with uterine myoma.
