  • Benign metastasizing leiomyoma(BML) is a rare condition affecting women with a history of having undergone hysterectomy or myomectomy for a benign uterine fibroid, that is found to have metastasized to extrauterine sites, usually many years after hysterectomy. 1,2) Patient with BML almost always asymptomatic, although if the lesions are large enough, they can cause compressive symptoms. Among several hypothesis of pathogenesis, most plausible theory is that these tumors represent a true metastatic lesion but are very low-grade sarcoma. 3) Because the tumor is responsive to estrogen, menopause and pregnancy have slowed the growth of these lesion 4) and it seems reasonable to perform hysterectomy in patients with a uterine mass and, at the same time, perform oophorectomy for hormonal control. BML is an unusual cause of diffuse pulmonary nodules which should be considered in females with unexplained nodules and a history of surgery for uterine leiomyoma.

  • A benign pulmonary metastasizing leiomyoma is a recognized clinical entity that has been infrequently reported in the medical literature. We report two cases of a benign pulmonary metastasizing leiomyoma. A 35-year-old woman who underwent myomectomy and a cesarean section approximately 6 years earlier visited our hospital for further evaluation of incidentally revealed multiple lung nodules. A diagnostic percutaneuous biopsy was performed. Finally she was diagnosed with a benign metastasizing leiomyoma. The patient then received LH-RH and has been followed up since. The other 44-year-old woman presented after an initial radiology evaluation revealed the presence of multiple, small-sized lung nodules. She underwent a right middle lung wedge resection to confirm the diagnosis. Finally she diagnosed with a benign metastasizing leiomyoma. The multiple lung nodules have been followed up closely.

  • A benign metastasizing pulmonary leiomyoma(BMPL) is a rare disease that is usually detected years after a hysterectomy or myomectomy. Despite the benign pathological appearance, these tumors can metastasize and become clinically malignant. Recently, we experienced case of BMPL with hemoptysis. A 43-year-old woman, who had undergone a hysterectomy due to uterine leiomyoma 8 years ago, visited our department complaining of intermittent hemoptysis. A chest CT showed bilateral multiple nodular lesions. Video-associated thoracoscopy was performed. The resected small nodular lesion revealed the proliferation of spindle cells without mitosis or nuclear atypism. The lesions tested positive to the smooth muscle marker (actin) by immunohistochemical staining. Therefore, the multiple nodules were considered as benign metastasizing pulmonary leiomyoma from a uterine leiomyoma. GnRH analogue therapy was initiated. A chest CT showed that the size and number of pulmonary lesions did not change after 3 months, and the patient was symptom free.

  • A benign metastasizing pulmonary leiomyomatosis(BMPL) is a rare and uncommon variety of leiomyoma. BML affects middle-aged women who had a previous hysterectomy due to a histologically benign appearing leiomyoma. BMPL is characterized by asymptomatic multiple smooth muscle nodules with a less aggressive course than a leiomyosarcoma. A 45-year-old woman who had a hysterectomy for a uterine leiomyoma 4 years prior to this study presented with multiple variable-sized lung nodule. A percutaneous needle biopsy confirmed the benign metastasizing pulmonary leiomyomatosis. Here, we present this case with a review of the relevant literatures.

  • A benign metastasizing pulmonary leiomyoma (BMPL) is a rare disease that usually occurs in women with a prior or coincident history of uterine leiomyoma. Although leiomyoma is histologically benign, it has the potential to metastasize to a distant site such as the lung. A 35 year old woman who had undergone a hysterectomy due to uterine leiomyoma 5 years prior was admitted for an investigation of multiple pulmonary nodules on a routine chest roentgenogram. An open lung biopsy was taken to make a pathological diagnosis. The microscopic finding of the nodules was leiomyoma and was similar to those of the uterine leiomyoma that had been resected 5 years ago. The woman underwent wedge resections of all pulmonary nodules. This is the first case of BMPL in Korea, which was treated with wedge resections of all multiple pulmonary nodules.

  • Pulmonary benign metastasizing leiomyoma (PBML) is defined as metastasis of a leiomyoma to lung tissue. It was first reported in 193 7. PBML is known as a benign disease, but can undergo malignant transformation. Only 1 case of the malignant transformation of PBML to leiomyosarcoma has been reported previously. In this report, we present a case of malignant transformation of PBML.

  • Benign metastasizing leiomyoma (BML) is a rare disease, which usually occurs in women with a history of a prior hysterectomy or myomectomy for benign uterine leiomyoma, and has the potential to metastasize to distant sites, such as the lung, lymph nodes, muscular tissue, heart, or retroperitoneum. These lesions are slow-growing, asymptomatic, and usually found incidentally. The prognosis of BML is also excellent. However, there has been debate on the origin and the correct classification of BML, and there are no guidelines for the treatment of BML. We report here on a rare case of BML in both the retroperitoneal cavity and lung in a 48-year-old woman with a history of hysterectomy due to histologically benign uterine leiomyoma. The patient underwent retroperitoneal mass excision and bilateral salpingo-oophorectomy, and then wedge biopsy of two pulmonary nodules was performed additionally 9 days later. Until now, there has been no sign of recurrence and the patient remains asymptomatic. To our knowledge, pulmonary BML is rare and the co-existence of the retroperitoneal metastases after previous hysterectomy is even rarer.

  • 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 is a rare disease that histologically shows features of a benign tumor; however it can metastasize to the lung or other organs. We report here on a case of a 53-year-old Woman with benign metastasizing leiomyoma, and she was admitted to the hospital with symptoms of coughing for 2 months; she showed multiple diffuse nodular opacities of both lungs on a chest radiograph. She had undergone hysterectomy for leiomyoma of the uterus 13 years previously. Thoracoscopic lung biopsy was performed to rule out metastatic lung cancer. The pulmonary nodules appeared benign with a very low mitotic rate and they consisted of smooth muscle cells. The pathologic findings of the pulmonary nodules were consistent with benign metastasizing leiomyoma. The patient has been followed up closely without any specific therapy.

  • We performed thoracoscopic resection for diagnosis in 41 year-old-female presenting with multiple pulmonary nodules in both lung fields, which was detected incidentally on routine chest x-ray and followed by additional exmaminations including chest CT scan and percutaneous needle aspiration biopsy under the presumptive diagnosis of metastatic cancer. During thoracoscopy, the result of the frozen section analysis of multiple masses revealed strong evidence of leiomyoma. In her past medical history, she had undergone myomectomy, and hysterectomy, 7 year ago and 10 year ago, respectively. Based on permanent, special staining of specimen, estrogen receptor assay and review of past specimen of uterine myoma the final diagnosis was benign metastasizing leiomyomata from uterine myoma, the report was very uncommon in Korean and English literatures. The patient has been followed up for 2 year without special therapy, such as hormonal therapy.
