INTRODUCTION Benign metastasizing leiomyoma in the lung is a very rare disease characterized by the growth of uterine leiomyoma tissue. In most cases there is a previous history of hysterectomy for uterine leiomyoma. CASE PRESENTATION A 50-year-old Asian woman underwent a total abdominal hysterectomy for uterine leiomyoma at the age of 37 years old. She was referred to our hospital because of...

Benign metastasizing leiomyoma (BML) is composed of well-differentiated smooth muscle cells and dense connective tissue. BML affects middle-aged women who have had previous hysterectomies due to a histologically benign-appearing uterine leiomyoma. We report here on a case of BML from the uterine leiomyoma in a 39-year-old woman that involved the soft tissues, skeletal muscles, lungs and breasts...

Leiomyoma of the lung is very rare in children. The case history is presented of an 8 year old boy with an endobronchial leiomyoma which caused total atelectasis of the left lung.

Leiomyoma of the lung is extremely rare. The entity is not described in WHO blue book. Less than 100 cases of leiomyoma of the lung have been reported in the literature. However, vascular leiomyoma has not been reported in the literature, to the author's best knowledge. Herein reported is the first case of vascular leiomyoma of the lung arising from smooth muscles of the pulmonary artery. A 62-...

Benign metastasizing leiomyoma (BML) is a rare disease that usually occurs in women of reproductive age. They typically have history of uterine leiomyoma treated with hysterectomy. BML can metastasize to distant organs, with the lung being the most common organ. We report two patients who presented with benign metastasizing leiomyoma to the lung. Our first case was a fifty-two-year-old female w...

We report a case of multiple benign metastasizing leiomyoma (BML) lung nodules showing faint or non-avid uptake of F-18 fluorodeoxyglucose (FDG) (respective 1-hour early and 2-hour delayed maximum standardized uptake values; 1.3 or less and 1.2 or less) in a 50-year-old woman with a history of hysterectomy for uterine leiomyoma at the age of 38 years. When multiple lung nodules show faint or no...

The first case of a primary leiomyoma in a pulmonary vein in an adult is presented. Although rare, leiomyoma and leiomyosarcoma of the lung and great vessels should be included in the differential diagnosis of intrathoracic space occupying lesions.

that affects women with a history of a uterine leiomyoma. However, a benign metastasizing leiomyoma without a history of previous surgery has rarely been reported. Typical radiographic findings include well-circumscribed solitary or multiple pulmonary nodules ranging from a few millimeters to several centimeters in diameter and scattered among the normal interstitium. We report a case of abenig...

BACKGROUND Intravenous leiomyomatosis is a special type of uterine leiomyoma and features formation and growth of benign leiomyoma tissue within vascular wall. Benign metastatic leiomyoma refers to benign leiomyoma metastasizing to extra-uterine sites, dominantly lung. Solitary or multiple small nodules in the lung can be seen in image scans. METHODS We report 2 cases of intravenous leiomyoma...

Pulmonary benign metastasizing leiomyoma (PBML) is defined as metastasis of a leiomyoma to lung tissue. It was first reported in 1937. P BML 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.
