Benign metastatic leiomyoma of the lung. A case report

Leiomioma Metastasico Benigno Pulmonar

Benign metastatic leiomyomatosis (BML) is a rare disease in which the lung is the most commonly affected extrauterine organ. We present a brief review of the literature, along with a case report of a patient who underwent surgical treatment at the pulmonary level resection of the lung lesion with subsequent pathologic confirmation by biopsy. The clinical course of benign metastatic leiomyomatosis varies from chronic asymptomatic onset to rapid progression leading to respiratory failure and death. Our patient presented with pulmonary symptoms such as cough, dyspnea or chest tightness, with diagnostic image of simple and contrasted thoracic CT scan showing pleural effusion, a surgical procedure was performed by thoracoscopy with evidence of tumor-like lesion with cystic component. Pleurectomy + decortication was performed and it was decided to perform a non-anatomic segmental pulmonary lobectomy. The pathological anatomy revealed benign leiomyomas without atypia and mitotic activity, patient has not yet established a standard treatment for benign metastatic leiomyomatosis, due to the hormone sensitive characteristics of the LBM, currently in multidisciplinary follow-up. treatments are based on hormonal manipulation along with surgical or medical oophorectomy
