Abstract

Benign metastasizing leiomyoma (BML) in the lung is a very rare metastatic disease. BML accompanied with primary lung cancer is even more uncommon. In our report, a 38-year-old female who undertook routine computed tomography (CT) scan revealed the pulmonary abnormality. Chest CT imaging showed a ground-glass opacity (GGO) nodule coexisted with a solid mass, which was prone to be diagnosed as a primary lung cancer with metastasis. However, the pathological immunohistochemical staining result proved the diagnosis of BML accompany with primary lung adenocarcinoma. Our case presented a valuable report for radiologist and clinician to identify the diagnosis and differentiated diagnosis, and understand the pathogenesis, treatment and prognosis of the tumor in further.
