A patient with concurrent endobronchial leiomyoma and uterine leiomyoma: A case report

Background: Benign endobronchial tumors are uncommon, accounting for 2% of all pulmonary tumors. Primary endobronchial leiomyomas are extremely rare, accounting for approximately 0.66% of all benign pulmonary tumors. Case presentation: In this report, we describean uncommon case of a female patient with concurrent endobronchial and uterine leiomyomas who underwent radial endobronchial ultrasound, electrocautery snaring, and argon plasma coagulation for bronchoscopic resection of the endobronchial lesion. Conclusions: : Primary endobronchial leiomyomas are rare and diagnosed based on the pathological results, which excluded malignant lung cancer and other spindle-cell tumors. A differential diagnosis of BML could not be ignored in this patient because of her history of uterine leiomyoma.
