Leiomyomas are rare benign tumors of the lung. They arise from the smooth muscle cells of the bronchial wall and the interstitium or from the smooth muscles of the arterioles. Symptoms are chiefly based on the degree to which bronchial obstruction occurs. Bronchoscopic intervention or lung sparing surgical resection are the treatments of choice. In leiomyomas that are accessible by bronchoscopy and confined to airway, bronchoscopic resection appears to be safe and effective. This case is being reported because of the rarity of this condition and the need to recognise the role for endobronchial intervention, thereby, avoiding major surgical procedures with the attendant risk of morbidity due to surgery.

Introduction | |  |
Leiomyomas are rare benign tumors of the lung. Symptoms are chiefly based on the degree to which bronchial obstruction occurs. Bronchoscopic intervention or lung sparing surgical resection is the treatment of choice. Here, we present a case of endobronchial leiomyoma treated with Bronchoscopic snaring.
Case Report | |  |
A 59-year-old man presented to the outpatient department with a history of cough with mucoid expectoration for the past 2 months with no other complaints.
He was a nonsmoker with a past history of anti-tubercular treatment for pulmonary tuberculosis 20 years back and on regular treatment for diabetes and hypertension.
On physical examination, he was moderately built, afebrile, and maintained optimal saturation with room air and his chest was clear on auscultation.

Radiology
CT chest axial view [Figure 2] and [Figure 3] and coronal view [Figure 4] and [Figure 5] shows intraluminal lesion in the right intermediate bronchus with the segmental collapse of the right lower lobe. | Figure 2: Computed tomography chest axial view showing intraluminal lesion in Right intermediate bronchus (RIB)

Bronchoscopy
Bronchoscopy showed polyploid lesion in the right intermediate bronchus occluding the right middle lobe and right lower lobe [Figure 6]. Bronchial wash, bronchial brush, and bronchial biopsy were taken. Bronchial wash was sent for Gene Xpert Mycobacterium tuberculosis, cytology, routine culture and sensitivity, acid-fast bacilli culture and sensitivity, and fungal culture and sensitivity. | Figure 6: Bronchoscopy image showing polyploid lesion in Right intermediate bronchus (RIB)

Biopsy histopathological examination [Figure 7] revealed some nodular foci of smooth muscle composed of elongated spindle-shaped cells with oval-to-elongated nuclei, suggestive of endobronchial leiomyoma. | Figure 7: Histopathological examination showing smooth muscle composed of elongated spindle-shaped cells with oval-to-elongated nuclei

Management
Various treatment options were discussed, and cardiothoracic vascular surgeon's opinion was obtained. It was decided to explore bronchoscopic removal in the first place and if not successful, then proceed with surgical removal. Bronchoscopy was done under general anesthesia and the pedunculated mass [Figure 8] was snared at the base and removed using bronchoscopy basket [Figure 9] and was sent for HPE. The tiny base was fulgurated using diathermy knife. Repeat HPE again confirmed the initial diagnosis of endobronchial leiomyoma.
Discussion
Leiomyomas are rare benign tumors of the lung accounting for 2% of all benign lung tumors.[1]
Bronchial leiomyomas are benign tumors which predominantly occur in the fourth decade of life with female preponderance. Bronchial leiomyomas are thought to arise from the smooth muscle cells of the bronchial wall and the interstitium or from the smooth muscles of the arterioles. Leiomyomas of the respiratory tract can be termed according to the site of occurrence, for example., tracheal, bronchial, and parenchyma based on the anatomical site of occurrence.[2]
Symptoms due to endobronchial leiomyomas are chiefly based on the degree to which bronchial obstruction occurs. The most common symptom is cough, followed by hemoptysis and wheeze.[3] Large endoluminal or compressing lesions may present with hemoptysis, atelectasis, consolidation, bronchiectasis, or postobstructive pneumonia. Pneumothorax resulting from air trapped behind an endobronchial leiomyoma has been reported.[1]
Bronchoscopic intervention or lung-sparing surgical resection is the treatment of choice. In leiomyomas that are accessible by bronchoscopy and confined to the airway, bronchoscopic resection appears to be safe and effective. This could also include debulking with thermal means including electrocautery, argon plasma coagulation, Nd: YAG laser, and cryotherapy probe.[4]
This case is being reported because of the rarity of this condition and the need to recognize the role for endobronchial intervention, thereby, avoiding major surgical procedures with the attendant risk of morbidity due to surgery.
