Wang Y, Zhang Y, Tong R. Case report: Successful bronchoscopic interventional treatment of endobronchial leiomyomas. Open Life Sci 2024; 19:20220845. [PMID: 38737105 PMCID: PMC11087738 DOI: 10.1515/biol-2022-0845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 12/04/2023] [Accepted: 02/28/2024] [Indexed: 05/14/2024] Open
Abstract
Endobronchial leiomyomas are rare benign neoplasms of the lungs that arise from the smooth muscle cells of the bronchi and bronchioles. While surgical resection is the mainstay of treatment for these tumors, bronchoscopic interventional therapies are also effective and can help preserve lung function in certain cases. A 40-year-old male patient presented with a persistent cough and sputum production for over 4 months. A chest computed tomography scan revealed nodular lesions in the lower lobe bronchus, later confirmed as an endobronchial leiomyoma. The patient refused surgical intervention and opted for minimally invasive bronchoscopic treatments, including electric snare resection, argon plasma coagulation, and balloon dilation, resulting in a successful outcome with no recurrence during follow-up. Clinicians should consider bronchoscopic interventions as a viable treatment option for endobronchial leiomyomas patients who are either ineligible for surgical resection or opt not to undergo surgery.

Abstract
Pulmonary hamartomas (PH) are rare but are the most common benign tumors found in the lungs. They are slow-growing and are usually found incidentally on chest imaging during the sixth decade of life. Approximately 10% of pulmonary hamartomas are endobronchial. Rarely, pulmonary hamartomas can cause a spectrum of pulmonary symptoms depending on their size and location. We present a case of endobronchial hamartoma causing airway obstruction and recurrent post-obstructive pneumonia.

Abstract
Inflammatory endobronchial polyps (IEPs) are rare benign lesions that originate from the bronchial mucosa. While pneumothorax is a well-known complication of various pulmonary conditions, its association with IEPs is exceedingly uncommon and poorly understood. This case report presents a unique and explosive encounter of a patient with an inflammatory endobronchial polyp who experienced a pneumothorax, shedding light on the clinical presentation, diagnostic challenges, and management strategies for this rare entity.

Abstract
Endobronchial leiomyomas are uncommon benign tracheobronchial tumors. Bronchoscopic intervention is a safe and effective strategy for patients with contraindications for surgery or refusal to undergo surgery. Endoscopic submucosal dissection (ESD) is widely used to treat early gastrointestinal tumors. The novel hybrid knife is useful during ESD owing to functions of submucosal injections, lesion dissection and hemostasis, and makes ESD more convenient. Here, we report a case of a benign leiomyoma at the orifice of RB7 in an adolescent boy. The diagnosis was confirmed based on bronchoscopic and pathological findings. The patient was successfully treated with combined electrocautery snare and cryoresection, ESD using a hybrid knife and the wound was managed with argon plasma coagulation. The postoperative course was satisfactory, with a good general condition and no severe respiratory symptoms. This is, to our knowledge, the first reported case of ESD using a hybrid knife to treat an endobronchial leiomyoma in an adolescent patient.

Abstract
Various pulmonary diseases, both benign as well as malignant, manifest in the form of endobronchial lesions on bronchoscopy. Malignancy is frequently the provisional diagnosis in the mind of a chest physician undergoing an endobronchial biopsy. Other benign diseases, however, may present similarly on bronchoscopy and computerized tomography (CT) scan. This observational study was conducted to better understand why there is such a wide range of endobronchial lesions with even more diverse radiological and pathological presentations. The research was carried out at the Department of Respiratory Medicine, Himalayan Institute of Medical Science (HIMS), Swami Ram Nagar, Dehradun. Subjects were recruited from HIMS, Dehradun patients over a 12-month period (August 2020 to July 2021). The study included patients (over the age of 18) who had a fibreoptic bronchoscopy and were found to have an endobronchial lesion. After a thorough history, examination, and application of the inclusion and exclusion criteria. 120 patients were enrolled. The majority of patients were between the ages of 56 and 65, with males outnumbering females. The majority of the patients were smokers, and the most common complaint was shortness of breath. Poorly differentiated carcinoma and squamous cell carcinoma were the most common endobronchial lesions in men, while small cell carcinoma was the most common in women. A mass lesion was the most common radiological finding, followed by mediastinal lymphadenopathy, and an exophytic lesion was the most common endobronchial lesion detected in bronchoscopy. We looked at the diseases that cause endobronchial lesions and their clinico-radiological and histopathological profiles. This study clearly demonstrates the importance of studying the histopathological profiles of patients with endobronchial growth, which can mimic malignancy in rare cases.
