Misdiagnosed Asthma Turned Out to Be Bronchial Fibroepithelial Polyp: Case Report and Review of Literature

Bronchial fibroepithelial polyps are exceedingly rare with few cases have been reported. They can manifest with a wide array of symptoms; ranging from being totally asymptomatic, cough, refractory dyspnea, and hemoptysis. In our case, our patient's condition was diagnosed and was managed as asthma. It is one of the rare benign conditions to be encountered, shares similar morphology with other tumors such as angiomyofibroblastoma, aggressive angiomyxoma, and cellular angiofibroma. These lesions have a slow growth pattern which may end up with obstruction. According to the tumor size and symptoms caused by it, treatment varies from observation to complete resection. This case describes an incidental finding of fibroepithelial polyp in the main bronchus for a patient with long-term refractory cough for 5 years, was misdiagnosed to have asthma. Diagnosis typically involves imaging and bronchoscopy, followed by appropriate therapeutic measures and careful monitoring to assess the prognosis.

Bronchial Fibroepithelial Polyp With Severe Hemoptysis as First Manifestation: A Case Report

Fibroepithelial polyps are uncommon benign tumors that mostly occur in skin, oral cavity and genitourinary tract. These lesions have common morphological features with other mesenchymal tumors such as angiomyofibroblastoma, aggressive angiomyxoma, and cellular angiofibroma and present with numerous histological appearances. Benign endobronchial tumors are rare. These neoplasms have a slow growth and usually are related to bronchial obstruction. Only a few cases of bronchial fibroepithelial polyps have been reported. Bronchial fibroepithelial polyps might present with airway stenosis resulting in atelectasis and bronchiectasis and the most frequent manifestations are recurrent infection, refractory asthma, dyspnea and hemoptysis. Chronic inflammation is associated with the pathogenesis of fibroepithelial polyps. Treatment varies according to mainly to the size and symptoms. Small lesions presenting with few symptoms can be treated with corticosteroids and antibiotics while invasive techniques including bronchoscopic resection of the polyp or lobectomy are used for larger lesions. We report a case of a bronchial fibroepithelial polyp with severe hemoptysis as the first manifestation. Physicians should always suspect these lesions in the differential diagnosis of hemoptysis and with initial right diagnosis surgical procedures can be avoided.

A bronchial fibroepithelial polyp with abnormal findings on auto-fluorescence imaging

Bronchial fibroepithelial polyps represent a rare type of tumour that displays endobronchial growth. The findings of these lesions on auto‐fluorescence imaging (AFI) bronchoscopy have not been reported, despite the usefulness of AFI in detecting early lung cancer. We report the case of a patient with a bronchial fibroepithelial polyp that displayed positivity (magenta colour) on AFI. The patient was a 65‐year‐old man, in whom an endobronchial polypoid lesion of 10 mm diameter had been detected in the right basal bronchus by chest computed tomography (CT). On bronchoscopic examination, we found a whitish, smooth polypoid lesion. The lesion appeared magenta on AFI. On CT, however, the lesion had been almost stable for 4 years and 4 months. Bronchial fibroepithelial polyps may show AFI positivity, even when the lesion displays benign behaviour. The diagnosis of the lesion should not be confused by AFI positivity, and unnecessary surgical intervention should be avoided.
