The Natural Course of Endobronchial Inflammatory Polyps as a Complication after Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration

Successful excision of an inflammatory endobronchial polyp using biopsy forceps with improvement in FEV1 in a patient with allergic bronchopulmonary aspergillosis: A case report

Inflammatory endobronchial polyps (IEPs) are rare, benign bronchial tumors posing diagnostic and therapeutic challenges owing to limited data. A 55-year-old man, receiving treatment for allergic bronchopulmonary aspergillosis, presented with a one-week history of fever and purulent sputum. Diagnosed with pneumonia, he received antimicrobial treatment. However, because of persistent symptoms, an endobronchial tumor was suspected on computed tomography. IEP was confirmed through flexible bronchoscopy with forceps biopsy, and polyp removal improved symptoms, lung function, and imaging.

Benign Endobronchial Inflammatory Polyp with Cystic Degeneration: A Case Report

Endobronchial lesions causing luminal obstruction are mostly found in bronchogenic carcinoma. Inflammatory polyps originating from the tracheobronchial tree are rarely found. Here we report a case of an elderly male presenting with prolonged cough who was found to have an endobronchial inflammatory polyp. The polyp was resected completely with the use of the flexible bronchoscope and electrocautery snare.

Tracheobronchial puncture-site nodular reaction (TPNR) following endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA): Systematic review of case reports

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive and efficacious diagnostic modality for lung cancer staging and evaluation of undiagnosed mediastinal lymphadenopathy. Procedure-related complications are uncommon. We herein report an infrequently described phenomenon following EBUS-TBNA in which two patients developed nodular granulation tissue at the tracheobronchial puncture site. On systematic review, we found description of such phenomena by terminologies such as endobronchial inflammatory polyp, granuloma, and endobronchial mass. The endobronchial inflammatory polyp has been one of the most commonly used terminologies for these; but in most cases, the classical features of an inflammatory polyp are lacking. We propose the term, tracheobronchial puncture-site nodular reaction (TPNR) with further classification into granulomatous and nongranulomatous subtypes, for standardized reporting of such reactions following transbronchial needle aspiration procedures. Knowledge of this entity and standardized nomenclature shall help in better characterization of the outcomes and risk factors for the occurrence of these reactions.
