Inflammatory Endotracheal Polyp Resolved after Antibiotic Treatment

Abstract

We describe a rare case of asymptomatic inflammatory endotracheal polyp resolved by antibiotic treatment. Histological examination of biopsy specimens showed an inflammatory polyp consisting of fibrovascular stroma and sparse lymphocyte infiltration. The size of the polyp was unchanged during 3 months without any treatment and its etiology was unclear. Although a bacterial organism was never proven, the polyp decreased remarkably under treatment with an oral antibiotic (ciprofloxacin) and did not recur for 6 months. Antibiotic treatment may be of value for inflammatory tracheobronchial polyps in cases of unclear etiology.

Bronchial Fibroepithelial Polyp: A Case Report and Review of the Literature

“…Several chronic inflammatory etiologic factors, such as chronic smoke inhalation, chronic inflammation in patients with asthma and chronic obstructive pulmonary disease (COPD), repeated airway infections, foreign body aspiration and prolonged mechanical ventilation may be potential causes. Yamagishi et al described a case of polyps that were resolved with antibiotic treatment (14). Consequently, our patient was treated with low-dose glucocorticoids and azithromycin for three months.…”

Tracheal obstruction by an eosinophilic polyp in a horse

“…Tracheobronchial inflammatory polyps in man have been classified into 3 categories: 1) benign inflammatory polyps; 2) multiple papillomatosis; and 3) solitary papillomas. The latter 2 categories have malignant potential (Yamagishi et al 1993). The polyp described in this report would be classified in the first category.…”

“…Still, there has been no guideline or randomized controlled trial regarding the treatment of inflammatory polyp, but some previous cases have reported reduction in the size after use of antibiotics, steroids, and intervention . Antibiotics and steroids were used in our cases as we assumed EBUS‐TBNA might have caused mucosal disruption with infection which resulted in inflammatory process.…”
