Endobronchial Hamartoma - A Case Report

Endobronchial hamartochondromas, benign tumors originating from peribronchial mesenchymal tissue, are exceptionally rare, comprising only 1.4% of pulmonary hamartomas. We present a clinical case involving a patient with symptomatic hamartochondroma, presenting with cough and thoracic pain. Thoracic computed tomography revealed middle lobe atelectasis associated with an endobronchial protrusion, while bronchoscopy demonstrated a tumor arising from the middle lobar bronchus, extending into the right intermediate bronchus. Despite inconclusive findings from bronchial biopsy histopathology, a multidisciplinary consensus led to surgical intervention, confirming the diagnosis through anatomopathological examination. In conclusion, prompt resection, whether surgical or endoscopic, is imperative to mitigate bronchial obstruction complications and prevent the misidentification of malignant lesions.
