Endobronchial Hamartoma with Postobstructive Pneumonia- A Case of Successful Treatment with Endobronchial Interventions

Airway hamartomas are of mesenchymal tissue origin and have predominance of adipose tissue. Hamartoma refers to a tumour-like structure within an organ composed of an abnormal arrangement of tissue components normally found in that organ. The pulmonary parenchyma and airways are commonly described sites for this lesion, although endobronchial location is far less common than its parenchymal counterpart. When present within a major airway, the usual symptoms of an airway lesion like cough, wheezing, stridor, haemoptysis and postobstructive consolidation ensue. We describe the case of a 60-year-old gentleman who presented with cough of 9 months duration. On evaluation he was found to have an endobronchial lesion in the right main bronchus. The histopathology revealed features of endobronchial hamartoma which was then subjected to endobronchial intervention with electrocautery and cryoablation achieving complete removal and restoration of luminal patency. This case underscores the ability of endobronchial treatment modalities to successfully treat benign airway lesions like hamartoma when undertaken in experienced centres.
