Description
Summary:Background Sialolipoma is a benign neoplasm composed of neoplastic adipose tissue and normal salivary gland parenchyma. It is commonly seen in the parotid gland. The occurrence of sialolipoma in the main bronchus is exceedingly rare. Case report A 52-year-old diabetic and hypertensive gentleman presented with shortness of breath and cough for the last 3-4 months. Computed tomography bronchial angiography showed a soft tissue lesion in the right intermediate bronchus causing its complete obliteration and subsequent collapse of the right lower lobe. A rigid tracheobronchoscope revealed a polypoidal growth originating in the right intermediate bronchus. Histopathology revealed a sialolipoma. The patient was doing well on follow-up and no recurrence was noted to date. Conclusion The bronchus as the primary site for sialolipoma is unusual and has to be kept in the differential while dealing with the slow-growing endobronchial tumor.
