Endobronchial sialolipoma. Case report.

Background: A 52-year-old woman presented with shortness of breath and cough. An endobronchial sialolipoma was found at the left entrance of the main bronchus. Sialolipoma is an exceedingly rare type of lipoma reported of the minor salivary glands, especially within the bronchus.

Case Presentation: A 52-year-old woman presented with shortness of breath and cough with 6 months´ evolution. Endobronchial endoscopy revealed a tumour at the left entrance of the main bronchus. The entire removal of the tumour was removed using a cryoprobe device. Pathological examination showed a tumour consistent with the diagnosis of sialolipoma due to the presence of mature adipose cells blended with acinar, ductal, basal, and myoepithelial cells. The patient had a favourable outcome.

Conclusion: The infrequent tracheobronchial presentation of this tumour can be challenging for correct diagnosis.
