Endobronchial sialolipoma. Case report

Abstract

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.

Endobronchial Sialolipoma: An Uncommon Salivary Gland Tumor at an Uncommon Site

“…Two cases were detected incidentally as a result of body screening for some other reasons. 7,8 The exact duration of symptoms cannot be specified; however, the minimum period documented was 3 months in our patient.…”

“…The search yielded a total of five cases in the English literature. [5][6][7][8][9] Two of these cases were documented under the heading of adenolipoma. 5,7 However, the recent WHO does not recommend the use of "adenolipoma" to highlight the benign nature of the epithelial (salivary gland) component.…”

“…In the majority, the lesion was excised completely using forceps through bronchoscopic approach. [6][7][8] Some of them underwent lobectomy surgery due to the size, location, and the obstructive mass effect on the underlying lung parenchyma. 5,9 No recurrence was noted once the growth is completely excised.…”

“…4 Due to its rarity in the endobronchial site, we searched PubMed using the terms “sialolipoma,” “lipoadenoma,” and “adenolipoma” AND “bronchus.” The search yielded a total of five cases in the English literature. 5‐9 Two of these cases were documented under the heading of adenolipoma. 5,7 However, the recent WHO does not recommend the use of “adenolipoma” to highlight the benign nature of the epithelial (salivary gland) component.…”
