Table 1 Clinical and pathologic characteristics of the 13 included lesions

From: HMGA2 immunostaining is a straightforward technique which helps to distinguish pulmonary fat-forming lesions from normal adipose tissue in small biopsies: a retrospective observational study about a series of 13 lung biopsies

Case Sex Age (years) Presentation Location HMGA2 staining Remark
1 M 61 Smooth endobronchial lesion. Right upper lobe POSITIVE  
2 M 65 ENT carcinoma. Hemoptysis. Suspicious endobronchial lesion. Right upper lobe POSITIVE  
3 M 50 Hemoptysis. Small sessile endobronchial lesion. Left lower lobe POSITIVE  
4 M 55 COPD and obesity. Acute pulmonary insufficiency. Non suspicious endobronchial lesion. Right lower lobe NEGATIVE Superficial epithelial cells were stained.
5 M 55 COPD and obesity. Acute pulmonary insufficiency. Non suspicious endobronchial lesion. Left upper lobe NEGATIVE Superficial epithelial cells were stained.
6 M 58 Small cell neuroendocrine carcinoma. Endoscopic evaluation after 6 courses of chemotherapy. Left lower lobe NEGATIVE  
7 M 64 Squamous cell carcinoma of the left upper lobe. Lipomatous endobronchial lesion. Middle lobe POSITIVE Superficial epithelial cells were stained.
8 F 44 Ankylosing spondylarthritis. Dyspnea. Small non suspicious endobronchial lesion. Trachea NEGATIVE Superficial epithelial cells were stained.
9 F 77 Smooth pediculated endobronchial lesion. Fat density on imaging. Left lower lobe NEGATIVE Superficial epithelial cells were stained.
10 M 43 Endobronchial lesion. Left upper lobe POSITIVE  
11 M 77 Pediculated endobronchial lesion causing complete bronchial obstruction. Calcification on imaging. Adipose lesion macroscopically. Right upper lobe POSITIVE  
12 F 9 Localized bronchiectasis. Round whitish lesion causing complete bronchial obstruction. Left lower lobe NEGATIVE  
13 M 76 Incidental. Endoscopy for exposure to asbestos. Smooth endotracheal lesion with yellowish area macroscopically. Trachea POSITIVE
