Objectives: To compare the ultrasonographic (US) appearances of the oral mu
cosa in health with patients with systemic sclerosis (SSc).
Methods: An innovative 20 MHz US scanner was used to examine the lips, chee
ks and oral vestibule of ten healthy persons and ten patients with SSc. The
clinical, US and histopathological features of one patient with a fibro-ep
ithelial polyp of the buccal mucosa are reported in detail.
Results: Two patients with SSc displayed increased echogenicity due to fibr
otic deposits. A similiar echo pattern was seen in the case of the histopat
hologically verified fibro-epithelial polyp of the buccal mucosa.
Conclusion: 20 MHz sonography may be suitable as a non-invasive tool for ev
aluation of fibrosis of the oral mucosa.
