Answer

Salivary gland biopsy can also help to detect pseudolymphoma or lymphoma, as well as the noncaseating granulomas of sarcoidosis.

One study showed that not all patients undergoing lip biopsy derived diagnostic benefit from this procedure and that clinical symptoms and serology did not predict a positive lip biopsy. [72]

In another study, however, a significant correlation was found between positive findings in minor salivary gland biopsy and the Schirmer test, the rose bengal test, xerostomia, and parotid swelling. The investigators utilized biopsy specimens from the lower lip of 360 patients. [73]
