and (4) performance of either FISH or p63/p40 immunohistochemistry is expected to be able to confirm the diagnosis of ACC or PLGA in small intraoral biopsies, since both techniques appeared to be diagnostically accurate in this pilot study..     ///    Our aim was to investigate the incidence of (1) MYB rearrangement and (2) p63/p40 immunoreactivity in ACC and PLGA of minor salivary glands (MSGs).     ///    Clinical utility of myb rearrangement detection and p63/p40 immunophenotyping in the diagnosis of adenoid cystic carcinoma of minor salivary glands: a pilot study..     ///    (3) combined p63/p40 immunostaining can be used to differentiate ACC from PLGA in incisionally biopsied specimens.
