Quantification of nerve density in neurofilament-stained biopsy specimens of a salivary gland group, consisting of the high-PNI malignancies, ACC and PLGA, compared with the low-PNI malignancy, LG MEC, and normal/ reactive gland (mucocele) and an epithelial group, composed of HNSCC compared with BCC and normal/reactive mucosa (acanthosis).
LG, low grade.
