Abstract

The spectrum of salivary gland lesions is wide and the relative incidence of neoplastic versus non-neoplastic lesions is variable in different studies. A series of non-neoplastic salivary gland lesions is reviewed to analyze their spectrum and their relative frequency. This is a retrospective study of salivary gland excisions and biopsies received in our department from January 1994 to December 2008. Routine hematoxylin and eosin-stained sections of all the salivary gland excisions and biopsies received were analyzed. Of the 393 salivary gland excisions and biopsies received, 216 cases were reported as non-neoplastic (55%) and formed our study group; 177 (45%) were neoplastic. Non-neoplastic lesions were more frequent in major salivary glands (65.7%) and submandibular gland was the most commonly involved (66.2%). Lip was the most frequent site (81.7%) for minor salivary gland lesions. Inflammation was the predominant pathological finding (49.5%), of which non-specific chronic sialadenitis constituted the majority (86.9%). Sialolithiasis was present in 22 cases (20.6%); all of these cases were of non-specific chronic sialadenitis. Cysts were second in frequency (36.6%), of which mucocele was the most common (54.5%). There were 5.6% cases of benign lympho-epithelial lesions, while normal salivary gland tissue was seen in 6.5% cases. Non-neoplastic salivary gland diseases are more common than neoplastic diseases and have a wide disease spectrum.
