[Non-neoplastic enlargement of salivary glands: clinico-histologic analysis].
We carried out a retrospective study on non-neoplastic enlargement of the salivary glands at the Oral Histopathology Diagnostic Center of the Autonomous Metropolitan University at Xochimilco (UAM-Xochimilco) in Mexico during a period of 24 years (1979-2003). From 5,625 biopsies received and analyzed, a total of 461 (8.2%) were non-neoplastic enlargement of the salivary glands; for each case, we registered demographic data as well as clinic characteristics. These lesions were characterized as a heterogeneous group of pathologic entities among which we included local, obstructive, infectious, and immunopathologic lesions. The most frequent lesion was the extravasation cyst in 341 (74%) cases, followed by chronic sialoadenitis and Sjögren's syndrome with 54 (11.7%) and 41 (8.8%) cases, respectively, and at a lesser percentage mucous retention cyst, sialosis, benign lymphoepithelial lesions and those related with sialolytes. Females were affected more frequently; mean age was second to third life decades. These lesions were most frequently localized on inferior labial mucosa.
