| Research Abstract |
Various kinds of non-tumorous salivary gland lesion were collected, and each lesion was pathologically analized (definition, epidemiology, clinical features, laboratory feature, pathogenesis, histopathology, etc, ). Non-tumorous salivary gland lesions were classified and systematized as follows :
1 Developmental anomalies (aplasia, abnormal localization, duct anomaly1 etc.)
2 Degeneratiove changes, atrophy and metaplasia
(1)atrophy (2) degeneration (3) metaplasia (sebaceous cell -, mucous cell -, oncocytic -, squamous -)
3 Parenchymal hyperplasia
oncocytic hyperplasia, adenomatous hyperplasia of minor salivary gland, hyperplasia of extraglandular salivary duct epithelium
4 Sialadenosis
5 Secretory abnormalities (suppl. cystic fibrosis)
6 Sialolithiasis
7 Mucous cyst (suppl. superficial mucocele, plunging ranula)
8 Endocrine function of salivary gland
9 Sialadenitis
(1)acute and chronic sialadenitis (suppl. sialodochitis fibrinosa)
(2)infectious granulomatous sialadenitis(tuberculosis, syphilis, etc.)
(3)viral sialadenitis (mumpus, cytomegalic inclusion disease, etc.)
(4)sialadenitis in immune diseases
Sjogren syndrome (suppl. Mikulicz disease and sydrome, benign lymphoepithelial lesion, etc)
human immunodeficiency virus infection
graft-versus-host disease, others
