本文对头颈部结内唾液腺组织（ISGT）的发生和组成进行了研究。ISGT主要由成熟腺泡、闰管和小叶内导管组成，但也有未成熟腺泡（20.8%）和未成熟小导管（18.8%）。后者类似于早期发育阶段的唾液腺组织。ISGT的组织学改变包括囊肿形成（16.7%）和嗜酸细胞化生（8.3%）。嗜酸细胞腺瘤样增生（8.3%）和导管增生（20.8%）。因此，ISGT可能含有具有分化和增殖潜力的不成熟成分。
The occurrence and composition of intranodal salivary gland tissue (ISGT) in the head and neck region were investigated. ISGT was mainly composed of mature acini, intercalated ducts and intralobular ducts but immature acini (20.8%) and immature small ducts (18.8%) were also observed. The latter resembled salivary gland tissue in an early developmental stage. Various histological changes of ISGT were observed including cyst formation (16.7%), oncocytic metaplasia (8.3%). oncocytic adenomatous hyperplasia (8.3%) and ductal proliferation (20.8%). Thus ISGT may contain immature components with a potential for differentiation and proliferation.
