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.
对头颈部区域的结内涎腺组织（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，但也观察到未成熟腺泡（20.8%）和未成熟小导管（18.8%）。后者类似于发育早期的涎腺组织。观察到ISGT的各种组织学变化，包括囊肿形成（16.7%）、嗜酸性化生（8.3%）、嗜酸性腺瘤样增生（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未成熟成分。
