涎腺始基瘤非常罕见,目前在国内文献中尚未见报道。该瘤患者绝大多数为出生后数天至6周的婴幼儿,并明显以男婴多见。患儿在临床上常表现为呼吸窘迫、缺氧及进食困难等。肿瘤常以细蒂附着于鼻咽部的中线部位,瘤体很容易脱落。镜下肿瘤表面被覆无角化的复层鳞状上皮,鳞状上皮向深部间质内延伸,形成分支的网状、条索状及腺样结构。在肿瘤内瘤细胞常呈梭形,细胞形态温和,很少有核分裂象。肿瘤为良性,切除后不复发。而在手术过程中务必保持警惕,严防因肿瘤脱落而导致患儿呼吸道阻塞及窒息。 Salivary primary tumor is very rare, at present, no reports in the domestic literature. The vast majority of patients with the tumor is a few days to 6 weeks after birth, infants and young children, and obviously more common in boys. Children often manifest in clinical respiratory distress, hypoxia and eating difficulties. The tumor is often attached to the central part of the nasopharynx with fine pedicle, the tumor is easy to fall off. Microscopic tumor surface covered hornless stratified squamous epithelium, squamous epithelium extending to the deep mesenchyma, forming a network of branches, cords and adenoids like structure. In tumor tumor cells are often fusiform, cell morphology is mild, rarely mitotic. The tumor is benign and does not recur after resection. In the course of surgery must be vigilant to prevent the tumor due to the loss of airway obstruction and suffocation.
