8.1 Pediatric Salivary Gland Neoplasms Salivary neoplasms are uncommon in children. They may arise in the acini and ducts (epithelial tumors) or in mesenchymal tissue, e.g., the intraparotid lymphoid (lymphoma) or connective tissue (neurofibroma, schwannoma, rhabdomyosarcoma). They may be benign…
7.1 Bacterial Infection Bacterial Infections Salivary gland infections are in general not a common condition. The incidence, complications, and mortality rates of salivary gland infections have decreased largely due to improved oral hygiene and advances in health care. There remains…
Prognostic Categories of Salivary Tumors The histologic classification of salivary tumors is difficult in a significant proportion of tumors. The main reasons are that they are rare compared with tumors of other organs, and they comprise an unusual large spectrum…
Introduction The histology of salivary glands was established by the end of the 19th century, when some intracellular organelles could be demonstrated ( Fig. 5.1 ). Today, the familiar and reproducible routine histologic appearance of the salivary glands is a…
Introduction Open biopsies are contraindicated because of the risk of tumor cell seeding, which increases the risk of recurrence of both malignant neoplasms and pleomorphic adenomas. Facial nerve injury, wound infection, salivary fistula, or sialocele are reported after open biopsies;…
3.1 Conventional Plain Films Conventional X-ray imaging of the salivary gland has diminished relevance. The soft tissue X-ray does not depict a salivary stone well, and the summation effects of conventional X-ray images can make it difficult to locate the…
Introduction Salivary glands play an essential role in maintaining oral homeostasis by secreting saliva under unstimulated (resting) and stimulated (neuronal-regulated) conditions. For example, saliva functions as a barrier for bacterial infestations due to its antibacterial composition. It also plays the…
Introduction The major salivary glands: parotid, submandibular, and sublingual glands, are paired and symmetric. In the oral cavity 700–900 minor salivary glands are found, the majority of which are located at the junction of the hard and soft palates. In…
