How about metastatic lymph nodes of salivary gland cancer?

summary

Salivary gland cancer is a malignant tumor arising from salivary gland epithelial tissue. It can originate from large salivary gland, parotid gland, submandibular gland and sublingual gland, and also from small salivary gland (mostly seen in palatal gland), that is, it can occur in any part with salivary gland. Pathological classification included mucoepidermoid carcinoma, papillary cystadenocarcinoma, acinar cell carcinoma, adenoid cystic carcinoma, adenocarcinoma, squamous carcinoma and undifferentiated carcinoma.

How about metastatic lymph nodes of salivary gland cancer?

The cause of salivary gland cancer has not been fully understood, but it is believed that most of the occurrence of salivary gland cancer is related to environmental factors, such as heat, chronic injury, ultraviolet, X-ray and other radioactive substances can be carcinogenic factors. In addition, neuropsychiatric factors, endocrine factors, immune status and genetic factors have been found to be related to the occurrence of salivary gland cancer.

Almost all of the patients were diagnosed with masses under or in front of the ear. The growth rate varies with the pathological types of the tumors. It can be accompanied by local pain, skin invasion, facial nerve paralysis, a few patients with tumor can also invade the mandibular ramus, mastoid process and middle ear cavity, and a few tumors can invade the intracranial, infratemporal fossa and parapharyngeal space. Cervical lymph node metastasis is the main cause of parotid carcinoma.

Adenoid cystic carcinoma was the most common, followed by adenocarcinoma and malignant mixed tumor, and other epidermoid carcinoma and adenocarcinoma. The clinical symptoms are related to the site of occurrence. The palate is a multiple site, which can be accompanied by pain, fixed mass, complete surface mucosa, and can invade the hard or soft palate, gingiva, alveolar bone, and even the skull base.

matters needing attention

Salivary gland cancer can be distinguished from oral fibroma, gingivoma, parotid gland mesenchymal tissue tumor, parotid lymphadenitis, salivary gland tuberculosis, lip keratoacanthoma, tongue tuberculous ulcer, lichen planus, recurrent aphthous ulcer, papilloma and eosinophilic lymphogranuloma.
