Eisele notes that in addition to rare instances when a pleomorphic adenoma turns malignant, a cancerous parotid tumor can arise from skin cancers such as squamous cell carcinoma or melanoma that spread (metastasize) to the gland, which has lymph nodes imbedded inside. About 1.5% of the tumors become malignant in the first five years, rising to 9.5% after 15 years. The majority of patients first present to the primary care clinician or nurse practitioner with complaints of a painless lump. Treatment usually involves surgery to remove the tumor completely. Outline the types of salivary gland tumors. The predictive values were: PPV 66.8% and NPV 93.6%. Those with chronic parotitis usually don't have much pain or discomfort. The parotid glands are salivary glands that sit just in front of the ears. Part A: from aetiopathogenesis to diagnosis. Parotid gland. Biopsy; Malignancy; Mass; Parotid; Radiology. There are different types of tumors, but the most common type is pleomorphic adenoma, a slow-growing tumor. Neck dissection should be carried out in patients with clinical or radiological evidence of nodal disease. This can cause loss of movement in the face muscles. [7]The position of a tumor in the superficial or deep aspect of the parotid gland is established by the identification of its relation to the retromandibular vein.

Approximately 300 cases per year of primary salivary gland malignancy are registered in the United Kingdom, of which fewer than ten occur in children. The greater auricular nerve as a donor is an option, but it may be involved, so the sural nerve from the leg may be preferred. The following MRI parameters were evaluated: shape, site, size, margins, signal intensity (SI) on T1w and T2w images, contrast enhancement, signal of cystic content, presence or absence of a capsule, perineural spread, extraglandular growth pattern and cervical adenopathy. A few weeks delays can make a significant difference to the complexity of the planned surgery, with tumors readily invading the skin andsurrounding structures. Salivary gland cancer can be prevented by avoiding the possible risk factors namely tobacco and alcohol. Fine-needle aspiration biopsy (FNA) is the primary diagnostic tool for salivary gland lesions, but the role of FNA in the diagnosis of benign and malignant salivary gland disease still carries some controversy.
