It’s important to note that each structure is linked to a network of ducts that carry saliva into the oral cavity. While in each of these structures neoplasm or tumor growth is possible, the parotid gland is the most common source of salivary gland tumor. In the parotid gland, more than 80% of all salivary gland tumor occur. Parotid gland tumor could be divided into two main behavioural, benign and malignant categories. Benign tumours usually are the product of several aberrant intracellular events and are non-aggressive cell growths. Typically, these tumours grow slowly over time, are not painless and do not invade or destroy neighbouring tissues. However, benign parotid tumor can compress adjacent structures and cause dysfunction of surrounding structures based purely on the effects of their occupying space.
Although the word benign carries better connotations than more aggressive tumours, it is important to note that, unless treated promptly; benign parotid tumours can undergo a malignant transformation over time.Malignant transformation alters prognosis and significantly impacts treatment protocols. Malignant tumours may display more aggressive patterns of growth, as well as invade adjacent tissues. Parotid tumours can differ in appearance and the symptoms associated with them. Because of a variety of factors including tumour type, location, the extent of disease, comorbidities, and general patient health, each case of the parotid tumor must be carefully evaluated for accurate diagnosis and an appropriate treatment plan must be tailored to suit. A specialist in salivary glands is aware of these sensitive factors and is most qualified to assess and treat suspected cases of parotid tumor.
