Pleomorphic adenoma most common in the parotid gland

It is the most common benign tumour affecting the salivary glands and accounts for 40-70% of all tumours of the salivary glands. It is the most common occurring tumour of the parotid gland, usually occurring in the tail of the parotid and it accounts for 80%-90% of tumours of the parotid gland. Most tumours arise in the superficial lobe. It commonly presents as a slow growing, single, painless, firm, nodular mass. Mostly asymptomatic and initially noticed or felt as a swelling in front of the ear extending to the cheek. It can be confused with other salivary gland tumours such as Warthins tumour, lymphadenopathy and Lymphoma. Benign tumours of the superficial lobe of the parotid gland are treated by surgery: superficial parotidectomy, if the deep lobe is involved then total parotidectomy is done. Although benign it has the potential to turn malignant and the incidence of malignant transformation increases with the duration of the tumour.
