Pleomorphic adenoma is the most common salivary gland tumor is benign and is composed of epithelial cells in a tissue or a chondroid or myxomatous matrix Chondroid. The "pleomorphic" concept refers to the wide variety of structures may appear in.
Symptoms of benign tumors in the salivary glands
When found in the parotid gland (under the ear and behind the lower jaw) and lift and separate the pinna, distending the skin, the tumor can sometimes cause pain by compression in the facial nerve.
But if it originates from an accessory gland (salivary gland), growth causes increased volume of the area, but rarely causes pain by nerve compression.
Typically, this tumor chewing difficult and, in some cases, the patient claims to have difficulty speaking.
Characteristics of benign tumors in the salivary glands
Pleomorphic adenoma is usually a single tumor, grayish-white, with well-defined limits, encapsulated, firm and usually multilobulated. The outer surface is smooth, although in some cases may be roughened.
When the tumor affects intraoral accessory gland, the size usually does not exceed 1 or 2 cm in diameter, although in some cases can be up to 6 or 7 cm.
The mouthparts most affected by this tumor are lip and palate, as 85% of these tumors are found in the parotid glands, compared with 8% in the submandibular and 7% in minor glands.
Since there are no signs that the tumor be a pleomorphic adenoma or other salivary tumor, you need to go to a consultation of Dentistry to explore, analyze its composition and diagnosis.
