Mixed tumor of left parotid gland?

summary

Mixed tumor of parotid gland is more common in young adults. The tumor is located below the earlobe and extends to the neck when it is large. The tumor was nodular and sometimes cystic with soft nodules. There was no adhesion between the tumor and the skin or basal tissue, which could be pushed; The growth is slow, but it doesn't change for several years or more than ten years. In case of malignant transformation, the tumor often grows rapidly and adheres to the surrounding tissues. In the late stage of malignant transformation, the tumor may be broken, with pain or facial paralysis, and lymph node metastasis in the lateral cervical region. Mixed tumor of left parotid gland? Let's talk about it

Mixed tumor of left parotid gland?

Mixed tumor of parotid gland is more common in middle age. Generally no obvious symptoms, slow growth, course of disease up to several years or even decades. Most of the tumors presented as solid and tough masses in the infraauricular region, with nodular surface, clear boundary, moderate hardness, no adhesion to surrounding tissues, mobility and no tenderness. The possibility of malignant transformation should be considered if one of the following conditions occurs. ① The tumor grew rapidly, the mobility decreased or even fixed, and the pain or ipsilateral facial paralysis appeared.

Mixed tumor of parotid gland is composed of neoplastic epithelium and mucoid or chondroid stroma. According to the proportion of its components, it can be divided into cell rich mixed tumor of parotid gland and stroma rich mixed tumor of parotid gland. It is generally believed that the cell rich type is relatively easy to malignant transformation, and the interstitial rich type is relatively easy to relapse. Mixed tumor of parotid gland can occur at any age, most of which are 30-50 years old, and a little more common in women. Mixed tumor of parotid gland usually presents as oval or round mass with slow growth, often without conscious symptoms and long history. The mixed tumors of parotid gland are well circumscribed and of medium texture, most of which are 2-125px in diameter; Small mixed tumors of parotid gland usually form smooth and movable solid masses; The larger ones tend to bulge and affect the surface skin or mucous membrane. The palpation is nodular. The higher part is usually soft and may have cystic changes. The lower part is hard and mostly solid tissue; Multiple recurrence can form a fixed mass.

When parotid mixed tumor grows slowly for a period of time and suddenly appears growth acceleration, accompanied by pain, facial paralysis and other symptoms, malignant transformation should be considered. It is necessary to carefully observe the presence of focal malignant transformation and extracapsular infiltration in parotid mixed tumors with a diameter of more than 100px and a stage of more than 5-10 years.

matters needing attention

Although parotid mixed tumor is a kind of benign tumor, and growth is slow, but for patients, timely detection and treatment, will be of great help to their own body, not only that, active treatment at the same time to avoid the possibility of benign tumor deterioration, avoid endangering the lives of patients.
