A small tumor grows inside the neck

The neck is a very important part of the human body and is very sensitive. It is also a place where lesions can easily occur. If there is a small tumor growing inside the neck, it is most likely a lipoma. Because a single morphology cannot lead to an accurate conclusion, you need to have a further understanding of the lipoma and make a judgment based on your own physical condition. Now let's look at the situation of lipoma.

Causes

The cause of lipoma is not yet fully understood. It may be related to factors such as inflammatory stimulation of connective tissue degeneration, abnormal and disordered adipose tissue metabolism, abnormal secretion of anterior pituitary gonadal hormone levels, congenital dysplasia, and intestinal malnutrition. About 1/3 of patients with multiple lipomas may have a family history.

There is a "lipoma tumorigenic factor" in the human body. Under normal circumstances, this tumorigenic factor is in an inactivated state (inactive state) and will not cause disease under normal circumstances. However, under the influence of various internal and external environmental factors, this lipoma tumorigenic factor is in an active state and has a certain activity. When the body's resistance decreases, the body's lymphocytes, mononuclear macrophages and other immune cells' ability to monitor the tumorigenic factor decreases. Coupled with changes in the body's internal environment, chronic inflammatory stimulation, abnormal systemic fat metabolism and other inducing conditions, the activity of the lipoma tumorigenic factor is further enhanced and combined with certain gene fragments in the body's normal cells to form abnormal gene mutations, causing an abnormal proliferation of normal fat cells and surrounding tissue cells, leading to the deposition of adipose tissue and the formation of lumps protruding from the body surface or various internal organs, namely lipomas.

Clinical manifestations

Superficial lipomas cause few symptoms other than a localized lump. It can be single or multiple, and the size can range from a few millimeters to tens of centimeters. The tumor grows slowly, has a soft texture, clear boundaries, is lobed, has good mobility when pushed, and can cause skin depression when moved. It rarely causes pain, and pain that does occur is often a late symptom caused by large lipomas compressing peripheral nerves.

Deep or subfascial lipomas can cause a variety of symptoms, depending on their location and size. If a lipoma is operated on, it may cause a feeling of stagnation or limitation of movement. Larger mediastinal lipomas may cause dyspnea or palpitations.

Lipomas are common in obese people, and their size increases when weight increases rapidly, but on the contrary, lipomas do not shrink when weight decreases severely.

treat

Isolated lipomas less than 1 cm in diameter generally do not require treatment. Larger ones can be removed surgically. Deep lipomas are sometimes difficult to completely remove and may recur locally, but rarely become malignant. The treatment of multiple lipomas is also mainly local excision.
