What is the reason for a hard pimple on the skin?

We must pay special attention to our physical health in daily life. If you find hard lumps on your skin, you should pay attention to whether they are lipomas. Although lipomas are benign tumors that often occur under the skin, they can also have adverse effects on our health.

1. It may be a lipoma. Lipoma is a benign tumor that mostly occurs under the skin. There is a thin connective tissue capsule around the tumor, which contains normal fat cells divided into leaf-like groups by connective tissue bundles. Some lipomas contain a lot of connective tissue or blood vessels in addition to a large amount of adipose tissue, forming a complex lipoma. .

3. This type of tumor often occurs on the shoulders, back, buttocks and inner thighs, and is also common on the head. Lipomas located in the subcutaneous tissue vary in size, most of which are oblate or lobed with clear boundaries. If the boundaries are unclear, beware of the possibility of malignant lipomas. The tumor is soft and elastic (note the difference from larger cysts), and some may have a false sense of fluctuation. The tumor is not adhered to the epidermis, the skin surface is completely normal, and the base is relatively wide. During the examination, if you press the base of the lipoma tightly with your hand, you can see the lobed shape. The skin may appear "orange peel". Tumors develop very slowly, most of them have no serious adverse effects on the body, and very few of them become malignant.

In addition, there is another type of multiple round or oval nodular lipomas, which are commonly found subcutaneously on the limbs, waist, and abdomen. The size and number of the tumor are uncertain. It is slightly harder than ordinary lipomas and painful when pressed, so it is called painful lipoma or multiple lipomas.

4. Smaller lipomas that develop slowly and have no clinical symptoms generally do not require treatment. There are many ways to treat lipomas with laser surgery, but for small lipomas, micro-incision laser excision and lobular removal are used. Larger lipomas are removed through incision selected according to their location and surgical requirements. Laser removal of lipomas is extremely convenient.
