What causes skin fibroma and what are the symptoms?

Dermatofibroma is usually a skin proliferative lesion caused by trauma, inflammatory response or genetic factors. Its symptoms are local round, hard nodules, mostly brown or yellow, painless and itchy. It is necessary to choose observation or treatment according to the specific cause and symptoms.

1Possible cause: External damage

The occurrence of skin fibroma is often related to local injury or friction of the skin. For example, mosquito bites, skin abrasions or inflammation after surgery can induce abnormal proliferation of fibroblasts and eventually form fibromas. Long-term chronic stimulation, such as repeated friction of clothing on the skin, can also cause similar consequences. Avoiding external stimulation and cleaning the wound in time are the key to prevention.

2Genetic factors and susceptible constitution

Some studies have shown that people with a family history of fibroids have a higher incidence of the disease, suggesting that genetic factors may be involved in the formation of the disease. Some people with more sensitive constitutions are also prone to abnormal proliferation of fibroblasts when facing slight external stimuli. For such people, they should pay more attention to skin care in order to reduce the chance of injury.

3. Autoimmune or hormone level factors

Some endocrine fluctuations and immune disorders may cause fibroids. For example, changes in hormone levels during pregnancy can increase the risk of certain skin lesions. In addition, people with weak immune function are more likely to overreact to external stimuli. It is recommended to strengthen nutrition and improve the body's immunity.

4 Symptoms of fibroids

Fibroids usually appear as single or multiple small round nodules on the skin surface, ranging in size from a pinpoint to a fingernail. They are often found on the outside of the calf or arm, sometimes slightly raised, hard and tough, and often brown, brownish yellow or light red in color. Generally, these nodules are painless and itchy, with clear boundaries from the skin, and may cause skin depressions when pressed.

5 Treatment and care recommendations

Mild skin fibroma usually does not require surgery and can be treated with regular observation. When rapid enlargement, ulceration or pain occurs, the following methods are recommended:

Medical treatment: Your doctor may recommend topical ointments, such as steroid ointments, to relieve local inflammation or reduce the size of the nodules.

Cryotherapy: Through low temperature treatment, fibroid cells are inactivated and eventually fall off.

Surgical resection: For larger fibroids or those that affect the appearance, they can be completely removed through surgery. After the operation, be sure to keep it clean to prevent infection.

Skin fibroma is mostly benign hyperplasia, and mild cases do not need to be overly worried, but if the symptoms worsen, you should seek medical attention as soon as possible to ensure your health and quality of life. Avoiding friction and trauma can reduce the probability of occurrence.
