Will dermatofibroma worsen and is it contagious?

Dermatofibroma usually does not degenerate into a malignant tumor and is not contagious. It is a benign tumor related to genetic inheritance, local irritation or minor trauma. It is usually not fatal or contagious and has relatively little impact on health.

Dermatofibroma is a hard nodule that occurs on the surface of the skin. It usually appears as brown or reddish-brown spots and is more common on the limbs. The main reason may be related to excessive inflammation repair after local injury. Some people are more susceptible to this lesion due to genetic tendency. The size of this nodule is usually in the range of 1-2 cm. It is hard and can slide freely. It is generally painless and itchy, but it may cause slight discomfort when subjected to external pressure or friction. Because dermatofibroma is a benign lesion, the cells will not spread rapidly or invade other organs, so the probability of malignancy and metastasis is extremely low. There is no possibility of systemic transmission of dermatofibroma. It is not a pathogenic lesion and naturally will not be transmitted from person to person.

For the management of skin fibroma, it is recommended to maintain observation as the main method. Treatment is usually not required when stable, but if the appearance affects confidence or the special location leads to repeated friction, surgical resection, cryotherapy or laser treatment can be selected to improve symptoms. Surgical resection is the most thorough, and the fibroma can be removed and a biopsy pathological examination can be performed to rule out malignant transformation; cryotherapy is simple to operate, and liquid nitrogen can be used to freeze the fibroma locally to cause necrosis and shedding; laser treatment is suitable for more superficial skin fibroma, and after treatment, attention should be paid to sun protection to prevent pigment deposition. For patients who are not suitable for surgery, drugs can also be used to soften the tumor, but physical treatment is still required for complete removal. Repeated friction of the fibroma site should be avoided in daily life, and if the fibroma grows rapidly, ruptures or repeatedly becomes infected, it is necessary to go to the hospital in time to check for the possibility of other serious lesions.

Dermatofibroma does not pose a serious health threat to most patients, but it is still necessary to observe and avoid further damage to the appearance or body by delaying treatment. At the same time, do not try to remove it by yourself or use folk remedies to avoid secondary infection or scar hyperplasia. Regularly checking the skin condition and taking appropriate treatment plans in combination with the doctor's advice is the best countermeasure.
