Dermatofibromas are hurtless benign skin growths, found mainly on the legs, that range in size from about 0.5 to 1 cm. Dermatofibroma (DF) is a general cutaneous nodule of unknown etiology that occurs mostly in women. The lesion normally appears on the extremities (mostly the lower legs) and is usually asymptomatic, despite of it pruritus and tenderness are not uncommon. The latest characteristic is seen in a sufficient number of patients to make DF the most prevailing of all painful skin tumors. Clearance of the tumor is not needful except diagnostic uncertainty exists or particularly troubling symptoms are present. They are stiff papules (rounded bumps) which may emerge in a variety of colors, usually brownish to tan. Typical dermatofibromas cause little or no discomfort, though itching and tenderness can develop.

Dermatofibroma is considered as a benign lesion; although, discomfort from pain or itching may be critical. Dermatofibroma can occur in patients of any age, but it normally rise in young adulthood. Approximately 20% of the lesions occur before age 17 years. DF is very likely better classified as a neoplastic process rather than a reactive tissue change. Though any cutaneous site can be seen, palm and sole participation is rare. Such known lesions were highly cellular, of large size, and localized. Indolent pulmonary metastases also were observed. The outermosts are the most common sites of involvement, specifically the lower legs. The few case reports of metastatic DF are doubtful from the point of view of past diagnosis.

Causes of Dermatofibroma

The cause is unknown but in some cases it arises at the site of a minor injury, mainly an insect bite or thorn prick. It is a form of urticaria in which skin welts forms along the lines where one has been scratched. They are normally single but sometimes may be multiple. Common causes of Dermatofibroma

• Insect bites.
• Minor injury or thorn pricks.

Symptoms of Dermatofibroma

There are usually no symptoms for dermatofibroma. It has cosmetic significance only and though it tends to exists for long term, it seldom causes any reactions. Usually only reassurance is needed. Sometimes its dark colour may raise anxiety about melanoma; if there is any doubt for its nature, the lesion can be excised for histology. Common Symptoms of Dermatofibroma

• Small, pea-sized growth.
• Itchy.
• Nodule.
• Dimpling.
• Painless.

Treatment of Dermatofibroma

Common Treatment of Dermatofibroma

• Shaving or is irritated by clothing, it can be flattened by freezing with liquid nitrogen.
• Intralesional steroid injections have been attempted with variable results.
• Cellulite cream thoroughly to the affected area, helps for fast recovery.
• Piece may be removed for tissue analysis.
• Cryosurgery may also be used to remove a dermatofibroma.
• Liquid nitrogen freezing destroys only the upper part of the growth.
• Apply Milk of Magnesia one on for ten minutes. Rinse off. A healthy low-fat, high fibre diet having plenty of fresh fruits and vegetables are beneficial home remedies of dermatofibroma.
