Dermatofibroma Information and Treatment
Dermatofibromas are harmless benign skin growths, found especially on the legs, that range in size from about 0.5 to 1 cm. These rounded bumps or hard papules vary in color from brownish to purple. Researchers believe that it can be caused by any injury of the past like a thorn pick or an insect bite. It can occur anywhere but predominantly found in exposed areas. Dermatofibroma are like an iceberg, they are more under the skin than on the skin. In the beginning it is red in color but later on turns brown and may even itch at times. Dermatofibroma is harmless and does not turn cancerous. Dermatofibromas occur most often in women the male to female ratio is about 1:4. Most physicians will advocate treatment only if the lesion is in the way of shaving, or is becoming irritated by clothing. Removal can be done surgically with local anesthesia , but since much of the growth extends beneath the surface of the skin, the scar may be larger and more noticeable than the original tumor. Cryosurgery may also be used to remove a dermatofibroma.
Dermatofibroma are common spots found frequently on the legs, but may occur on other sites such as the arms and trunk. A dermatofibroma is diagnosed by sight. The cause of dermatofibromas is unknown. These nodules are common in adults but are rare in children. They are firm and often feel like a stone under the skin. When pinched from the sides, the top of the growth may dimple inward. Dermatofibromas are usually painless, but some people experience tenderness or itching. Most often, a single nodule develops, but some people can develop many dermatofibromas. They rarely grow larger than a half-inch in diameter.
