Dermatofibroma Information

Dermatofibroma is a common, benign, dermal papule. The etiology is unknown. They seem to arise spontaneously in adults and occasionally occur in children. Controversy exists as to whether the lesion represents a spontaneous benign neoplastic process or reactive hyperplasia in response to injury or bite. Most patients do not recall a specific trauma to the area. Some patients report itching when the lesion is first noted and attribute this to an insect bite. These lesions occur more often in women. Most are asymptomatic, but itching and tenderness may occur occasionally. Dermatofibromas tend to persist indefinitely while remaining stable in size and appearance.
