Overview
Dermatofibromas are harmless benign skin growths, found especially on the legs, that range in size from about 0.5 to 1 cm. Dermatofibromas are hard solitary slow-growing papules (rounded bumps) that may appear in a variety of colors, usually brownish to tan; they are often elevated or pedunculated.
Classification
Dermatofibromas are classed as benign skin lesions, meaning that they are completely harmless, though they may be confused with a variety of subcutaneous tumours. Deep penetrating dermatofibromas may be difficult to distinguish, even histologically, from rare malignant fibrohistocytic tumours like dermatofibrosarcoma protuberans.
Pathophysiology
Dermatofibromas are composed of disordered collagen laid down by fibroblasts.
Differential Diagnosis
Deep penetrating dermatofibroma may be difficult to distinguish, even histologically, from rare malignant fibrohistocytic tumors e.g dermatofibrosarcoma protuberans
Epidemiology and Demographics
Dermatofibromas occur most often in women; the male to female ratio is approximately 1:4. The age group in which they most commonly occur is twenty to forty-five years.
Risk Factors
The risk factors for development of dermatofibroma include:
- Thorn prick
- Insect bite
Complications
In rare cases, basal cell carcinoma may develop in a dermatofibroma.
History and symptoms
Although typical dermatofibromas cause little or no discomfort, itching and tenderness can occur.
Physical Examination
Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms.
Treatment
Most physicians will advocate treatment only if the lesion is in the way of shaving, or is becoming irritated by clothing.
Surgery
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.
