Dermatofibroma, Symptoms and Treatment of Dermatofibroma
What is Dermatofibroma?
Dermatofibroma is a general cutaneous nodule of unknown etiology which used to occurs more often in women. Dermatofibromas contain scar tissue and feel like hard lumps in the skin. The lesion frequently develops on the extremities (mostly includes the lower legs) and is usually asymptomatic, although pruritus and tenderness are not uncommon. Often these start out as red, turning later to brown, and sometimes itch. Dermatofibroma is basically a skin disease typical to youth, but Dermatofibroma may occur to the people at any age.
Dermatofibroma probably are a reaction to a minor injury, such a bug bite or a splinter. It is also known as Histiocytoma. A dermatofibroma is a very common, button-like dermal nodule, usually occurring on the extremities, important only because of its cosmetic appearance or its being mistaken for other lesions, such as malignant melanoma when it is pigmented.
What causes Dermatofibroma ?
The exact cause of Dermatofibroma is unknown but current thinking suggests that they develop from minor trauma like an insect bite. If removed and analyzed microscopically, dermatofibromas are found to contain very dense collagen. Dermatofibromas seem to be caused by some sort of injury, such as a bump, bug bite, or cut.
Dermatofibroma Removal and Treatment
In most cases, dermatofibroma require no treatment. Dermatofibromas can be removed surgically , but since they are deep, this usually leaves a scar.
Treatment of dermatofibromas should be considered when they get in the way of shaving or become irritated by clothing. In these cases surgical shaving of the top, punching out the center and maybe freezing with liquid nitrogen can be done. These treatments only destroy the upper part of the growth, and after a few years it may again become noticeable. If this happens, the treatment could be repeated again if desired.
