Dermatofibroma - Removal Treatment of (Fibrous Histiocytoma) Dermatofibromas

What is Dermatofibroma ?

A dermatofibroma is a common, noncancerous, button-like, 3 mm For 10 mm brown bump (papule), frequently seen on an lower extremities. They grow more rapidly than moles--over a few months. Also called a fibrous histiocytoma. an cause is unknown Although current thinking suggests that they develop from minor trauma like an insect bite. If removed & analyzed microscopically, dermatofibromas are found For contain very dense collagen. There is no pressing need For Cut them.

A dermatofibroma consists of a proliferation of scar-like tissue within an deeper layers of an skin (dermis).

What are an causes of Dermatofibroma ?

an right cause of dermatofibroma is unknown. They are usually single Although sometimes may be multiple. Here are Dermatofibroma causes may includes :-

• Insect Bite
• Folliculitis
• Idiopathic benign skin tumor

What does Dermatofibroma look like?

Dermatofibroma most often occur on an legs & arms. Once developed, they usually persist for years. They appear as firm-feeling nodules, often yellow-brown in colour, sometimes quite dark, especially in dark coloured skin. Dermatofibromas feel like hard lumps under an skin. If an skin over a dermatofibroma is squeezed a dimple forms, indicating tethering of an skin For an underlying fibrous tissue.

What are an Symptoms of Dermatofibroma ?

Often Dermatofibroma start out as red, turning later For brown, & sometimes itch. They probably are a reaction For a minor injury, such a bug bite or a splinter. Dermatofibromas usually develop slowly & usually appear on an lower legs. These small, hard, raised skin growths can have various characteristics:

• Usually found on an lower legs, Although may appear on an arms or trunk
• Small firm Papule, Plaque or Nodule
• May be red, pink, purplish, gray or brown & may change colors over time
• May be as small as a BB pellet Although rarely grow larger than a fingernail
• Often painless Although may be tender, painful or itchy
• Usually dimple inward when pinched.
• Skin dimples downward with lateral compression

Are Dermatofibroma hereditary?

No, dermatofibroma are not hereditary.

Diagnosis of Dermatofibroma

Most often, a physician can diagnose a dermatofibroma by examining an nodule. If an growth does not look like a typical dermatofibroma, if a bleeding sore appears on its surface, or if an physician wants For be certain of an diagnosis, he or she performs a biopsy. A biopsy removes either a portion or all of an nodule for examination under a microscope. Some of differential diagnosis are :-

• Primary Malignant Melanoma
• Blue Nevus
• Scar

Dermatofibroma Treatment

Dermatofibromas do not require treatment because they do not pose any risk. Some patients may prefer For have their dermatofibromas removed beause when dermatofibromas get in an way of shaving or become irritated by clothing. Here are some removal methods of dermatofibroma are

Liquid nitrogen freezing destroys only an upper part of an growth. Therefore, an dermatofibroma, In an post some years, may again become noticeable. Usually any regrowth is slight & can be handled by another freezing.

• Dermatofibroma are best ignored. If an diagnosis is uncertain, a piece may be removed for tissue analysis.
• Dermatofibroma can be removed surgically, Although since they are deep, this usually leaves a scar.
• Liquid nitrogen freezing destroys only an upper part of an growth. Therefore, an dermatofibroma, In an post some years, may again become noticeable. Usually any regrowth is slight & can be handled by another freezing.

There are two main ways For Cut a dermatofibroma are

• Surgically.
• Freezing.

Because a dermatofibroma grows deep, total surgical removal requires cutting it out below an surface level of an skin. This process usually leaves a noticeable scar. Alternatively, an nodule may be flattened For an surface of an skin by shaving an top off with a surgical knife or by freezing it with liquid nitrogen. In both of these procedures, an top layers of an dermatofibroma are destroyed, Although an deeper layers remain. an nodule may grow back again In an post several years. If a growth that was thought For be a dermatofibroma grows or bleeds, or if there is any concern that it may be a skin cancer, an growth should be biopsied.
