What does a Dermatofibroma look like?
Dermatofibromas usually develop slowly.
These small, hard, raised skin growths: Usually appear on the lower legs, but may appear on the arms or trunk.
May be red, pink, purplish, gray or brown and may change color over time..
Do all Dermatofibromas dimple?
Roughly 80 percent of all dermatofibromas will involute or withdraw below the surface of the skin when one applies lateral squeeze compression, creating a dimple in the skin. Although this “dimple sign” is not exclusive to dermatofibromas, it is still a very useful clinical sign.
Should I have a Dermatofibroma removed?
Most dermatofibromas do not require treatment. They can be safely left alone and will usually cause no symptoms aside from their appearance on the skin. However, some people still choose to remove them. Removal is especially common if the growth is unsightly or in an embarrassing place.
How does Dermatofibroma start?
Dermatofibromas are caused by an overgrowth of a mixture of different cell types in the dermis layer of the skin. The reasons why this overgrowth occurs aren’t known. The growths often develop after some type of small trauma to the skin, including a puncture from a splinter or bug bite.
What is DSFP?
Dermatofibrosarcoma Protuberans (DFSP) is a type of cancer called soft-tissue sarcoma and is rare. It forms in the skin’s deeper layers, typically on the torso but also on the arms, legs, head or neck.
Can you die from dermatofibrosarcoma protuberans?
Some people with dermatofibrosarcoma protuberans have cancer cells that produce an excess protein. A drug called imatinib (Gleevec) can target those cells and cause them to die. Your doctor may recommend this treatment if your cancer returns after surgery.
Is Dfsp life threatening?
The general prognosis for DFSP is excellent. In the past, recurrence rates were high, but with the introduction of Mohs surgery, those rates have decreased. Even with recurrent DFSP, Mohs surgery has a 98% cure rate. A poor prognosis is associated with metastasis.
What does dermatofibrosarcoma protuberans look like?
In dermatofibrosarcoma protuberans, the tumor most often starts as a small, firm patch of skin, usually 1 to 5 centimeters in diameter, that is usually purplish, reddish, or flesh-colored. The tumor typically grows slowly and can become a raised nodule.

How rare is Dfsp?
Dermatofibrosarcoma protuberans (DFSP) is a rare locally aggressive malignant cutaneous soft-tissue sarcoma. DFSP develops in the connective tissue cells in the middle layer of the skin (dermis). Estimates of the overall occurrence of DFSP in the United States are 0.8 to 4.5 cases per million persons per year.
Can Dermatofibromas be flat?
They may be slightly protuberant, but are most often flat, and are generally located on the extremities. One of the clinical attributes of dermatofibromas is their persistency, as they undergo few changes, if any, along a course of many years.
Can Dfsp spread?
They may increase in size more rapidly during pregnancy. If left untreated they can come through the skin, ulcerate and become painful. If they are not completely removed they will likely return in the same area. In very rare case or cases left untreated, DFSP can spread to other areas of the body.
What causes Dfsp?
The cause of dermatofibrosarcoma protuberans (DFSP) is unknown. Laboratory studies have shown that chromosomal aberrations may contribute to the pathogenesis of DFSP; however, no evidence of hereditary or familial predisposition exists. In 10-20% of patients with this tumor, trauma at the site seems to be incriminated.
