Dermatofibroma: causes, symptoms and treatment

Dermatofibroma is a benign skin disease that
characterized by the appearance of single nodes on the skin. Dermatofibroma
formed from connective tissue fibers. It sprouts out
deep layers of the dermis, so this type of tumor belongs to
mesodermal lesions. Dermatofibroma has a physical,
brown or gray color, round shape, clear borders, dense
consistency and smooth surface. The tumor is characterized
slow growth and no tendency for malignant
rebirth. The size of the tumor can be very small, and
very large. In women, dermatofibroma develops significantly
more often than men. Fibroma localized on the back, upper
limbs, shoulders, feet.

The causes of the disease

The causes and mechanisms of the disease are not fully identified.
However, it is believed that dermatofibroma appears on those
skin areas that were previously damaged by bites
insects or after viral infections. Also
There are other versions of the occurrence of this disease. This
skin pathology is more common in people suffering from chronic
skin diseases. A number of experts are inclined to
hereditary factor in the development of dermatofibromas. Well known
cases of familial forms of dermatofibroma, Bushke-Ollendorf syndrome,
which is inherited in an autosomal dominant manner. Provoke
the development of this pathology can liver disease and
unfavorable ecological situation. The disease develops
mainly in adults after 30 years.


Symptoms of the disease

Dermatofibroma manifests itself in the form of smooth round knots, which
slightly rise above the skin. In most cases, its size is rare
goes beyond 1cm. Very often dermatofibroma is treated
their owners as a wart, since there is an external
the similarity between the two diseases. Most often formed
single nodes, but in the case of multiple formations, they
are located asymmetrically and scattered throughout the body.

Dermatofibroma can appear on any parts of the body, but more often
localized on the shoulders, forearms, back and legs. Color
gamma of nodules varies from solid, reddish-pink,
to yellow – brown and gray. Sometimes the color of the tumor does not have
monochromatic coloring: in the center it can be lighter, and
the edges are darker. Education is dense to the touch, has the property
move along with the skin. Subjectively, the disease itself does not
manifests: the tumor does not hurt and does not cause itching. But if she
located in a prominent place, and has a large size, it can
cause aesthetic discomfort.

Diagnosis of the disease

Typically, the diagnosis is not difficult, since
the disease has specific symptoms. But for
confirmation of the diagnosis in some cases necessary
additional tests. The most effective and accurate diagnostic method
– dermatoscopy. This method allows you to explore the tumor under
microscope for the detection of malignant pathology. In the same
purposes, a biopsy is performed with a histological examination of the cutaneous
material. This will help confirm the diagnosis and develop a follow-up.

Dermatofibroma Types

Dermatofibroma is classified according to histological and clinical
featured. Therefore, there are several types of this

  • sclerosing hemangioma, which is formed from a large
    the amount of vascular tissue;
  • cellular fibroma that is formed from collagen cells, with
    the prevalence of fibroblasts and histiocytes in the tissues (cells of loose
    connective tissue);
  • fibrous form, which is characterized by predominance in the tissues
    collagen cells and fibroblasts (cells not capable of dividing
    connective tissue formed from fibroblasts);
  • fibroxanthoma consists of typical xanthoma cells (cells,
    which are the final stage of the development of histiocytes) and
    Tuton’s multinucleated cells (giant cells that surpass their
    the size of the usual types of cells).

Dermatofibroma treatment

Dermatofibroma does not require treatment because it does not represent
danger to human life and health, and does not cause
no subjective feelings. The tumor is removed surgically.

removing this tumor does not always solve the aesthetic problem, so
how dermatofibroma germinates from the deep layers of the dermis and for its
removal is necessary to make a deep incision, after which

In order to avoid scarring, only excision is made.

To date, there are several ways to surgical
Dermatofibroma treatment:

  • Laser destruction. The most effective treatment method that
    leaves behind an inconspicuous scar. But since only deleted
    superficial part of dermatofibroma, relapse possible
  • Cryodestruction The tumor is frozen with liquid nitrogen, which
    leads to the destruction of its surface part. However, in this

  • The traditional classic method of tumor removal using
    a scalpel under local anesthesia helps to completely remove the tumor
    with the capture of healthy tissue. But in this case, as stated above,

In order to completely remove the scar, it is necessary to carry out
a series of additional procedures to achieve the desired aesthetic

excision of the scar on the skin, as well as dermabrasion and laser

In all cases, surgical treatment of the tumor is necessary
to conduct a histological study before the scheduled event. BUT
removed tissue must be sent for additional analysis during
avoidance of malignant pathology.

methods should be carried out only with permission and under
supervision of the attending dermatologist.

Forecast and prevention of dermatofibrosis

The prognosis of the disease is favorable, as this disease is
sound character and does not require regular monitoring with
hand oncologist. But patients with dermofibrosis need
self-examine yourself: follow the color,
size and growth of the tumor. At the slightest change of the above
characteristics urgently need to consult a doctor.
