Nausea of ​​the sebaceous glands of Jadasson - causes, symptoms, treatment, photos

Nevos Jadasson in dermatology is called a tumor-like formation due to malformation of the sebaceous glands( in the first place), as well as other elements of the skin( connective tissue, apocrine glands, hair follicles).

In 70% of cases, nevus Jadasson is a congenital form. In

, in other cases, education develops in the thoracic and, extremely rarely, in later childhood. Nevus Jadasson in most cases sporadic education, however, sometimes there are family cases. Distribution by race and gender is the same.

In most patients, the neuve sebaceous glands are formed on the scalp( usually on the verge of hair growth) on the face. In other places, this education develops rarely.

Causes of development of

What causes the development of nevus Jadasson, to date, has failed to find out. One of the known causes is hyperplasia of the sebaceous glands.

Clinical picture of

Manifested by the nevus Jadasson, the formation of a flat solitary plaque is oval or( less) linear in form. The consistency of education is mildly elastic, the color is pink, yellow, sandy or pale orange. The surface of skin education may be uneven, papillomatous. Sometimes there are signs of keratosis and flaking of the epidermis with large scales.

Developmental stages and clinical manifestations of the nevus are determined by the age of the patient:

  • In childhood, nevus Jadasson has a smooth or papillary surface. Growth of hair on this area of ​​skin is absent.
  • In adolescents, the dermal form is altered - the hearth can become larger, its surface is covered with furrows. The color of education becomes more pronounced - yellowish or pinkish-white. In some patients at this stage of development, the nevus becomes painful and very easily injured. And very often this nevus bleeds, although it is difficult to notice it.
  • Reproduction of education may occur in mature patients. Approximately 20% of patients are observed in the thick nevus tumor growth. The tumor may be benign and be one of the forms of cancer. More often, nevus tissues are reborn in hydradenum, papillary or apocrine cystadenome, keratocentamic, basaltic, apocrine gland cancer, or squamous cell carcinoma. The sign of tumor growth is the formation of new nodules in the tissues of the nevus or the development of erosion on its surface.

    Nevus Jadasson can often be reborn in the basal.

    One of the most common variants of the rebirth of the neuve of the sebaceous glands is the development of basalemia. This type of tumor develops in the nevus Jadasson's tissues much more often than benign tumors. Some patients have a development of both benign and cancerous tumors.

    It should be noted that with malignant degeneration of nevus Jadasson, the disease proceeds with a lesser degree of aggressiveness than usual. Metastyses tumors in the degeneration of the nevus of the sebaceous glands only in exceptional cases. There is a theory that the development of basalomy against the background of nevus Jadasson is not a malignant transformation. Researchers consider rebirth as differentiation of epithelial cells and increase their proliferative nature.

    A rare case is the common salivary nevus. In this case, the disease is systemic. In addition to skin symptoms in patients, there is a vascular system, eye, central nervous system, etc.

    In exceptional cases there is a syndrome of sebaceous nevus Jadasson, characterized by a triad of symptoms: epilepsy, mental retardation, nevus sebaceous glands of the linear form.

    Diagnosis of

    Diagnosis of sebaceous nevus is based on histological studies. Formations with this pathology have a lobar structure and consist of tissues of the sebaceous glands. Education is located in the middle or lower part of the dermis. In addition, enlargement of the axes of the apocrine glands may be observed.

    Depending on the histological picture, there are three stages of development of education:

    • At an early stage hyperplasia of hair follicles and sebaceous glands is observed.
    • At the next stage, which is considered mature, manifestations of acanthosis. In the epidermis there is a case of papillomatosis, a large number of sebaceous glands with signs of hyperplasia. Hair follicles are underdeveloped, and apocrine glands are well developed.
    • The last stage of development is tumorous. Histologic picture at this stage depends on the type of developed tumor.

    Nevus Jadasson should be distinguished from:

    • From aplasia of the skin. In this case, the illness of education is characterized by a smooth surface.
    • From Papillary Syringogocystadenomatous Nevus. This type of nevus is characterized by intense pink spotted color and pronounced nodal surface.
    • From juvenile xanthogranuloma, in which education has a dome-like shape and is characterized by rapid growth.
    • From solitary mastocytoma, which differs from the sebaceous nevus by the histological structure.

    Treatment of

    Due to the fact that the risk of nevus tissue transformation is high enough, it is recommended to remove this formation until the age of puberty.

    A surgical method is used to treat the disease.

    It is necessary to use a surgical operation, as more gentle methods( cryodestruction, electrocautery, etc.) lead to a re-growth of education.

    A complete nevus excision is required within a thin strip of healthy tissue. If it is impossible to carry out an operation at one time, they produce a phased removal of pathological tissues with minimal interruptions between operations. Since the salivary nevus is usually located on the head or person, the operation to remove it is considered complicated.

    The operation for the removal of education is carried out in medical institutions specializing in the treatment of cancer. Distant tissues are sent to the histology, which allows to determine the nature of the formation and to detect or exclude the presence of atypical cells, indicating the beginning of the process of malignancy.

    Removal of education is carried out under general or local anesthesia depending on its size, location and age of the patient. After removal of pathological tissues on the edge of the wound apply seams. With a large size of education or at its location on the face of the tricks used plastic surgery, with an overlay on the place of a defect of the skin of the skin.

    A sterile bandage is applied to the place of surgery, and then it is necessary to make bandages for a week and to treat the postoperative wound with antiseptics. Seams are removed after healing of the wound. After radical removal of nevus Jadasson, no relapse was observed.

    Prevention and Prognosis

    There are no measures that could prevent the formation of nevus Jadasson, as the causes of its development are unknown.

    Forecast in most cases is favorable. Approximately 10% of patients develop nephros in the basal region. Less education is reborn in sebaceous or apocrine gland cancer. Prevention of tissue malignancy of education, it is recommended to remove it until the age of 12 years of the patient. After a radical operation, recurrence and development of the basalomy on the site of the remote nevus was not noted.
