Included in this title, the demonstrations that can be expressed as a complication of sebum sebum at puberty, the latter including educational reasons, not because they are themselves, lilipidización disorders, and discuss later.
1. Introduction, symptoms and signs:
Entering puberty begin the following changes:
A) The changes become more evident, especially in the face.
B) The appearance of the skin is shiny, especially the nose. Sometimes when the flow is heavy, oily droplets were observed covering the face:
• We altering evidence supporting the skin tissue paper that is covered by patches.
• pilosebaceous orifices of the nostrils are considered the elementary lesion of seborrheic dermatitis (comedo filament are not the same, we'll see).
C) The growth of hair.
2. Location:
The first changes are apparent in the wing of the nose (nostrils), then in the nasolabial fold; the middle frontal and superciliary region, cheeks, preauricular and chin (da wing aspect clover).
also observed in the body and the back region, extending to the shoulders, around the neck and into the lower lumbar region (given aspect of a cross) and the scalp.
not attack nor the area of \u200b\u200bthe eyelids, or the outer region of the cheeks.
3. Evolution: Begins
demonstrations prepuberil age, ten or twelve years, especially in the area near the nose, and extends to the face and body to reach its maximum stage, in his youth.
In adults, it tends to decrease, but often the appearance of oiliness in the middle (between the eyebrows, nose, cheeks near the nose), chin and skin
Alip and irritable side of the cheek area.
4. Seborrhea grades:
intensity changes can occur in very different degrees:
• In the skin of many adolescents, will be barely noticeable, remaining essentially normal (compare with the one without seborrhea).
• The other end of the faces of girls who are suspended for one day facial cleansing, and skin that is thick and congested, it begins to fill with oily coat
• Most are intermediate cases, corresponding to the description of the introduction to location on the face and discreetly.
5. Seborrhea normal or physiological puberty:
are reminded that the stimulation of androgens, which increase in men at puberty, increased activity of sebaceous glands. We will see that this response is normal, transient and no alterations in the composition of sebum.
6. Alterations in the composition of sebum:
Increased cholesterol esters. The pH is increased, decreasing the skin's protective activity.
7. Microscopic alteration of the skin:
• There's cornification of the skin or hyperkeratosis. Sebaceous
• The core (central lesion) consists of fat, there are also mites and bacilli. In adults, the filaments can be replaced by very similar elements, placed in the pores, similar in appearance to black spots or blackheads and are penachitos hair, very close, in compact form (this is from a physiological process called tricostásia) .
8. Etiology:
androgen-estrogen imbalance in favor of the former, an increase of androgens, or estrogen decrease, or decreased tissue sensitivity estrogen or increased sensitivity to androgens. In determining individual sensitivity of tissues to these hormones other factors: diet, metabolic, genetic, etc., We will see in the cause of acne that predispose both seborrhea and acne.
