Stria
Alternative names:
stretch marks; stria atrophica; striae distensae
Definition:
Skin defects that look like bands or lines, associated with rapid growth or certain diseases or conditions.
Considerations:
Stretch marks can appear when there is rapid stretching of the skin. They are often associated with the abdominal enlargement of pregnancy. They can be found in children who have become rapidly obese. They may also occur during the rapid growth of puberty in males and females. Stria are most commonly located on the breasts, hips, thighs, buttocks, abdomen, and flank.
Stretch marks appear as parallel streaks of red, thinned glossy skin that over time become whitish and scarlike in appearance. The stretch marks may be slightly depressed and have a different texture than normal skin.
Stria may also occur as a result of abnormal collagen formation, or a result of medications or chemicals that interfere with collagen formation. They may also be associated with prolonged administration of cortisone compounds, diabetes mellitus, Cushing disease, and post-pregnancy.
Common causes:
- pregnancy
- puberty
- obesity
- Cushing's syndrome
- iatrogenic Cushing syndrome
- topical corticosteroid overuse
- Prader-Willi Syndrome
- Laurence-Moon-Biedel syndrome
- Ehlers-Danlos syndrome
Note: There may be other causes of stria. This list is not all inclusive, and the causes are not presented in order of likelihood. The causes of this symptom can include unlikely diseases and medications. Furthermore, the causes may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as location, quality, time course, aggravating factors, relieving factors, and associated complaints.
