The appearance of one white stripe on the patient’s body should be specifically analyzed in the clinical context. If the patient does not feel anything and the condition has been present for a long time, it should be considered that atrophic striae have occurred. Atrophic lines are caused by changes in the patient’s own hormone levels, as well as sudden weight gain changes, resulting in the breakage of the subcutaneous elastic fibers, which will appear on the surface of the skin in the form of depressed scar tissue. Other patients have white streaks on their bodies as a symptom of skin allergy, urticaria, where the white streaks appear on the scratched areas of the skin. Some patients may have a pronounced itching sensation, but others may have no symptoms at all and may have erythema around the white streaks. Other patients may have a white streak that is a localized hypopigmentation left over from other previous inflammatory changes when the inflammation fades. For example, in clinical practice, a patient may have had thread-like moss, which starts out as a small, linearly arranged papule, but in patients who are darker in color themselves, white streaks may appear after the symptoms subside.
