"How Can I Tell If Its Vitiligo?"

The preliminary diagnosis of vitiligo can be made by observing the morphology, distribution range, and clinical symptoms of the white patches. If you suspect you have vitiligo, it is recommended to seek prompt medical attention and undergo relevant tests under the guidance of a doctor for a definitive diagnosis.

1. Morphology of White Patches: Vitiligo is a disease characterized by white patches on the skin due to the destruction of melanocytes. These patches typically appear as round or oval, light-colored with clear borders, and the edge pigmentation is often increased compared to normal skin.

2. Distribution Range: Vitiligo can occur anywhere on the body, but it is more commonly seen on exposed areas such as the face, neck, and back of the hands. It can also affect the lips, mucous membranes of the genitals, and the area around the anus.

3. Clinical Symptoms: Patients with vitiligo generally do not experience spontaneous discomfort. However, a minority of patients may experience localized itching at the affected area before or during the onset of the disease, which is often one of the early symptoms of vitiligo.

To confirm a diagnosis of vitiligo, Wood's lamp examination is used as an auxiliary diagnostic tool. Additionally, blood routine tests, trace element examinations, and Wood's lamp examinations can aid in differential diagnosis. Furthermore, medications such as clofazimine ointment and compound callizine tincture can be prescribed by doctors for treatment.

In daily life, it is important to avoid prolonged exposure to sunlight, practice sun protection, maintain a positive mindset, lead a regular lifestyle, and actively cooperate with doctors during treatment.
