The Auspitz sign is not a disease itself, but rather a clinical sign observed when a skin plaque is removed. It is characterized by the appearance of pinpoint bleeding spots.
Here's a breakdown:
Understanding the Auspitz Sign
- What it is: When a scale or plaque on the skin is scraped or removed, tiny points of bleeding can be seen.
- Appearance: It looks like small dots of blood, even if the skin hasn't broken and there isn't active bleeding.
- Why it happens: This sign indicates that the blood vessels in the underlying skin are very close to the surface.
Conditions Associated with Auspitz Sign
Although Auspitz sign is most commonly associated with plaque psoriasis, it is important to know that other conditions can also present with this sign, including:
- Plaque Psoriasis: This common skin condition is characterized by raised, red, scaly patches on the skin. The Auspitz sign is frequently observed when the plaques are removed.
- Darier's Disease: Also known as keratosis follicularis, this genetic disorder results in scaly, crusty papules. Auspitz sign might also be present here.
- Actinic Keratosis: These rough, scaly patches form on areas exposed to the sun. In some cases, Auspitz sign can be seen when removing these lesions.
