What skin condition is signified by a positive Auspitz Sign?

A positive Auspitz sign is specifically associated with psoriasis. This sign refers to the appearance of pinpoint bleeding spots that occur when the scales of psoriatic plaques are removed. These spots occur due to the separation of the epidermis from the dermis, causing small blood vessels to be exposed.

Psoriasis is characterized by thick, red patches of skin covered with silvery-white scales, and these areas can bleed easily when scratched or when the scales are lifted. The presence of the Auspitz sign is a diagnostic indicator that helps healthcare professionals differentiate psoriasis from other skin conditions that may not present with this specific effect upon scale removal.

In contrast, conditions like eczema, dermatitis, and vitiligo do not typically exhibit the Auspitz sign, making this positive indicator quite specific to psoriasis. This makes the identification of psoriasis more straightforward during an assessment.
