Which condition is associated with the appearance of a herald patch?

• A. Eczema
• B. Psoriasis
• C. Pityriasis rosea
• D. Contact dermatitis

Answer: (C)

The condition associated with the appearance of a herald patch is pityriasis rosea. A herald patch is typically the first noticeable manifestation of this skin condition, presenting as a single, large, pink or salmon-colored lesion on the skin. This herald patch is often oval-shaped and can be mistaken for other skin conditions due to its appearance. Following the appearance of the herald patch, additional smaller patches may develop on the body in a characteristic pattern. Pityriasis rosea often resolves itself within several weeks to months and is believed to be caused by a viral infection, although the exact etiology is not well understood. Recognizing this condition early, particularly the herald patch, allows for appropriate management and reassurance to patients, as the condition is generally self-limiting. In contrast, other skin conditions such as eczema, psoriasis, and contact dermatitis have different presentations and underlying causes that do not feature the herald patch.
