A herald patch is a term used to describe a large, scaly, and often circular or oval-shaped patch of skin that appears on the body. It is typically the first sign of a skin condition known as pityriasis rosea. In this article, we will explore what a herald patch means, its causes, symptoms, diagnosis, and treatment options.
What is a Herald Patch?
A herald patch, also known as a mother patch, is a distinctive skin lesion that is characterized by its size, shape, and appearance. It usually starts as a single patch, which is larger than the subsequent patches that may develop. The patch is often round or oval-shaped and has a well-defined border. It can range in size from a few centimeters to several inches in diameter.
Herald Patch Causes
The exact cause of a herald patch is unknown, but it is believed to be associated with a viral infection, particularly the human herpesvirus 6 (HHV-6) or human herpesvirus 7 (HHV-7). These viruses are common and can cause various symptoms, including skin rashes.
Herald Patch Symptoms
The most common symptom of a herald patch is the appearance of a single, scaly, and pink or red-colored patch on the skin. The patch is usually located on the trunk, but it can also occur on the arms, legs, or neck. It may be itchy or tender to the touch. In some cases, additional smaller patches may develop around the herald patch in a pattern that resembles a Christmas tree.
Herald Patch Diagnosis
A dermatologist can usually diagnose a herald patch by examining the affected area of the skin. The distinctive appearance of the patch, along with the presence of smaller patches in a Christmas tree pattern, is often enough to make a diagnosis. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other skin conditions.

- Topical corticosteroids to reduce inflammation and itching.
- Oral antiviral medications to target the underlying viral infection.

It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan.
