Herald Patch

Herald Patch

A herald patch is a distinct skin manifestation characterized by a single, erythematous, round to oval scaly patch or plaque. The patch has a depressed center and raised border and measures 2 to 10 cm. The lesion typically exhibits a predilection for the neck, chest, and back. As the lesion evolves, it tends to clear centrally, leaving the free edge of the scale. This reveals a unique “collarette” of scale, which is a common presenting sign of pityriasis rosea—a prevalent and self-limiting papulosquamous disorder. This clinical presentation resembles the edge of a cigarette paper directed inward toward the center.The sign is called the “herald” patch or “mother” patch because it often appears a few days to 2 weeks before the complete eruption of pityriasis rosea. This activity reviews the etiology and evaluation of pityriasis rosea, emphasizing the importance of the interprofessional healthcare team in treating patients with herald patches. This activity highlights the roles of participating clinicians in assessing the rash distribution, frequency, and progression predictability, with optimal coordination among primary care and dermatology consultation as necessary.
