A rare case of chronic Gianotti–Crosti syndrome: A case report

Gianotti–Crosti syndrome, also known as papular acrodermatitis of childhood, is a common, self-limiting dermatosis often seen in children with triggers including viral and bacterial infections along with immunizations. Lesions are generally described as asymptomatic, skin colored to erythematous papules and papulovesicles that often spontaneously resolve within weeks. Here, we will discuss Gianotti–Crosti syndrome and present a rare case of chronic Gianotti–Crosti syndrome in an otherwise healthy 3-year-old male persisting for over 20 months. From this report, we aim to better educate the dermatologic community on the extremes of the Gianotti–Crosti syndrome disease course to improve diagnosis and treatment of symptomatic patients.
