Primary Anetoderma in an Infant: A Case Report From Southeast Asia

Anetoderma is an elastolytic disorder, categorized by singular or multiple areas of macules or papules, which can lead to the herniation of subcutaneous tissue. Anetoderma is rare, and its incidence is unknown. Primary anetoderma or idiopathic anetoderma occurs when there is no underlying associated skin disease with unknown pathogenesis. It can be classified into two major forms: (A) the Jadassohn-Pellizzari type and (B) the Schweninger-Buzzi type. Little is known about the specific pathophysiologic processes underlying anetoderma, although the phagocytic destruction of the elastic fibers has been postulated as a major role-player in the lesions. Our case highlights the incidence of primary anetoderma in a Southeast Asian adolescent girl with the onset during infancy that spread throughout the child’s development, without a family history of the disease.
