Thyroid dermopathy and acropachy in pediatric patients.

The extrathyroid manifestations of Graves disease (GD) include thyroid orbitopathy, dermopathy, and acropachy. Thyroid dermopathy (TD), also known as pretibial myxedema, classically presents as nonpitting edema or plaquelike lesions on the pretibial region, while thyroid acropachy (TA) is seen in cases of severe TD, characterized by soft tissue swelling and clubbing of fingers and toes, as well as a periosteal reaction of the bones of the hands and feet. Both TD and TA are rare manifestations of thyroid disease and uncommonly reported in pediatric patients. Our aim was to increase awareness of dermatological manifestations associated with pediatric GD and review the literature of pediatric thyroid dermopathy as well as report a case of acropachy in a child.
