Scabies and Nodules in Children: An Intriguing Entity

Nodular scabies (NS) is a relatively common variant of classical scabies whose pathogenesis is unclear. It is clinically characterized by pruritic, firm nodules most commonly involving the genitalia followed by axilla and groin region. A clinical diagnosis of NS is often straightforward. NS may persist despite the administration of antiscabicidal drugs such as permethrin and ivermectin. Topical and intralesional corticosteroids form the mainstay of treatment. Postscabietic nodule is a complication that primarily occurs in patients with previous history of scabies that had been successfully treated.
