Congenital isolated juvenile xanthogranuloma of the sole - a unique case report in a newborn.

Juvenile xanthogranuloma (JXG) is a rare, benign non-Langerhans cell histiocytosis that primarily affects the skin, with infrequent extracutaneous manifestations. Lesions typically emerge during early childhood and often resolve spontaneously, obviating the need for treatment. This paper details the case of a child diagnosed with a solitary JXG on the sole, necessitating surgical excision due to its functional impairment, specifically a delay in walking and weight bearing.
