    Juvenile Xanthogranuloma is a non-neoplastic skin lesion of the non-Langerhans histiocytosis type, which mainly affects the pediatric population and usually has a self-limited course. Exceptionally, the lesion is multifocal, ocular and even visceral, causing severe complications. We present the case of two 10-year-old female patients, with no other symptoms or important history, both with a single lesion, one on the thigh, with 3 months of evolution, the other on the scalp, with 4 months of evolution, both with progressive growth and surgically removed. The anatomopathological study identified multiple histiocytes in the dermis, with cytoplasmic lipidization and forming giant multinucleated cells, some of the Touton type, characteristic of this lesion. This unusual entity is reviewed, with emphasis on the histopathological criteria and the usual clinical course.El Xantogranuloma juvenil es una lesi贸n no neopl谩sica cut谩nea del tipo histiocitosis no-Langerhans, que afecta poblaci贸n principalmente pedi谩trica y usualmente de curso autolimitado.

Se presenta el caso de dos pacientes femeninas de 10 a帽os, sin ninguna otra sintomatolog铆a ni antecedentes importantes, ambas con lesi贸n 煤nica, una en el muslo, de 3 meses de evoluci贸n, la otra en cuero cabelludo, de 4 meses de evoluci贸n, ambas con crecimiento progresivo y extirpadas quir煤rgicamente. Al estudio anatomopatol贸gico se identific贸 m煤ltiples histiocitos en dermis, con lipidizaci贸n citoplasm谩tica y formando c茅lulas gigantes multinucleadas, algunas de tipo Touton, caracter铆sticas de 茅sta lesi贸n. Se revisa esta entidad inusual, con 茅nfasis en los criterios histopatol贸gicos y el curso cl铆nico habitual
