title: Juvenile xanthogranuloma of the pelvic origin: a case report.
abstract: A case of juvenile xanthogranuloma (JXG) originating from the pelvic cavity is reported. The patient, a 4-month-old girl, was referred to our department for the examination and treatment of her left abdominal mass. As radiological studies strongly suggested the possibility of a malignant tumor of muscular origin, tumor extirpation was performed. The tumor was buried in the left psoas muscle. Histological examination showed the tumor consisted of polygonal cells containing small vacuoles with scattered Touton giant cells, and the diagnosis of JXG was made. To our knowledge, this is the first case of a pelvic JXG.
