The present case report describes a juvenile xanthogranuloma in a five-month-old girl. A circumscribed papule was located below the right nasal ala and above the right vermilion border. The lesion was histologically diagnosed as a juvenile xanthogranuloma after surgical resection of the mass.

Extraskeletal Ewing's sarcoma in a great toe of a young boy.

Extraskeletal Ewing's sarcoma (EES) is a rare, soft tissue, malignant neoplasm histologically similar to skeletal Ewing's sarcoma. It occurs mainly in adolescents and young adults, and affects extremities in 36% of cases and central locations (commonly paravertebral regions) in the remainder. The differential diagnosis includes other small, blue, round cell tumours. A clinical case of EES involving a great toe in a young boy is reported. EES diagnosis was confirmed by features of histological analysis and immunohistochemistry, and by the presence of the t(11;22) chromosomal translocation.
