title: 18q-syndrome and extraskeletal Ewing's sarcoma.
abstract: Cytogenetic studies carried out in a boy with multiple congenital anomalies showed a partial deletion of the long arm of chromosome 18. The child later developed an extraskeletal Ewing's sarcoma. The possible association of the tumour with 18q- syndrome is discussed.
