Lymphoblastic extramedullary spinal tumor during remission of acute lymphoblastic leukaemie

An unusual case history of a girl with ALL is presented. The diagnosis was established at the age of 7. At the age of 11, 5 years and 3 months after remission due to treatment an extramedullary tumour of a lumbar vertebra produced a transverse lesion of the spinal cord and meningeal leukaemia. The tumour consisted mainly of connective tissue with small foci of lymphoblastic cells, identical with those originally seen in the peripheral blood stream. After laminectomy, irradiation and chemotherapy the girl is still in her first haematological remission, lasting nearly 7 years.
