Late ovarian relapse of TEL/AML1 positive ALL confirming that TEL deletion is a secondary event in leukemogenesis.

We describe here a late extramedullary ovarian relapse in an 18-year-old female who was diagnosed with hypotetraploid cell acute lymphoblastic leukaemia (cALL) at the age of 6. At both occurrences of the disease cells were analyzed by morphology, immunophenotyping, cytogenetics and molecular methods. TEL/AML1 was detected by RT-PCR and FISH analysis in both events.

Intratumoral consumption of indium-111-labeled platelets in a child with splenic hemangioma and thrombocytopenia.

The authors report Kasabach-Merritt syndrome (KMS) in a patient with thrombocytopenia and splenic hemangioma. A 13-month-old boy with a history of anemia, thrombocytopenia, and abdominal mass was admitted to the hospital. The scintigraphic studies showed that a large mass contiguous to the spleen was responsible for the platelet uptake.
