Acute leukaemia in children--French-American-British (FAB) classification and its relation to clinical features.

A retrospective study of 45 patients of acute leukaemia in children (15 years age), in relation to FAB classification, is presented. Acute lymphoblastic leukaemias (ALL) were commoner than acute myeloid leukaemias (AML), with an ALL:AML ratio of 4.63:1. Amongst ALL, L1 was the most frequent type (59%), followed by L2 (35%) and L3 (5.4%), respectively. FAB types M2, M3, M4 and M5 were diagnosed ...

A Practical Guide to Differential Diagnosis of Small B Cell Lymphomas

Correct diagnosis and classification of lymphoid neoplasms depends on the integration of morphologic, immunophenotypic and molecular genetic features. The mature small B cell lymphomas despite their overlapping histomorphologies, have different clinical behavior and treatment. In this review, differentia...

French American British (FAB) morphological classification of childhood lymphoblastic leukaemia and its clinical importance.

As part of the Medical Research Council Leukaemia Trial UKALL VIII, 738 unselected children with acute lymphoblastic leukaemia (ALL) had the morphology of their marrow blast cells reviewed by a panel of three haematologists. Ninety four (13%) showed appearances classifiable as type L2 by the French American and British (FAB) cooperative group's criteria, five (0.7%) were typed L3, and the remai...
