[Acute lymphoblastic leukemia in children with Fanconi anemia].

Fanconi anaemia (FA) is a rare autosomal recessive disorder. Manifestation of the disease is pleomorphic and may include many congenital malformations and marrow aplasia. Congenital disorders include: skeletal abnormalities, hypo- or hyperpigmentation of the skin, renal or heart anomalies and many others. FA is an invariably fatal disease owing to progressive marrow aplasia or the development of acute leukaemia or squamous cell carcinoma. We present two children with Fanconi anaemia who developed acute lymphoblastic leukaemia in the 4 and 12 year of life.
