They are rare and often associated with malformations which are of great diagnostic value. The Fanconi syndrome is a well individualized form in which aplasia of the bone marrow is combined with various malformations which are of great diagnostic value. The Fanconi syndrome is a well individualized form in which aplasia of the bone marrow is combined with various malformations, particularly skeletal, cutaneous and renal.
