Abstract
Inherited bone marrow failure syndromes (IBMFS) present chronic bone marrow failures, a familial incidence and high risk of malignancy.
Objective: we describe our experience with patients with IBMFS. Since 02/73 to 02/05, 60 patients (pts) with IBMSF were diagnosed.

Conclusion: 68 % pts. presented with associated physical abnormalities, 53 % began the symptoms with bone marrow aplasia. With a median follow up: 16. 3 years (r: 1y – 32 y), 39 (65%) pts are alive (9 pts. post bone marrow transplantation) and 3 pts with Fanconi’s Anemia developed refractory Acute Myeloblastic Leukemia.
