[Growth hormone deficiency and pituitary stalk interruption in Fanconi anemia].
Fanconi anemia is a rare disorder inherited by recessive autosomic transmission belonging to the group of chromosomal instability syndromes. It is characterized by progressively developing medullary aplasia, various congenital malformations and especially a high risk of cancer, particularly acute myeloblastic leukemia and certain solid tumors. The association is quite common in patients with endocrine disease which constitutes an additional factor of morbidity and must be diagnosed and treated. We report a case of Fanconi anemia revealed by severe delay in statural growth and primary amenorrhea with a 21-year-old girl. The diagnosis was suggested by asymptomatic pancytopenia caused by a medullary hypoplasia and confirmed by a cytogenetic investigation using cross-linking agents that showed a large number of chromosomal breaks. Hormonal exploration revealed hypopituitarism with complete growth hormone (GH) deficiency and hypogonadotrophic hypogonadism caused by interruption of the pituitary stalk. The aim of this case report is to illustrate the importance of early exploration of retarded growth which, in some patients, can reveal potentially serious, and treatable, disease.
