Rev Med Liege 2019, 74(11),616-619Abstract : Inherited platelet disorders (IPD) include a set of rare diseases whose diagnosis is often difficult because it requires the use of complex biological assays in specialized centers. They are probably under-diagnosed. Clinicians should consider an IPD when facing a chronic thrombocytopenia resistant to intravenous immunoglobulins (IVIG) and steroids together with a family history of thrombocytopenia. A syndromic thrombocytopenia will be suspected by the family survey and specific clinical signs. The confirmation of the diagnosis will then require the use of specialized biological assays such as platelet aggregation, flow cytometry, electron microscopy, platelet secretion assays, karyotype and molecular biology.
