Factor X deficiency--a rare disorder.
Congenital factor X deficiency is a very rare inherited coagulation disorder. The clinical phenotype is of varying bleeding manifestations depending upon the level of factor activity. We describe a one and a half year old patient with severe deficiency (factor level less than 1%) who manifested with only easy bruisability and epistaxis that does not correlate with level of deficiency.
