Hemophilia A and congenital hypofibrinogenemia: a rare association in same family.

Hemophilia A is the commonest inherited coagulation defect in human beings, whereas congenital hypofibrinogenemia is a much rarer disease. Occurrence of these two inherited diseases in the same family has not been reported so far. Younger sibling of a known case of Hemophilia A presented with recurrent, spontaneously occurring echymotic spots having prolonged PT, APTT, TT and very low absolute fibrinogen level with normal factor VIII level ultimately diagnosed as a case of congenital hypofibrinogenemia.
