Combined factor VIII and IX deficiency: An exceptional case

Abstract

Familial multiple coagulation factor deficiencies are a group of rare inherited disorders that are characterized by the simultaneous decrease in the levels of two or more coagulation factors. Common synchronous deficiencies are factors VIII and IX and combined deficiency of Vitamin K-dependent coagulation factors (factors II, VII, IX, and X). Here, we report a case of synchronous dual deficiency of factor VIII and IX, which is an extremely rare occurrence and no case report has been mentioned so far to the best of our knowledge. Recognizing such a dual deficiency is very important for proper management of patients.
