Isolated Prothrombin Deficiency: A Case Report of a Rare Coagulation Disorder and Review of Literature.

Congenital prothrombin deficiency is a rare hemorrhagic disorder, frequent in areas with high degrees of consanguinity as it is autosomal recessive in nature. Clinical manifestations are highly variable, ranging from mild episodes of bleeding to severe hemorrhages. Here, we report a child with isolated prothrombin deficiency who presented with a history of pain and soreness in the prepuce associated with bleeding. Laboratory evaluation showed an altered coagulation profile with a prothrombin activity level of 29.8%, indicative of factor-II deficiency. This case highlights the importance of coagulation screening in all patients before even minor invasive procedures and the role of a detailed coagulation profile in confirming a diagnosis in the case of abnormal screening tests.
