Factor v deficiency: a subtle presentation.

Congenital factor V deficiency (also known as labile factor or proaccelerin) is a rather uncommon [1:1000,000] inherited coagulopathy (autosomal recessive inheritance). Affected patients become symptomatic in early childhood with spontaneous or post-traumatic bleeding complications. The authors report an infant who presented with a much feared complication of the same probably as a neonatal presentation.
