Differential diagnosis of coagulation abnormalities in borderline personality disorder.

We report the case of a 26-year-old woman suffering from borderline personality disorder (BPD), major depression and bulimia nervosa according to DSM-IV who showed unexplained impairment of the vitamin K-dependent coagulation pathway. Subsequently we discuss different manifestations of self damaging behaviour and comorbidities, as well as psychosocial issues potentially leading to coagulation abnormalities or complications in patients with BPD.
