OBJECTIVES
This poster aims to report a clinical case of a women with stalking behavior diagnosed with borderline personality disorder (BPD). We intend to review the relationship between this behavior and psychiatric diagnoses.
BACKGROUND
Obsessional following is a “stalking” behavior in which a person engages in an abnormal pattern of threat toward an individual. Because of the unusual and intense attachment seen in BPD, this diagnosis is particularly suggestive among stalkers. On the other hand, erotomania is a paranoid condition characterized by an individual's delusions of another person being infatuated with them. However, Meloy identified a specific type – Borderline Erotomania – to describe a sample of individuals who stalked their objects, but did not evidence erotomanic delusions.  
MATERIAL AND METHODS
Literature review by researching in PubMed articles. The key terms used were “stalking”, “erotomania”, “psychiatric characteristics”, “borderline personality disorder”.
RESULTS
A 40 years old women (Miss A), previously diagnosed with BPD, was admitted in November of 2018 duo to behavior changes. Miss A had 20 restraining orders against her, but in the last year it got worse – she started being more violently in her pursuit of Mr.X´s wife and started delivering threatening  letters and e-mails to the secretary of her former high school professor (Mr.Y). She explained that because of them, these men were never capable of being in love with her. She had abandoned her medication a year ago, and since then her behavior worsened.
CONCLUSIONS
In forensic samples of stalkers, rates of BPD are likely to be substantially higher. This case report is an example of some devious behaviors that these individuals can develop and perpetuate for years.
