Erotomania, or De Clerambault's Syndrome, was first described in 1921. However, cases of Insane Love were long known before. Presently, this condition is classified as a delusional disorder typically affecting women. However, in forensic samples, most of these reports relate to men with violent behaviour, associated to harassing or stalking of a woman.

To present the case of a man, diagnosed with Erotomania and literature review of similar cases.

To bring awareness to the infrequent diagnosis of this condition in males and the legal implications this condition may have.

Consultation of the patient's clinical process and published articles focusing on Erotomania in men.

A 50-year-old man was referred from Court for persistently stalking a woman on the past few years. He revealed erotomanic and persecutory delusions, believing these accusations were all part of a scheme to restrain his alleged relationship.

There was a clinical improvement during hospitalization and treatment with antipsychotics. Due to the legal process in court, a forensic examination was also performed.

On the follow-up, the patient remained stabilized. He would not verbalize any delusional content, and calmly deny any inadequate behaviour. However, some of his stalking attitude remains. As many of these patients, we believe his delusion is still present, although his behaviour is more controlled with treatment. Recognizing the characteristics and course of this disorder in our patients, grants a better chance of intervention and attentiveness towards the legal implications that may arise.
