Unremitting body odour: A case of Olfactory Reference Syndrome.

Olfactory reference syndrome (ORS) is a person's fear of exuding an offensive body odour which is not perceived by others. The objective of this case report is to highlight the challenges in diagnosing olfactory reference syndrome due to the lack of diagnostic criteria as well as its similarities to other psychiatric illnesses. We report a case of a young Chinese gentleman who was preoccupied with the belief that he had an offensive body odour which was not noticeable by others since the age of 10. As a result of this, he developed compulsive behaviour, social anxiety and avoidance, as well as depression. The patient had an array of psychiatric symptoms. He had symptoms which fulfilled criteria for obsessive compulsive disorder (OCD), delusional disorder somatic type, and social anxiety disorder. ORS remains a diagnostic challenge. Further studies are needed in this area for a better understanding of the disorder.
