Secondary Koro Presenting as Delusional Disorder: A Case Series

Abstract

Koro, a culture-bound syndrome originating from Southeast Asia is characterized by a perception of acute retraction of the penis, accompanied by an acute panic-like reaction of impending danger or death. Koro-like symptoms are considered variants of classical Koro syndrome and differ from it phenomenologically. We described here a case series of secondary Koro, presenting as a delusional disorder who remitted on treatment with antipsychotics and maintained the improvement on follow-up. It is important to differentiate between classical Koro with Koro-like syndrome, with exploration of any delusional core during clinical assessment for better categorization and management.
