"Incomplete koro"- a forerunner for mood disorder: two case reports.

Koro was initially reported as a culture-bound psychiatric syndrome confined to South-east Asian cultures. Later on, isolated cases of Koro have been reported from non-Chinese cultures also. Incomplete Koro syndrome or a 'Koro-like state' is usually grafted on to a primary psychiatric disorder. The association of Koro with depression is rare and this paper reports two cases of mood disorder presenting with Koro symptoms. Recurrence of Koro symptoms in the depressive phase and its disappearance during the period of mania has not been reported. The initial anxiety associated with Koro might result into major depression. It is proposed that a Koro-like state may be a non-specific epiphenomenon that vanishes with recovery of depression.
