This is a claim of therapeutic success in five cases of exhibitionism without mention of the length of the period of observation. The treatment consisted of 'explanatory discussions and environmental manipulations'. For practical reasons cases of exhibitionism are divided in two groups, viz.: true exhibitionism (here called 'expomania, an entity in the compulsive neurotic group') and symptomatic exhibitionism, as for instance, isolated exhibitionistic activity at a time of a gonorrhoeal infection.
