[Mixed bezoar]. / Bezoar mixto.

The case of an adolescent psychopath who, following traumatic psychological experiences, ingested her own hair and cotton string over a 6 to 8 month period, is presented. This resulted in the formation of a mixed bezoar (hair and cotton string) with subsequent deterioration of her general condition. The diagnosis was made roetgenographically. Curative surgery was performed and psychotherapy was initiated. A review of the current literature is made and the frequency, clinical characteristics, treatment, management and recommended prophylactic considerations are discussed.
