Factitious disorder and malingering in adolescent girls: case series and literature review.

Six cases of factitious disease and malingering in pediatric patients referred to an infectious diseases practice in a tertiary care children's hospital are described, and implications for general clinical practice are reviewed. All patients were girls aged 9-15 years. Two patients were malingering with the secondary gain of avoiding attendance at school. The other 4 patients presented with factitious illness without clear link to secondary gain, but rather for a psychological purpose. Three of the subjects admitted to self-induced or feigned illness. The 2 patients diagnosed with malingering did very well with early parental support, psychotherapy, and attention paid to school difficulties. The outcomes of the others with underlying psychological conflicts were less resolved. Factitious disorders and malingering occur in the pediatric population. A high index of suspicion is needed for prompt diagnosis and care.
