A 12-years old boy accompanied by a nurse working in social rehabilitation facility and police force was referred to Child Psychiatry Forensic Unit, of the medical School of Erciyes University, for psychiatric assessment. It was learned that the patient, his sister (19-years old) and one of their relatives (45-years old) had gone to a place approximately 2 months ago where the sister had acted as she was inserting a cucumber and eggplant to patient’s anus in accordance to instructions given by their relative and had sucked patient’s penis, and that the relative had watched the patient and patient’s sister. It was also found that similar events had repeated for two or three times within few days after first event and that these events were recorded by their relative using a camera. It was found that another person had learned about these events and informed the police force. In psychiatric assessment of the child, adjustment disorder was detected and medical therapy was initiated. The patient is still attending control examinations. It is rather difficult to recognize incest with vague symptoms after event and psychiatric symptoms may be important for detection of incest. Pediatricians should be careful in the routine examination of child in risk groups. Family practitioner, child psychiatrists, pediatricians and teachers if child is going to a school, should be one who first recognized potential incest. Thus, periodical certificate programs should be mandatory for primary care clinicians, healthcare providers and teachers. The number of child protection units will increase in parallel to the number of healthcare providers, trained about child abuse. This will guide for more appropriate approach to child abuse cases.
