Case ReportThe importance of laboratory re-evaluation in cases of suspected child abuse - A case report

- Physicians needs to be familiar with medical conditions that can simulate maltreatment.
- Interdisciplinary teamwork is necessary to match all investigation results with the present history.
- Petechial nature of bruisings are important suggestions for hematological diseases.
- Initial laboratory blood tests are necessary in context of non-accidental injuries.

In order to accurately diagnose child abuse or neglect, a physician needs to be familiar with diseases and medical conditions that can simulate maltreatment. Unrecognized cases of abuse may lead to insufficient child protection, whereas, on the other hand, over-diagnosis could be the cause of various problems for the family and their potentially accused members.Regarding child abuse, numerous cases of false diagnoses with undetected causes of bleeding are described in the scientific literature, but, specifically concerning leukemia in childhood, only very few case reports exist.Here, for the first time, we report a case of a 2-year-old boy who got hospitalized twice because of suspicious injuries and psychosocial conspicuities, in a family situation known for repeated endangerment of the child's well-being. After his first hospitalization with injuries typical for child abuse, but without paraclinical abnormalities, medical inspections were arranged periodically. The child was hospitalized with signs of repeated child abuse again five months later. During second admission, an acute lymphoblastic leukemia was revealed by intermittent laboratory examination, ordered due to new bruises with changes in morphology, identifiable as petechial hemorrhages.This case elucidates the discussion of known cases of leukemia in childhood associated with suspected child abuse in order to provide an overview of possible diseases mimicking maltreatment. To arrange necessary supportive examinations, a skillful interaction between pediatrician and forensic pathologist is crucial in the differentiation between accidental and non-accidental injury.
