—In discussing the pathologic changes in eyes of children who died after suspected child abuse, Elner et al1asserted "that such trauma may be repeated is indicated by positive stains for hemosiderin"; this statement provides an opportunity for medicolegal confusion and miscarriage of justice. According to one source,2hemosiderin, a breakdown product of hemoglobin from red blood cells, may be identified as early as 1 day after injury, although other authors3are fairly circumspect and suggest that an interval of "several days" must pass before hemosiderin is deposited; macrophages that assemble ferritin into hemosiderin are identified at injury sites within 48 to 72 hours. Certainly, the detection of hemosiderin may indicate repeated trauma, but hemosiderin may also be a marker of survival after one episode of trauma. A child may be traumatized once and survive long enough for hemoglobin to be metabolized into hemosiderin.
