The Cutaneous Manifestations of Drug Reactions Can Mimic Traumatic Injuries: Case Reports and the Potential Role of...

The evaluation of the skin of the decedent is an essential component of the assessment by the forensic pathologist or the medical examiner. Age-associated cutaneous changes, primary diseases of the skin, and systemic conditions with mucocutaneous manifestations can be present. Importantly, several dermatoses can be misinterpreted for traumatic injuries; specifically, adverse reactions to medications can mimic assault, burns, elder abuse, and mutilation or torture. A male with corticosteroid-induced dermatitis mimicking an acute burn is described. A female with thalidomide embryopathy is reported with extensive deformities of her hands and feet with multiple absent digits mimicking a severe injury resulting from mutilation or torture. Another female is described who had hydroxychloroquine-associated hyperpigmentation; her physician misinterpreted the cutaneous hyperpigmentation as bruises and notified Adult Protective Services. Reactions to medications can also mimic assault, burns, and elder abuse. Drug reaction with eosinophilia and systemic symptoms (particularly when associated with phenytoin) can mimic assault. Albeit rarely, the antihypertensive irbesartan can result in dramatic edema of the face and eyelids similar to that observed following an assault. Drug-induced erythema multiforme can mimic a localized burn, and Stevens-Johnson syndrome or vancomycin infusion reaction can mimic an extensive burn. Several medications can mimic bruising observed in victims of elder abuse; they include amiodarone, arsenic, and tetracyclines (such as minocycline and doxycycline). In summary, an important aspect of the forensic evaluation during an autopsy includes a complete cutaneous examination; to aid in differentiating medication-associated dermatoses that can mimic traumatic injury, the evaluation of the decedent by a forensic dermatologist may be helpful to establish the etiology of observed skin changes.
