The demand for skin tissue allografts to treat burns and other types of injuries increases each year to the extent that categories of donors formerly deemed "unsuitable", such as victims of suicide by polytrauma or poisoning, are now considered. Patients who died by ingestion of/exposure to toxic substances can be accepted as tissue donors after assessment of graft safety to rule out any risks of transferring toxic substances to the recipient. A cadaveric skin donation was obtained from a 57-year-old woman who died from intoxication after ingesting colchicine tablets (0.2 mg/kg). To determine the safety of cadaveric skin allografts, high-performance liquid chromatography-mass spectrometry (LC-MS/MS) was used to identify and quantify colchicine in procured skin. Results revealed that colchicine concentrations were lower than the instrument limit of detection (LOD) of 0.5 ng/mg both in epidermis and dermis. Cell viability assessed through the MTT ([3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide]) test was within standard limits. Thanks to accurate tests performed, which are routinely applied also in clinical diagnostics and forensic toxicology, it was possible to ascertain the safety and suitability of skin tissue for donation.
