Arsenic exposure is classically associated with which finding?

Arsenic exposure is classically marked by changes you can see on the body, especially the nails and the gut. Mee’s lines are transverse white bands that appear on the fingernails after a period of arsenic exposure, signaling disruption of nail growth during toxicity. In acute arsenic poisoning, the lining of the GI tract suffers injury, producing hemorrhagic gastroenteritis with vomiting and GI bleeding. The combination of these nail changes and acute GI hemorrhage is a hallmark pattern that points strongly to arsenic exposure. Other findings point toward different toxins or conditions. Basophilic stippling with elevated ALA and FEP, for example, is more characteristic of lead poisoning. Kinky hair and related signs are not Arsenic-specific and can relate to other copper-related or nutritional issues, while neuropathy or convulsions can occur with arsenic but are not as diagnostic on their own as the nail lines plus GI hemorrhage.
