Encephalopathy in an Elderly Patient Following Oral Ingestion of Topical Methyl Salicylate

Background: Methyl salicylate overdose is usually caused by frequent topical applications or accidental ingestion, especially in children. Case Report: A 77yearold woman was admitted with an altered mental status, mild fever, and tachypnea. Initial laboratory analysis showed metabolic acidosis with respiratory compensation without significant abnormal signs. On admission, hyperthermia was aggravated by antipyretics. On the second day after admission, one of her family members found methyl salicylate lotion in her cup, and she survived with hydration and conservative management. Conclusion: We report the first case of an elderly patient intoxicated by oral ingestion of topical methyl salicylate.
