T25.731

Clinical Causes: Contact with corrosive chemicals such as acids, alkalis, or other industrial substances Chemical burns from accidental exposure in workplaces involving cleaning agents or manufacturing chemicals Persistently exposed to corrosive substances due to improper handling or storage Accidental splashes or spills during activities involving corrosive materials Self-inflicted injuries or trauma involving corrosive substances Environmental exposures in certain occupational settings or chemical spills

Key Symptoms: Severe pain initially, which may diminish as nerve endings are destroyed Dramatic discoloration of the affected toe, often darkened, charred, or leathery Swelling and significant redness around the injury Blackened or necrotic (dead) tissue indicative of tissue death Loss of sensation in the affected toe(s) Possible formation of blisters, ulcers, or open wounds Malodor if infection develops

Diagnosis Path: Visual inspection of the burn severity and extent Assessment of tissue damage and risk of infection Imaging tests such as X-rays to evaluate underlying bone involvement Laboratory tests if an infection or systemic response is suspected

Treatment Protocols: Immediate decontamination by thorough cleaning of the affected area to remove residual corrosive agents Pain management with appropriate medications Surgical debridement—removing necrotic tissue to prevent infection and facilitate healing Antibiotics to prevent or treat secondary infections Wound dressings tailored to support tissue healing and protection Tetanus prophylaxis if vaccination status is uncertain In severe cases, surgical procedures such as skin grafts or amputation may be necessary Rehabilitation therapies including physical therapy to restore function Long-term monitoring for complications such as infection or chronic wounds
