ABSTRACT
Diesel is commonly used as fuel for engines and is distilled from petroleum. Diesel has toxic potential and can affect multiple organs. Exposure can occur after ingestion, inhalation or through the dermal route. The practice of siphoning diesel using a rubber tubing and the mouth is common in rural communities. This can lead to accidental ingestion and aspiration. Here we report a case of a patient who accidentally ingested diesel during siphoning, which caused extensive erosion of the oral cavity and oesophagus leading to pneumomediastinum and severe chemical lung injury. The patient responded well initially to steroids and supportive care but required prolonged hospitalisation. He developed complications of nosocomial infection and succumbed 23 days after admission.
