Organophosphates (OPs) are commonly used as pesticides throughout the world. 
Exposures to OPs cause a significant number of poisonings and deaths every year. 
Organophosphate-induced delayed polyneuropathy is a sensory-motor distal 
axonopathy which usually occurs after exposure of certain OP insecticides. 
Neuropathies due to ingestion of OPs have rarely been reported in the 
literature. Moreover, until now, there is no report of a patient developing 
organophosphorus injection-induced delayed neuropathy in the literature. We 
report a patient with serious organophosphorus-induced delayed neuropathy due to 
malathion injection. The patient was a 32-year-old female who self-injected 
undetermined amounts of malathion over the median nerve trace on the forearm 
crease in a suicide attempt which resulted in peripheral neuropathy.
