Abstract:
Coprophagia or the ingestion of feces, considered to be a variant of pica, has been associated with medical disorders like seizure disorders, cerebral atrophy, and tumors and with psychiatric disorders like mental retardation, alcoholism, depression, obsessive compulsive disorder, schizophrenia, schizoaffective disorder, fetishes, delirium, and dementia. But entomophagy or the practice of eating live or dead insects as food by humans has only been reported as part of eating habits by some cultures in the world and not in association with any medical or neuropsychiatric disorders. Till date, there is no report in medical literature of entomophagy as an association with any neuropsychiatric or medical illnesses. Coprophagy and entomophagy has not been together reported as well. We describe the first ever case report of a 19-year- old male patient diagnosed with undifferentiated schizophrenia and associated with both entomophagy and coprophagy. His schizophrenic symptoms, the entomophagic, coprophagic behaviors improved with olanzapine therapy. Entomophagy and coprophagy, two very unusual human behaviors, can be seen in association with schizophrenia.
