Ekbom Syndrome or Persistent Delirium with Somatic Symptoms: A Case Report

Introduction: Delusional infestation (DI), also known as delusional parasitosis or Ekbom's syndrome, is characterized by a patient's fixed belief that one's skin or other parts of the body or one's immediate environment are infested with small living or inanimate pathogens, against all medical evidence for this. The delirium of infestation can however be secondary to a medical pathology, which should be sought. Case report: A 52 year old morrocan women patient who has had paresthesias in her neck and her limbs for two years. She is convinced that she is infested by a parasite that she has been drinking in a glass of water. The evolution has been marked by an accentuation of the symptomatology and recent appearance in a month of an intermittent dysphagia to the solids. The psychiatric assemssment reveals a monothematic delusional syndrome systematized with total adhesion. The patient improved on atypical antipsychotic after eight week of treatment. Conclusion: This case of Ekbom syndrome demonstrates the importance of early management of pruritus or chronic burns and of the search for an underlying organic pathology, a delirium of infestation representing a potential complication. The most important problem is the clinical management of patients because they are often reluctant to engage in a meaningful therapeutic relationship.
