Pitfalls and Pearls in Delusional Parasitosis.

Clin Pract Cases Emerg Med 2019 Nov 14;3(4):387-389. Epub 2019 Oct 14.

Northwell Health, Emergency Department, Manhasset, New York.

Delusional parasitosis is an uncommon psychiatric disorder that manifests as having parasitic delusions. Due to its rarity, delusional parasitosis is a challenging and costly diagnosis of exclusion and proves difficult to manage for many providers. Although this syndrome is frequently discussed in psychiatric and dermatology reports, it is not commonly described in emergency medicine (EM) literature. Read More

Health providers induced iatrogenic delusions of infestation.

Clin Cosmet Investig Dermatol 2019 11;12:679-681. Epub 2019 Sep 11.

Department of Dermatology, University of Rochester School of Medicine and Dentistry, Rochester, NY 14642, USA.

Patients that suffer from factitial dermatosis mutilate their skin, often lacking any consciousness of self-injury, attributing the resulting lesions to spontaneous development. The case hereby described shows how the health providers' interventions led a patient from a baseline undiagnosed factitious disorder to frank delusions of infestation with , and a relentless search for antibiotic treatments. We highlight the need for educating health practitioners on the characteristics of psycho-cutaneous disorders. Read More

Lower Silesian Mental Health Center, Wroclaw, Poland.

Delusional parasitosis, also known as delusional infestation or Ekbom syndrome, is a relatively infrequent psychotic disorder characterized by an unwavering false belief that there is a parasitic infestation of the skin, despite the absence of any medical evidence that could support this claim. Delusional parasitosis can be categorized into primary, secondary, and organic forms. Sometimes, close relatives also experience identical delusions. Read More

Clin Dermatol 2018 Nov - Dec;36(6):748-755. Epub 2018 Aug 16.

Department of Psychiatry, Virginia Commonwealth University School of Medicine, Richmond, Virginia, USA. Electronic address:

Dermatologists often find themselves treating patients with psychiatric disorders, most commonly anxiety and depression, in the context of skin disease. The psychiatric condition may either be present before the skin condition developed and exacerbate it or, in some cases, even create it (eg, delusions of parasitosis). Alternatively, the psychiatric condition may occur subsequent to the development of the dermatologic condition. Read More

Authors:
Nicholas Laidler

Dermatol Online J 2018 Jan 15;24(1). Epub 2018 Jan 15.

Resident Medical Officer, Sir Charles Gairdner Hospital, Nedlands, Western Australia.

A large proportion of patients seen in dermatology practices have underlying psychological issues associated with their skin diseases. One of the most flagrant examples of this are patients with delusions of parasitosis. These patients have false fixed beliefs that they are infested by parasites and experience cutaneous sensations of crawling, biting, and stinging associated with their delusions. Read More

Somatic symptom disorder in dermatology.

Clin Dermatol 2017 May - Jun;35(3):246-251. Epub 2017 Jan 22.

Department of Dermatology, Oregon Health & Science University School of Medicine, Portland, Oregon.

Somatic symptom disorder (SSD) is defined by the prominence of somatic symptoms associated with abnormal thoughts, feelings, and behaviors related to the symptoms, resulting in significant distress and impairment. Individuals with these disorders are more commonly encountered in primary care and other medical settings, including dermatology practice, than in psychiatric and other mental health settings. What defines the thoughts, feelings, and behaviors as abnormal is that they are excessive, that is, out of proportion to other patients with similar somatic symptoms, and that they result in significant distress and impairment.

Background: Patients with delusional infestation (DI) believe that their skin is infested with organisms or inanimate particles, despite objective evidence to the contrary. Previous studies indicate a higher rate of recreational drug use among patients with DI. It is known that symptoms of infestation such as formication can be secondary to use of recreational drugs and alcohol. Read More

Obsessive-compulsive skin disorders: a novel classification based on degree of insight.

J Dermatolog Treat 2017 Jun 24;28(4):342-346. Epub 2016 Oct 24.

b Department of Dermatology, Psoriasis and Skin Treatment Center , University of California San Francisco , San Francisco , CA , USA.

Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive-Compulsive and Related Disorders. However there is evidence that other relevant skin diseases such as delusions of parasitosis, dermatitis artefacta, contamination dermatitis, AIDS phobia, trichotemnomania and even lichen simplex chronicus possess prominent obsessive-compulsive characteristics that do not necessarily fit the full diagnostic criteria of the DSM-5.

Department of Psychiatry, Academic Medical Centre (AMC), PO Box 1105 AZ, 1106 AZ Amsterdam, The Netherlands.

Patients with a delusional infestation (DI) have an overwhelming conviction that they are being infested with (non) pathogens without any medical proof. The patients need a systematic psychiatric and dermatological evaluation to assess any possible underlying cause that could be treated. Because they avoid psychiatrists, a close collaboration of dermatologists and psychiatrists, who examine the patient together, seems to be a promising solution. Read More

Deptartment of Psychiatry, Institute of Human Behaviour and Allied Sciences, Delhi, India.

Delusion of parasitosis is a rare condition characterised by an individual harbouring the delusion of being infested with insects or parasites. We report a rare and interesting case of delusion of parasitosis presenting as folie a deux, that is, the delusion is shared by both the parents of an 18-month-old child, with proxy projection of parental delusion on the child. The case highlights the rare concomitant occurrence of two psychocutaneous disorders and emphasizes the importance of early recognition and appropriate intervention to safeguard the well-being of the child.

Skin diseases (atopic eczema, psoriasis, idiopathic urticaria), systemic diseases (chronic hepatic or renal failure, morbus Hodgkin, diabetes mellitus) and psychiatric disorders (obsessive compulsive disorders, depression, delusions of parasitosis) can occur with itching. The aim of this review is to clarify the link between pruritus and psychiatric morbidity and emphasize the importance of a psychiatric consultation for patients with a chronic itching, without a skin disease. In the last years, there is a growing awareness regarding psychogenic itch, although these types of itch are significantly less studied in comparison to other types of pruritus. Read More

Children with a mother with delusional infestation--implications for child protection and management.

Pediatr Dermatol 2015 May-Jun;32(3):397-400. Epub 2015 Feb 2.

Department of Dermatology, Whipps Cross Hospital, Barts Health National Health Service Trust, Leytonstone, London, UK.

Delusional infestation (DI) is a reportedly uncommon psychocutaneous condition in which an individual holds a fixed, false belief of pathogenic infestation of the skin or body contrary to medical evidence. There are reports of such a delusion being shared with family members or close friends (folie a deux/famillie), but the implications of DI induced in children have not been discussed. We describe the case of a mother with DI whose children subsequently shared her belief. Read More

Delusional infestations: case series, differential diagnoses, and management strategies.

J La State Med Soc 2014 Jul-Aug;166(4):154-9. Epub 2014 Aug 12.

Department of Dermatology, School of Medicine, Louisiana State University Health Sciences Center in New Orleans.

Physicians are not infrequently consulted by distraught patients with delusions of infestation who believe that they are infested with external or internal parasites and describe a crawling sensation of bugs or worms on or under their skin. Internet search engines were queried with the keywords as search terms to examine the latest articles on delusional infestations in order to describe presenting manifestations, differential diagnoses, and effective management strategies. The demographic and behavioral features of delusional infestations have remained constant and include: (1) onset in well-educated, middle-aged adults who are pet owners; (2) production of purported specimens of causative parasites; (3) pesticide overtreatment of themselves, their households, and pets; (4) excessive cleaning or vacuuming of households; (5) intense anger and resentment directed at physicians failing to confirm their self-diagnoses; and (6) sharing delusional symptoms with spouses or relatives.

Dermatol Online J 2013 May 15;19(5):18169. Epub 2013 May 15.

UCSF Psoriasis and Skin Treatment Center, San Fancisco, CA 94118, USA.

When patients with psychodermatologic disorders present in clinic, the dermatologist can refer them to psychiatrists or other mental health care professionals. However, it is often the case that these patients will refuse a psychiatric referral because they either do not believe they have a disorder of psychiatric nature or they feel there is societal stigma associated with psychiatric illness. Therefore, it is essential for dermatologists to understand the common classifications for psychodermatological cases and to know how to optimally treat these patients with pharmacotherapy.
