Quack-induced dermatitis: A case report of two dermatitis artefacta induced by quacks advise.

This report delineates two instances of dermatitis artefacta (DA), a psychodermatological condition marked by self-induced or exacerbated skin lesions. These cases, triggered by treatments from non-qualified practitioners, highlight the critical need for healthcare professionals to discern the potential repercussions of unsound medical guidance.

Dermatitis artefacta: A diagnostic dilemma.

Dermatitis artefacta (DA) is a rare psychological disorder in which patients self-inflict cutaneous lesions to satisfy an emotional need. Here, we describe a case of DA initially misdiagnosed as pemphigus. This case represents the importance of the timely recognition and treatment of DA to prevent its progression like in our case scarring alopecia.

Marking nut dermatitis: A case series on factitious dermatitis.

Marking nut or Bhilawa is the fruit of plant Semecarpus anacardium Linn (Family; Anacardiaceae). It belongs to Semecarpus genera which also includes cashew nuts. It is closely related to Rhus and Toxicodendron genera, which includes poison ivy and poison sumac and causes similar skin reaction due to the presence of compound urushiol. Marking nut dermatitis is an uncommon problem but has special importance in military dermatology. Individuals can get exposed to this plant during camping which can result in an irritant or allergic contact dermatitis. It can also be applied deliberately to cause factitious dermatitis. We present 5 cases of factitious dermatitis resulting from application of marking nut.

Dermatitis Artefacta: A Challenging Case Report.

We report a 31-year-old female presented with a history of recurrent skin and oral lesions for 10 years. She brought a histopathology report confirming the diagnosis of pemphigus vulgaris (PV), which was found to be faked with no patient information and lacked letterhead. Skin and oral examination only reveal multiple linear upper lip erosions. We believed the patient had a preliminary diagnosis of PV, and we asked the patient to continue her medications. Based on the conflicting history and occurrence of contradictory issues, a diagnosis of dermatitis artefacta was made. The patient improved after four sessions of dialectical therapy.

Factitial dermatitis in the hospital setting.

Factitial Dermatitis (FD) is a notoriously difficult disease to diagnose, as patients produce self-induced cutaneous lesions and provide an inadequate or inaccurate history. We performed a cross-sectional study, querying an inpatient consultation database of all patients admitted to the Ohio State University Wexner Medical Center from 2012 to 2017 with a dermatologic ICD as a discharge diagnosis. Our exhaustive keyword search produced 189 candidates. Consult notes were thoroughly examined, and 32 patients were found to meet case definition of FD. Our analysis of this cohort revealed a significantly greater proportion of cases in the female population. Lesions were more often found to involve the skin on the upper extremities. Isolated secondary skin changes such as erosions, ulcers and excoriations in the absence primary morphologies were also significant in our cohort. As FD is difficult to identify, further understanding of its presentation pattern will decrease time to diagnosis and improve both hospital resource allocation and patient care.

Purpura with regular shape in an adolescent: Beware of dermatitis artefacta.

Background: Purpura is common in pediatric patients, mostly diagnosed as IgA-related vasculitis (Henoch-Schönlein purpura), idiopathic thrombocytopenic purpura (ITP), and thrombotic thrombocytopenic purpura (TTP). However, in some cases, for example, cases with dermatitis artefacta, it could puzzle a physician or pediatrician for a long time, with great challenges in diagnosis. Case presentation: We present the case of a 13-year-old boy with recurrent painful purpura on both upper limbs. The physical exam was unremarkable, except for right blepharoptosis and scars from burns. The diagnostic tests were normal. Through repeated communication, the patient was finally diagnosed as having dermatitis artefacta, accompanied by underlying psychological problems. Conclusions: Before dermatitis artefacta was diagnosed, we spent a lot of money and effort on the diagnosis. Therefore, in order to determine the diagnosis as soon as possible and save on unnecessary medical expenses, we propose a rapid process for the diagnosis of purpura of dermatitis artefacta in children.

Postherpetic Trigeminal Trophic Syndrome: A Case Report.

Trigeminal trophic syndrome (TTS) is a rare condition characterized by anesthesia, paresthesia, and facial ulceration involving the trigeminal dermatome secondary to self-manipulation of the skin after a peripheral or central injury to the trigeminal nerve or its branches. Differential diagnosis of TTS includes conditions presenting with chronic facial ulceration, such as various infectious diseases, malignancy, vasculitis, pyoderma gangrenosum and dermatitis artefacta. We report a case of postherpetic TTS and highlight the importance of early diagnosis and prompt treatment of this condition, which may commonly be misdiagnosed.

Dermatitis Artefacta, a Form of Factitial Disorder Imposed on Self, Misdiagnosed as Pyoderma Gangrenosum for Eight Years.

Dermatitis artefacta is a rare psychological disorder in which patients self-inflict cutaneous lesions to satisfy an emotional need. Due to the nature of this disease, patients can present with a wide array of sometimes very severe skin lesions. Here, we describe a case of dermatitis artefacta initially misdiagnosed as pyoderma gangrenosum and treated as such for eight years. The patient reported a long history of cutaneous ulcers on her extremities and trunk, with resultant extensive scarring. Upon presentation, she displayed rapidly progressing necrotizing skin lesions on her bilateral distal lower extremities. Both the skin manifestations and histologic sections were extremely atypical for pyoderma gangrenosum leading to extensive medical records review and subsequent diagnosis of dermatitis artefacta. This case represents the importance of the timely recognition and treatment of dermatitis artifacta to prevent its progression to severe harm and even death.

Occupational dermatitis artefacta: a clinical case in a flight attendant.

Dermatitis artefacta is a psychosomatic disorder characterized by cutaneous lesions that are self-inflicted by the patient, apparently due to itchy sensation. Usually, the patient denies any direct involvement with this condition and is rarely conscious of the underlying psychosomatic etiology. Authors report a case of a flight assistant with hypertrophic scars, symmetrically located on both upper arms. She referred chronic itchy sensation localized at the site where lesions were present; she referred relief only through continuous and forceful scratching. Considering the clinical history and after excluding other dermatological disorders, the diagnosis of dermatitis artefacta was made.

Trigeminal trophic syndrome: an important simulator of discoid cutaneous lupus erythematosus - a case series.

Trigeminal trophic syndrome occurs secondary to trigeminal nerve injury, leading to anaesthesia and paraesthesia, with consequent vigorous facial skin manipulation and lesion production, simulating other facial diseases such as ulcerative discoid lupus erythematosus, tumours and other artificially produced lesions. Ulceration and destruction of the ala nasi is a typical feature besides scratching end excoriations in the cutaneous segment affected. In this series, we present the features of five patients with trigeminal trophic syndrome, highlighting possible confusion with cutaneous lupus. Differential diagnoses, including discoid lupus erythematosus, are discussed, as well as possible treatment modalities.

[Bullous dermatitis with multinucleated keratinocytes in dermatitis artefacta: A case report]. / Dermatose bulleuse avec kératinocytes multinucléés révélant une dermatose factice : à propos d'un cas et revue de la littérature.

We report the case of a 13-year-old young lady with a one year reccuring bullous dermatitis history for which the diagnostic hypothesis of dermatitis arterfacta was made. This hypothesis was made by the pathologist, without it being suggested by the dermatologist, after observing singular histological lesions coresponding to a cutaneous blister associated with epidermic necrosis with multinucleated keratinocytes. When dermatitis artefacta is suspected, a biopsy is usually conducted to rule out differential diagnosis such as auto-immmune dermatitis when there is a blister. Confession from patients is rarely obtained. Therefore, having positive histogical clues for dermatitis artefacta would be of a great use to help making the diagnosis in difficult cases.

Cutaneous manifestation of IgG4-related disease mimicking dermatitis artefacta.

Dermatitis artefacta is a self-inflicted cutaneous disease presenting as sharply delineated ulcers, usually in accessible sites such as the head and neck. IgG4-related disease (IgG4-RD) is a recently recognised immune-mediated condition causing a fibroinflammatory process, resulting in the formation of tumefactive lesions in various organs, rarely presenting primarily in the skin. We report a case of cutaneous IgG4-RD clinically presenting as dermatitis artefacta.

Dermatitis artefacta mimicking cutaneous vasculitis: case report and literature overview.

A 31-year-old Caucasian woman with a history of anxiety disorder presented with chronic ulcerative lesions of the skin in arms and legs, treated initially as cutaneous vasculitis, evolving with relapsing during corticosteroid tapering, was diagnosed, after thorough investigation and no organic disease found, with dermatitis artefacta - a self-inflicted harm due to psychological disorders. Dermatitis artefacta is a rare condition, more frequent in women, in which traumatic skin lesions are caused by the patient him/herself, over accessible parts of the body, due to personality disorders. Clinicians should be aware of this alternative aetiology, especially as a differential diagnosis for refractory cutaneous vasculitis.

Dermatitis artefacta: self-inflicted genital injury.

BACKGROUND: The term dermatitis artefacta (factitious dermatitis, pathomimia) is reserved for the most severe variant of factitious physical disorder and is characterized by exaggerated lying (pseudologia fantastica), sociopathy, geographic wandering (peregrinating) from hospital to hospital, and seeking to be in the patient role. OBJECTIVE: This report aims to give attention to the importance of accurate and detailed history, and conducting an appropriate physical examination in patients with life-threatening diseases when the underlying cause is not apparent. The diagnosis of dermatitis artefacta must always be upheld. CASE PRESENTATION: We present a unique case of a 52-year-old male who presented to clinic with skin lesions on scrotum and shaft of his penis and that were very distinct and suggestive of pyoderma gangrenosum which he developed 3 months after previous discharge from the clinic. Clinical response to treatment and the absence of laboratory findings confirmed a dermatitis artefacta. CONCLUSION: Dermatitis artefacta is a factitious disorder that involves falsification of psychological or physical signs or symptoms caused entirely by the patients themselves, in a clear state of consciousness, in order to play the role of a sick person. The correlation of anamnestic data and clinical and para-clinical exams was essential for the diagnosis of dermatitis artefacta in this case. To the best of our knowledge, pyoderma gangrenosum-like lesions have never been reported in a patient with dermatitis artefacta. Herein, we describe a rare case report of self-inflicted genital injury in a 52-year-old male.

Ointment Pseudo-Cheilitis: A Disease Distinct From Factitial Cheilitis. A Series of 13 Patients From São Paulo, Brazil.

BACKGROUND: The terms exfoliative cheilitis, factitial cheilitis, and morsicatio labiorum are used to describe self-inflicted lesions of the lip. OBJECTIVE: Here we report and analyze clinical, pathological, and therapeutic data on 13 patients with a form of factitial cheilitis that we believe should be considered a separate entity. RESULTS: Eight patients were male and 5 patients were female. All patients reported pain and presented with crusts consisting of dried saliva and topical medications adherent to the surface of the lips. These patients expressed great concern with their condition, and reported several previous, ineffective treatments. Simple reassurance only was not effective; saline compresses alleviated symptoms for a few patients. Most patients were lost to follow-up. Biopsies were not performed on all patients. CONCLUSION: This particular type of cheilitis artefacta has been previously described, but some features described herein are new and allow a specific approach: patient's behavior, the "protrusion sign," and possible improvement with antidepressants. For these cases, we propose the term ointment pseudo-cheilitis because it comprises the nature of the attached material and the lack of true inflammation. Further psychiatric characterization is a logical next step in further characterizing this difficult-to-treat condition.

Dermatosis autoinfligida: presentación de un caso y revisión / Self-inflicted dermatosis: presentation of a case and review

Las dermatosis autoinfligidas representan un motivo habitual de consulta, así como un desafío diagnóstico y terapéutico. Se caracterizan por la autoprovocación de lesiones cutáneas de manera consciente o inconsciente en el contexto de trastornos psiquiátricos complejos. Comunicamos el caso de una paciente que consultó al Servicio de Dermatología por úlceras irregulares y sobreinfectadas localizadas en rostro, de 2 meses de evolución. El caso representó una dificultad diagnóstica ya que solo a partir del interrogatorio exhaustivo y los exámenes complementarios, que descartaron otras patologías, se arribó al diagnóstico de úlceras autoprovocadas en contexto de patología psiquiátrica que requirió manejo interdisciplinario. (AU)

Self-inflicted dermatoses are a frequent cause for consultation and represent a diagnostic and therapeutic challenge. They are characterized by the conscious or unconscious self-generation of cutaneous lesions in the context of complex psychiatric disorders. We report the case of a patient who consulted at the dermatology department with two months history of irregular and superinfected ulcers located on the face. This case represented a diagnostic difficulty since only from an exhaustive interrogation and complementary examinations, which ruled out other pathologies, we arrived at the diagnosis of self-inflicted ulcers in the context of psychiatric pathology that required interdisciplinary management.

Dermatitis Artefacta Mimicking Borderline Personality Disorder: Sometimes, Skin Could Be Misleading.

Dermatitis artefacta lies in a gray zone, between the specialities of psychiatry and dermatology. The condition could mimic a number of other lesions and therefore is a source of much confusion in clinical practice. Here, we describe a case of dermatitis artefacta in an 11-years old girl, which resembled self-harming behavior in Borderline personality disorder. We then discuss how the two could be differentiated and why this becomes imperative while dealing with such cases.

Epidermal multinucleated keratinocytes: a histopathologic clue to dermatitis artefacta.

Dermatitis artefacta is a psycho-cutaneous disorder characterized by self-inflicted cutaneous injuries, often in association with an underlying psychiatric disorder or as a response to external stressors. Cutaneous lesions suggestive of dermatitis artefacta are dependent on the means of injury and thus may be morphologically variable, but typically have geometric shapes, spare hard-to-reach anatomic areas, and are present in variable stages of evolution at any specific time. Although a dermatologist may be suspicious of dermatitis artefacta in a given patient, making a definitive diagnosis is extremely challenging. Patients often clinically evade questioning and deny creating skin lesions, and histopathologic evaluation of lesional biopsies usually reveals non-specific epidermal and dermal changes and inflammation. Thus, identification of clues that lend support to a diagnosis of dermatitis artefacta would be welcomed by both clinicians and pathologists. Here we present a case of dermatitis artefacta with a unique, yet previously reported, histopathological finding of multinucleated keratinocytes within the epidermis. Although probably uncommon and dependent on the etiology of cutaneous injury, we believe this finding is important for dermatopathologists to be aware of as a potential diagnostic clue when evaluating biopsies in patients suspected to have dermatitis artefacta.
