Overview
Psychogenic sensory disturbances of the skin involve tactile or painful sensations without an identifiable organic cause, often linked to psychological factors. These conditions can manifest as dermatitis artefacta or other self-inflicted skin lesions, reflecting underlying psychiatric issues such as anxiety, depression, and personality disorders 123.Diagnosis
Clinical Presentation: Deliberate production of skin lesions, often on visible areas like the face and upper body 2.
Psychological Assessment: Underlying psychiatric diagnoses such as anxiety, depression, and personality disorders 2.
Differential Diagnosis: Rule out organic causes of skin symptoms through dermatological examination and relevant tests 3.
Patient History: Detailed history focusing on psychological stressors and behavioral patterns 13.Management
First-Line Treatments:
- Psychotherapy: Cognitive-behavioral therapy (CBT) and other psychotherapeutic approaches to address underlying psychological issues 13.
- Psychological Support: Building a therapeutic alliance and providing emotional support 1.
Adjunctive Treatments:
- Antidepressants: For managing depression and anxiety, e.g., SSRIs 1.
- Anxiolytics: Short-term use for severe anxiety symptoms 1.
- Antipsychotics: In cases with psychotic features or severe behavioral disturbances 1.Special Populations
Pediatrics: High prevalence of dermatitis artefacta in children; multidisciplinary approach essential 2.
Elderly: Less commonly discussed but may present with similar psychogenic symptoms requiring psychiatric evaluation 3.
Comorbidities: Management should consider coexisting psychiatric conditions like depression and personality disorders 23.Key Recommendations
Establish a strong therapeutic alliance and provide psychological support to enhance patient engagement 1 (Evidence: Strong).
Utilize a multidisciplinary team including dermatologists and psychiatrists for comprehensive management of dermatitis artefacta 2 (Evidence: Moderate).
Consider psychotropic medications such as SSRIs and anxiolytics as adjunctive treatments when psychotherapy alone is insufficient 1 (Evidence: Moderate).References
