Psychological disorders in patients with lichen simplex chronicus: A comparative study with normal population

Abstract

Abstract Introduction Lichen simplex chronicus (LSC) is an eczematous skin disease characterized by single or a few thickened and ‘lichenified’ skin plaques, with very disturbing itching. The role of psychological factors and transient relief of pruritus after violent scratching seems to be of great importance in development and perpetuation of its course. On the other hand, the chronic nuisance itching may lead to burdensome psychological distress and impaired quality of life. Aim This study sought to elucidate more aspects of this interplay. Material and methods 40 patients with LSC (diagnosed clinically) and 40 healthy controls (selected between attendants of the patients with no skin problem) were enrolled in this study. Hamilton questionnaire and symptom checklist 90-revised (SCL-90 R) were filled by a psychologist for all cases. Demographic characteristics, localization of the skin lesions, personal and family history of psychiatric disorders (if existent) were recorded. Results and discussion Mean scores of SCL-90-R in somatization, interpersonal sensitivity, depression, anxiety, aggression, and phobia items were significantly higher in patient group than control group. Regarding Hamilton depression test, the mean scores were higher in patient group, but the difference was not statically significant. Conclusions Patients with LSC are subject to ample psychiatric morbidities. Close collaboration of dermatologist and psychiatrist is essential in its successful control.
