Objective: Psychogenic factors may play a contributory role in the development or persistence of lichen simplex chronicus (LSC). The objective of this study was to evaluate the psychiatric profile of patients with LSC including depression and dissociative experiences.
Method: Dermatology outpatients with a LSC (n=30) were compared with outpatients with tinea in which psychological factors are regarded as negligible (n=30). All subjects were given psychiatric scales including the Symptom Checklist-90-Revised (SCL-90-R), Hamilton Rating Scale for Depression (HAM-D) and Dissociative Experience Scale (DES).
Results: All mean SCL-90 scores for general psychopathology were higher in the LSC compared to the control group. HAM-D and DES scores were significantly higher in the LSC group (P<.05) as well. In addition, the number of patients whose total DES score of 30 and above was higher in the LSC group.
Conclusions: Psychiatric symptoms appear relatively common among patients with LSC. Further research is needed to confirm the possible role of dissociative tendencies in the etiology of LSC.
