Psychosis and psoriasis, the skin talks the truth

Abstract

Introduction

It is well known about relation between skin and mind, not only due to their mutual origin, but also by their illness expression parallelism. We report a case to show that reciprocity.

Personal antecedents

Woman, 42-year-old, single. She only suffers from a skin disease; mild psoriasis guttata placed in both elbows and knees. She treated it with local treatment (cortisone cream) during seasonal prutius and the lesions did not grow or expand. She was hospitalized due to psychotic symptoms (paranoid delusions with her colleagues) and started antipsychotics treatment (risperidone 12 mg per day and olanzapine 10 mg per night). By the same time, she suffered a psoriasis crisis. Her psoriatic plaques increased their sizes and her chest and both thighs were affected too. She complained about grave pruritus. All her medical test results were normal. After that, the patient improved her psychotics’ symptoms, but she started with agoraphobic signs and seclusion at home. Psoriasis were even worse than before and she needed metrotexate to treat it. Being introduced to escitalopram 15 mg per day, anxiety and depression symptoms disappeared and her grave psoriasis became the mild one that she knew.

Conclusion

Schizophrenia was associated with a greater variety of autoimmune diseases than was anticipated. Studies found evidence for a shared genetic etiology between schizophrenia and psoriasis. Despite that, we think that the study of psychopathology can amplify our understanding about the etiopathogenesis of psoriasis and associated mental disorders.
