Abstract:
Inverse psoriasis is clinically defined by chronic inflammatory lesions in intertrigineous areas. Colonisation or infection with Candida ssp. or bacteria is common. The disease-related quality of life is significantly reduced especially regarding sexual behavior. After the exclusion of relevant differential diagnoses, therapy should be adapted to the clinical outcome and potential comorbidities. Substances which are efficacious in psoriasis vulgaris are generally efficacious in inverse psoriasis, but have to be used off-label. Controlled clinical studies are only available for topical ascomycin.
Insights
Inverse psoriasis causes chronic skin inflammation in folds, often with infections. Treatments effective for general psoriasis can be used off-label, improving quality of life.
Area of Science:
- Dermatology
- Immunology
Background:
- Inverse psoriasis presents as chronic inflammatory lesions in skin folds.
- Secondary infections with Candida or bacteria are common in inverse psoriasis.
- Reduced quality of life, particularly sexual function, is a significant issue.
Purpose of the Study:
- To review the clinical presentation and management of inverse psoriasis.
- To highlight the need for tailored therapy based on clinical outcomes and comorbidities.
- To discuss treatment options, including off-label use of psoriasis vulgaris therapies.
Main Methods:
- Literature review of clinical studies and therapeutic guidelines for inverse psoriasis.
- Analysis of treatment efficacy and safety data.
- Discussion of differential diagnoses and management strategies.
Main Results:
- Substances effective for psoriasis vulgaris are generally effective for inverse psoriasis but often require off-label use.
- Topical ascomycin is one of the few agents with controlled clinical study data for inverse psoriasis.
- Therapeutic approaches must consider comorbidities and clinical response.
Conclusions:
- Effective management of inverse psoriasis requires careful diagnosis and individualized treatment plans.
- Off-label use of established psoriasis treatments is often necessary.
- Further controlled studies are needed to optimize therapeutic strategies for inverse psoriasis.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
