Summary
This review details rare psoriasis variants, aiding diagnosis and management. Recognizing atypical psoriasis forms is crucial for accurate treatment and avoiding misdiagnosis.
Area of Science:
- Dermatology
- Immunology
Background:
- Psoriasis is a heterogeneous, immune-mediated inflammatory skin disease.
- Plaque psoriasis is common, but atypical variants present diagnostic challenges due to unusual presentations.
Purpose of the Study:
- To review current evidence on selected atypical psoriasis variants.
- To guide recognition, diagnosis, and management of rare psoriasis forms.
Main Methods:
- Narrative review of existing literature.
- Discussion of epidemiology, clinical presentation, dermoscopy, histopathology, differential diagnosis, and treatment for specific variants.
Main Results:
- Summarizes evidence for psoriasis gyrata, linear psoriasis, follicular psoriasis, and others.
- Highlights the importance of distinguishing these from mimickers like infections or neoplasms.
Conclusions:
- Awareness of uncommon psoriasis variants improves diagnostic accuracy.
- Integrating clinical, dermoscopic, and histopathological findings is key for challenging cases.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

01:21EPS and iPS Cells in Disease Research
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
