Summary
Prurigo nodularis (PN) is a chronic inflammatory skin disease. Recent research has improved understanding of its natural history, pathophysiology, diagnosis, and treatment, highlighting PN as a unique condition.
Area of Science:
- Dermatology
- Immunology
- Pathophysiology
Background:
- Prurigo nodularis (PN) is a chronic, intensely itchy inflammatory skin condition.
- Historically, PN was poorly understood due to low prevalence and overlapping symptoms with other dermatoses.
- Recent years have seen increased research interest and therapeutic advancements.
Purpose of the Study:
- To review the evolution of understanding regarding Prurigo nodularis.
- To highlight recent advancements in the diagnosis and treatment of PN.
- To emphasize PN as a distinct disease entity with unique pathophysiology.
Main Methods:
- Literature review of historical and recent studies on Prurigo nodularis.
- Analysis of current research trends in PN pathophysiology and treatment.
- Synthesis of evolving medical understanding of PN.
Main Results:
- Understanding of PN's natural history and pathophysiology has significantly advanced.
- New therapeutic strategies are emerging, improving patient outcomes.
- PN is increasingly recognized as a unique disease entity.
Conclusions:
- The medical community's appreciation of Prurigo nodularis has grown substantially.
- Current research and therapeutic progress underscore PN's distinct characteristics.
- Further investigation into PN's unique pathophysiology is warranted.

01:11Papillary Dermis
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.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

01:15Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
