Insights

Idiopathic prurigo nodularis Hyde, a skin condition, often originates from hair follicles. Histological analysis of biopsies revealed hair follicles in the majority of prurigo lesions studied.

Area of Science:

  • Dermatology
  • Pathology
  • Histology

Background:

  • Idiopathic prurigo nodularis Hyde is a chronic, intensely itchy skin condition.
  • The exact etiology of prurigo nodularis remains unclear, with various factors proposed.
  • Previous research has not definitively established a consistent link to specific anatomical structures.

Purpose of the Study:

  • To investigate the potential association between hair follicles and the development of idiopathic prurigo nodularis Hyde.
  • To analyze the histological features of prurigo lesions in patients without insect bites or other underlying diseases.

Main Methods:

  • Histological examination of 38 prurigo nodularis biopsies from 17 patients.
  • Serial sectioning to determine the presence and location of hair follicles within lesions.
  • Evaluation of epidermal and dermal changes, including acanthosis, spongiosis, and dermal infiltrates.

Main Results:

  • Hair follicles were identified in the center of 88% of smaller nodules and 55% of larger nodules.
  • Epidermal changes such as acanthosis and spongiosis were observed.
  • Dermal infiltrates were noted around the involved hair follicles in a triangular pattern.

Conclusions:

  • Idiopathic prurigo nodularis Hyde appears to be frequently associated with hair follicles.
  • Hair follicles may play a significant role in the pathogenesis of this condition.
  • Further research is warranted to elucidate the precise mechanism of hair follicle involvement.

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Papillary 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...

Accessory 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...

Accessory Structures of the Skin: Sebaceous Glands

A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Skin 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...
Folliculogenesis01:20

Folliculogenesis

Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...
