Decreased Body Temperature01:29

Decreased Body Temperature

890
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Accessory Structures of the Skin: Hair Growth and Types

2.2K
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: Hair and Hair Follicles

4.0K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

4.1K
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...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

2.7K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Folliculogenesis01:20

Folliculogenesis

1.8K
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...

Summary

This review simplifies scalp biopsy interpretation for pathologists, focusing on horizontal sectioning for nonscarring alopecia. It aids in diagnosing common scarring and nonscarring hair loss conditions.

Area of Science:

  • Dermatopathology
  • Histopathology
  • Trichology

Background:

  • Scalp biopsies are crucial for diagnosing hair loss disorders.
  • Pathologists may find interpreting scalp biopsies, particularly with horizontal sectioning for nonscarring alopecia, challenging.
  • Accurate diagnosis requires correlating histological findings with clinical presentation.

Purpose of the Study:

  • To provide a guide on interpreting scalp biopsies.
  • To discuss the principles of histological analysis of the scalp.
  • To review common forms of scarring and nonscarring alopecia.

Main Methods:

  • Review of existing literature on scalp biopsy interpretation.
  • Discussion of fundamental principles in histopathology of the scalp.
Keywords:
Horizontal sectionsMost common forms of alopeciaNon-scarring alopeciaScarring alopecia
