Accessory Structures of the Skin: Nails

4.0K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Changes in Skin Color: Clinical Perspectives

4.1K
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...

Skin Diseases and Disorders

6.0K
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...

Skin Cancer01:30

Skin Cancer

6.5K
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Papillary Dermis

6.6K
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...

Summary

Nail abnormalities are common in vitiligo patients, with over 78% showing changes like longitudinal ridging and leukonychia. This highlights the importance of examining nails in vitiligo diagnosis and management.

Area of Science:

  • Dermatology
  • Clinical Research
  • Nail Disorders

Background:

  • Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the population.
  • Nail abnormalities are sometimes seen in autoimmune diseases like psoriasis and alopecia areata.
  • Previous suggestions indicate potential nail changes in vitiligo patients.

Purpose of the Study:

  • To determine the frequency and clinical presentation of nail abnormalities in vitiligo patients.
  • To compare nail abnormalities in vitiligo patients versus healthy controls.
  • To investigate correlations between nail abnormalities and clinical parameters in vitiligo.

Main Methods:

  • A study involving 100 vitiligo patients and 100 healthy controls.
  • Collection of comprehensive medical histories and thorough general and nail examinations.
  • Documentation of all observed nail changes, with mycological investigations for suspected fungal infections.

Main Results:

  • Nail abnormalities were significantly more prevalent in vitiligo patients (78%) compared to controls (55%).
  • Longitudinal ridging (42%) was the most frequent abnormality, followed by leukonychia, absent lunula, onycholysis, and nail bed pallor.
  • The occurrence of longitudinal ridging was notably higher in the vitiligo group.

Conclusions:

  • Nail abnormalities are more common in individuals with vitiligo.
  • Systematic nail examination is valuable for vitiligo patients due to the high frequency of nail changes.
  • Further research is needed to understand the underlying causes of these nail abnormalities in vitiligo.
