Changes in Skin Color: Clinical Perspectives

2.0K
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...

Pigmentation01:19

Pigmentation

2.5K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Skin Cancer01:30

Skin Cancer

4.2K
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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

5.3K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Summary
This summary is machine-generated.

The Fitzpatrick skin phototype (FST) system poorly represents dark skin and is subjective. This review examines FST criticisms and alternatives to optimize skin phototype classification for better skin cancer risk assessment and treatment.

Area of Science:

  • Dermatology
  • Photobiology
  • Medical Classification Systems

Background:

  • Skin pigmentation and photosensitivity are crucial for assessing skin cancer risk and treatment response.
  • The widely used Fitzpatrick skin phototype (FST) system inadequately represents individuals with darker skin pigmentation.
  • The FST system is prone to misuse due to subjective assessments and unclear differentiation between pigmentation and photosensitivity.

Purpose of the Study:

  • To critically evaluate the existing literature on the Fitzpatrick skin phototype system.
  • To identify the limitations and criticisms associated with the FST system.
  • To explore and propose optimized alternatives for skin phototype classification.

Main Methods:

  • Comprehensive literature review of studies concerning the Fitzpatrick skin phototype system.
  • Analysis of criticisms regarding FST's representation of skin pigmentation and photosensitivity.
  • Evaluation of proposed alternative methods for skin type classification.

Main Results:

  • The FST system demonstrates significant underrepresentation of individuals with darkly pigmented skin.
  • Subjective assessment by patients and clinicians contributes to the misuse of the FST system.
  • The FST system fails to clearly distinguish between skin pigmentation and photosensitivity.

Conclusions:

  • Optimizing skin phototype classification is essential for accurate risk assessment and treatment planning.
  • Alternative classification systems are needed to better accommodate diverse skin pigmentation.
  • Improved methods are required to objectively differentiate pigmentation from photosensitivity in clinical practice.
