Pigmentation

Pigmentation

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...

Changes in Skin Color: Clinical Perspectives

Changes 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...

Skin Cancer

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

Skin Diseases and Disorders

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...

Introduction to the Integumentary System

Introduction to the Integumentary System

The integumentary system is the organ system that comprises the skin and its associated structures. It is the largest system in the human body and plays a crucial role in protecting and maintaining homeostasis. The integumentary system serves several functions including protection, regulation, sensation, and secretion.
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

Summary

Diagnosing skin conditions in patients with skin of color requires specialized knowledge due to differences in melanin and presentation. Early skin cancer screening and sun protection are crucial for this population.

Area of Science:

Dermatology
Pigmentation Biology
Medical Education

Background:

Physicians require enhanced experience for accurate diagnosis of skin diseases in individuals with skin of color.
Skin of color exhibits distinct differences in melanin structure, content, and distribution compared to lighter skin types.

Purpose of the Study:

To review current knowledge on dermatological conditions affecting skin of color.
To highlight diagnostic and therapeutic challenges in dermatology for diverse skin pigmentation.

Main Methods:

A narrative review of scientific articles and book chapters.
Inclusion of comparative studies across different skin pigmentation types and ethnic groups.
Literature search included publications up to 2026.

Main Results:

Skin of color presents unique challenges, including distinguishing malignancy from hyperpigmentation and recognizing inflammatory conditions where erythema may be less visible.
Squamous-cell carcinoma is more frequent in darker skin, and malignant melanoma, though less common, is often diagnosed at later stages.
Inflammatory skin diseases show altered presentations, and sequelae like post-inflammatory hyper/hypopigmentation and scarring are common and distressing.

Conclusions:

Limited research exists on skin of color, necessitating inclusive evaluation of dermatological findings.
Dermatological education must adapt to better serve patients with skin of color.
Screening for skin cancer and advising on ultraviolet light protection are essential for individuals with skin of color.
