Summary
Melanoma incidence is rising, particularly in white populations. This study reveals higher mortality and advanced stage at diagnosis for melanoma in minority groups, highlighting a critical public health concern.
Area of Science:
- Dermatology and Public Health
- Epidemiology of Cutaneous Malignancies
Background:
- Melanoma incidence is increasing in white populations, with limited data on minority groups.
- Investigating melanoma incidence, presentation, and survival across diverse racial and ethnic groups is crucial.
Purpose of the Study:
- To analyze melanoma incidence, clinical characteristics, and survival rates among different racial and ethnic populations.
- To identify disparities in melanoma diagnosis and outcomes based on race/ethnicity.
Main Methods:
- Utilized Surveillance, Epidemiology, and End Results (SEER) data from 1992-2002.
- Conducted multivariate and Cox proportional hazards analyses to assess race/ethnicity's impact on clinicopathologic factors and survival.
Main Results:
- Melanoma incidence per 100,000 was highest in whites (18.4) compared to minorities (2.3-1.0).
- Minority populations showed higher rates of lower extremity and acral lentiginous melanomas.
- Minorities experienced significantly lower 5-year survival (72.2%-81.1%) versus whites (89.6%) and a 1.96- to 3.01-fold increased mortality risk.
- Minorities were more likely to be diagnosed with stage IV melanoma (ORs 2.4-4.2) compared to whites.
Conclusions:
- Melanoma poses a significant public health challenge across all ethnic groups.
- Disparities in melanoma survival are linked to differences in disease stage at presentation.
- Further understanding of melanoma in minority populations can facilitate early detection and improve outcomes.

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.

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...

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...
