Insights

Most pigment nevi are harmless, but congenital and atypical nevi can indicate melanoma risk. Ultraviolet light exposure triggers nevus development, emphasizing the need for sun protection.

Area of Science:

  • Dermatology and Oncology
  • Cutaneous Biology

Context:

  • Pigmented nevi (moles) are common skin lesions, particularly in fair-skinned children.
  • Nevus development occurs primarily within the first two decades of life.
  • Both genetic predisposition and environmental factors, such as UV exposure, influence nevus formation.

Purpose:

  • To highlight the significance of pigment nevi as potential indicators of melanoma risk.
  • To emphasize the role of ultraviolet (UV) radiation in nevus onset.
  • To underscore the diagnostic challenges in differentiating nevi from melanoma.

Summary:

  • The majority of pigment nevi are benign, but congenital and atypical (dysplastic) nevi are recognized as melanoma precursors.
  • Individuals with numerous pigment nevi face an elevated lifetime risk of developing melanoma.
  • UV light is a key trigger for pigment nevus development, necessitating preventative measures.

Impact:

  • Informing the public and healthcare professionals about nevus-related melanoma risks.
  • Promoting awareness of the crucial role of sun protection in preventing nevus development.
  • Guiding dermatologists in the differential diagnosis of challenging pigmented skin lesions.

Pigmentation01:19

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...
Skin Cancer01:30

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...

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...
Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
