Summary
Dermal melanocytosis, including nevus of Ota and Mongolian spots, can indicate serious health risks like malignancy or metabolic disorders. Early diagnosis and specialist referral are crucial for managing these conditions.
Area of Science:
- Dermatology
- Pediatrics
- Genetics
Background:
- Dermal melanocytosis is common in newborns, causing parental concern.
- Four types exist: nevus of Ota, nevus of Ito, Mongolian spots, and dermal melanocyte hamartoma.
Purpose of the Study:
- Review of dermal melanocytosis entities.
- Emphasis on melanocyte biology.
- Highlighting associated systemic disorders, including malignancy and inborn errors of metabolism.
Main Methods:
- Literature review of clinical presentations and associated conditions.
- Analysis of recent findings on malignancy risks and metabolic associations.
- Evaluation of new therapeutic technologies.
Main Results:
- Nevus of Ota linked to increased risk of ocular, CNS, and cutaneous tumors.
- Nevus of Ito rarely associated with cutaneous melanoma.
- Extensive Mongolian spots may indicate inborn errors of metabolism (e.g., GM1 gangliosidosis).
- Q-switched alexandrite lasers show promise for cosmetic improvement.
Conclusions:
- Most cases resolve by toddler years without long-term risk.
- Some patients have underlying conditions requiring significant medical attention.
- Pediatric providers must recognize associated conditions and refer to dermatology when necessary.

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.

01:14Changes in Skin Color: Clinical Perspectives
4.2K
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.

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...

01:19Pigmentation
5.0K
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...

The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

11.2K
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,...
