[Ethnic nail pigmentations and differential diagnoses]
Summary
Pigmentary nail changes, common in people of African descent, can stem from inflammation. Subungual melanoma is a critical diagnosis to exclude, requiring dermatoscopy or close clinical monitoring.
Area of Science:
- Dermatology
- Oncology
Background:
- Pigmentary nail changes present diverse etiologies, including chronic inflammation.
- These changes are more prevalent in individuals of African descent compared to Caucasians.
Observation:
- Subungual malignant melanoma represents a crucial differential diagnosis that must be excluded.
- Dermatoscopy can be a valuable diagnostic tool.
- In the absence of biopsy, regular clinical follow-ups are essential.
Findings:
- The study highlights the importance of considering melanoma in pigmentary nail changes.
- Early detection and monitoring are key for managing potential malignancy.
Implications:
- This underscores the need for heightened clinical vigilance in diagnosing nail pigmentation.
- Optimizing occupational skin protection is recommended for chronic paronychia management.

01:14Changes in Skin Color: Clinical Perspectives
4.1K
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.

01:19Pigmentation
4.9K
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...

01:05Accessory Structures of the Skin: Nails
4.0K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

6.5K
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...

01:22Photoreceptors and Visual Pathways
10.6K
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,...

01:39Epistasis
51.0K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
