Changes in Skin Color: Clinical Perspectives01:14

Changes 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.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Cancer01:30

Skin Cancer

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...

Pigmentation01:19

Pigmentation

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...

Pleiotropy01:33

Pleiotropy

43.9K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Epistasis01:39

Epistasis

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...

Area of Science:

  • Neurocutaneous disorders
  • Pediatric neurology
  • Genodermatoses

Background:

  • Ito hypomelanosis is a rare neurocutaneous disorder characterized by hypopigmented macules.
  • It is often associated with neurological abnormalities, presenting a diagnostic challenge.

Observation:

  • Four infants aged 8-20 months presented with epilepsy, psychomotor delay, and diffuse hypomelanosis.
  • Electroencephalograms revealed diffuse irritative abnormalities.
  • Brain imaging was normal in two cases and showed hemispheric atrophy in one.

Findings:

  • All infants exhibited drug-resistant epilepsy and persistent psychomotor delay.
  • No significant improvement was observed despite antiepileptic treatment and physical therapy.
  • The neurocutaneous and neurological manifestations appear to follow a severe, unremitting course.

Implications:

  • This case series underscores the severity of Ito hypomelanosis and its profound impact on neurodevelopment.
  • Early recognition and multidisciplinary management are crucial for affected infants.
  • Further research into the underlying pathophysiology and potential therapeutic targets is warranted.
