Changes in Skin Color: Clinical Perspectives01:14

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

Pigmentation01:19

Pigmentation

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...

Skin Diseases and Disorders

6.2K
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...

Skin Cancer01:30

Skin Cancer

6.6K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

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,...

Pleiotropy01:33

Pleiotropy

44.2K
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,...

Purpose of the Study:

  • To provide an in-depth analysis of pigmentary disorders in SOC.
  • To emphasize clinical manifestations, histopathologic features, and pathophysiologic mechanisms.
  • To highlight pigmentary mimics and their associations.

Main Methods:

  • Comprehensive literature review.
  • Analysis of clinical and histopathologic features.
  • Discussion of pathophysiologic mechanisms.

Main Results:

  • Detailed characterization of pigmentary disorders in SOC.
  • Identification of mimics and associated conditions.
  • Emphasis on histopathologic precision for diagnosis.

Conclusions:

  • Accurate diagnosis of pigmentary disorders in SOC is crucial.
  • Histopathologic characterization improves diagnostic precision.
  • Patient-centered care is supported by a thorough understanding of these conditions.
