Abstract

Insights

Recent advancements in photodermatoses offer new insights into idiopathic conditions, photoallergens, porphyrias, and genodermatoses. This review provides crucial updates for managing these rare sun-sensitivity disorders.

Area of Science:

  • Dermatology
  • Photomedicine

Background:

  • Photodermatoses represent a diverse group of sun-induced skin conditions.
  • Recent literature reveals significant developments in understanding and managing these disorders.

Observation:

  • This review categorizes recent findings based on photodermatoses type: idiopathic, secondary to exogenous/endogenous agents (porphyrias), and genodermatoses.
  • Specific focus includes new disease presentations, characterization, and treatments for idiopathic photodermatoses.
  • Updates on photoallergens, clinical/diagnostic/treatment advances in porphyrias, and xeroderma pigmentosum complications are presented.

Findings:

  • New treatment strategies for idiopathic photodermatoses are emerging.
  • Clinical, diagnostic, and treatment updates for porphyrias are crucial.
  • Understanding neoplastic risks in genodermatoses like xeroderma pigmentosum is vital.

Implications:

  • This review offers up-to-date information for healthcare providers.
  • Enhanced identification and management of rare photodermatoses are facilitated.
  • Knowledge of photoprotection strategies is updated for clinical practice.

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...

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...

iPS Cell Differentiation01:22

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
