Skin Cancer

5.4K
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

3.9K
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...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Skin Diseases and Disorders

4.9K
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...

Area of Science:

  • Dermatology
  • Photobiology
  • Toxicology

Background:

  • Phytophotodermatitis is a skin reaction triggered by plant-derived furocoumarins and ultraviolet A (UVA) light exposure.
  • Psoralen, a prevalent phototoxic furocoumarin, is found in numerous plant species, leading to varied clinical presentations.

Purpose of the Study:

  • To provide a comprehensive overview of the diagnosis and management of psoralen-induced phytophotodermatitis.
  • To explore other clinical applications of psoralen and related compounds.

Main Methods:

  • Literature review of phytophotodermatitis, focusing on psoralen.
  • Analysis of diagnostic criteria and current treatment strategies.
  • Review of existing and potential clinical uses of furocoumarins.

Main Results:

  • Phytophotodermatitis diagnosis relies on clinical presentation and exposure history.
  • Management involves avoiding causative agents, photoprotection, and symptomatic treatment.
  • Psoralen's phototoxicity has therapeutic applications, such as in PUVA therapy.

Conclusions:

  • Effective management of psoralen-induced phytophotodermatitis requires accurate diagnosis and avoidance of triggers.
  • Understanding psoralen's photobiological properties is crucial for both therapeutic and preventative strategies.
  • Further research can optimize clinical applications and patient outcomes.
