Skin Cancer

3.0K
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...

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
  • Oncology

Background:

  • Acral lentiginous melanoma (ALM) is a rare, aggressive subtype of cutaneous malignant melanoma.
  • Unlike other melanomas, ALM is not associated with UV radiation exposure.
  • It presents a poor survival prognosis and unique clinical characteristics.

Purpose of the Study:

  • To review the current understanding of acral lentiginous melanoma.
  • To highlight diagnostic challenges and barriers to timely diagnosis.
  • To discuss potential strategies for improving patient outcomes.

Main Methods:

  • Comprehensive literature review focusing on ALM.
  • Analysis of incidence, diagnostic criteria, and histopathology.
  • Evaluation of dermatoscopic and reflectance confocal microscopy features.
  • Review of genomic alterations and current treatment modalities.
  • Inclusion of recent case reports illustrating diagnostic difficulties.

Main Results:

  • ALM occurs in acral locations (palms, soles, subungual areas).
  • Diagnostic challenges and delays are frequently encountered.
  • Genomic alterations and treatment options are areas of ongoing research.

Conclusions:

  • Increased patient and healthcare provider education is vital for early detection.
  • Development of novel, targeted therapeutics is critical.
  • Prompt and accurate diagnosis is essential for improving ALM outcomes.
