Insights

Actinic keratoses (AKs) are distinct skin lesions that can progress to squamous cell carcinomas. Recognizing their differences is crucial for effective treatment and understanding skin cancer development.

Area of Science:

  • Dermatology
  • Oncology
  • Carcinogenesis

Background:

  • Actinic keratoses (AKs) and squamous cell carcinomas (SCCs) represent a continuum in skin carcinogenesis.
  • These lesions typically develop on skin chronically exposed to sunlight.
  • Distinguishing AKs from SCCs is essential conceptually and for therapeutic planning.

Purpose of the Study:

  • To review the biological features underlying AK formation.
  • To highlight clinicopathologically distinctive aspects of AKs and SCCs.
  • To present recent findings on pharmacotherapies for these conditions.

Main Methods:

  • Review of biological features of AKs.
  • Analysis of clinicopathological differences between AKs and SCCs.
  • Survey of recent pharmacotherapy research.

Main Results:

  • Histological differences between AKs and SCCs are well-defined.
  • Pharmacotherapies discussed include anti-EGFR agents, imidazoquinolines, diclofenac-hyaluronan, and photodynamic therapy.

Conclusions:

  • Conceptual and therapeutic distinctions between AKs and SCCs should be maintained.
  • Emerging pharmacotherapies offer new treatment avenues for AKs and potentially SCCs.

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...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
