Skin Cancer01:30

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...

Renewal of Skin Epidermal Stem Cells

2.8K
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...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

19.4K
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,...

Papillary Dermis01:11

Papillary Dermis

5.1K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Area of Science:

  • Dermatology
  • Oncology

Background:

  • Basal cell carcinoma (BCC) diagnosis can be improved with dermoscopy.
  • Dermoscopic models for BCC diagnosis have evolved since the Menzies model.
  • Dermoscopic structures are classified as pigmented, vascular, or nonpigmented/nonvascular.

Purpose of the Study:

  • To review the role of dermoscopy in basal cell carcinoma diagnosis.
  • To highlight dermoscopy's utility in predicting BCC histologic subtypes.
  • To emphasize dermoscopy's value in early BCC detection and patient management.

Main Methods:

  • Review of existing literature on dermoscopy and basal cell carcinoma.
  • Classification of dermoscopic structures relevant to BCC.
  • Discussion of dermoscopy's application in differentiating BCC subtypes and predicting aggressiveness.

Main Results:

  • Dermoscopy enhances diagnostic accuracy for basal cell carcinoma.
  • Specific dermoscopic structures aid in classifying BCC subtypes (superficial vs. nonsuperficial).
  • Dermoscopy can help identify aggressive BCC variants and incipient lesions.

Conclusions:

  • Dermoscopy is a valuable noninvasive tool for BCC diagnosis and management.
  • Utilizing dermoscopy can lead to earlier detection and better prognosis for BCC patients.
  • Routine dermoscopic examination is beneficial for high-risk patients with a history of BCC or actinic damage.
