Summary
Canadian dermatologists continue to use the term dysplastic nevus. Most do not reexcise mild to moderate atypia lesions with positive margins.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Management of dysplastic nevi lacks consensus.
- No prior data existed on Canadian dermatologists' practices for these lesions.
Purpose of the Study:
- To survey Canadian dermatologists on their opinions regarding dysplastic nevus terminology and treatment.
- To establish prevailing practices among Canadian dermatologists for managing dysplastic nevi.
Main Methods:
- An online survey was distributed to 613 members of the Canadian Dermatology Association.
- The survey comprised 25 questions and was available in English and French.
Main Results:
- 179 dermatologists responded to the survey.
- A majority of respondents believe the term "dysplastic nevus" should be retained.
- Most participants reported never reexcising lesions with mild to moderate atypia, even with positive margins.
Conclusions:
- The term "dysplastic nevus" remains in common use among Canadian dermatologists.
- Canadian dermatologists generally do not reexcise dysplastic nevi with mild to moderate atypia if margins are positive.

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.

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.

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...

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.

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...
