Summary
A young woman had widespread skin lesions since birth, diagnosed as systematised epidermal nevus. Treatment with carbon dioxide laser was recommended, with monitoring for neurological issues.
Area of Science:
- Dermatology
- Genetics
- Pathology
Background:
- Epidermal nevi are benign congenital skin tumors.
- Systematised epidermal nevus presents as widespread lesions following Blaschko's lines.
- Epidermal nevus syndrome involves epidermal nevi with extracutaneous abnormalities.
Observation:
- A 20-year-old female presented with congenital, widespread, raised skin lesions.
- Lesions included pigmented macules and hyperkeratotic papules distributed along Blaschko's lines.
- Histopathology showed hyperkeratosis, acanthosis, and basal layer pigmentation.
Findings:
- The patient was diagnosed with systematised epidermal nevus without features of epidermal nevus syndrome.
- Systemic examination revealed no extracutaneous abnormalities.
- The diagnosis was confirmed via clinical and histopathological evaluation.
Implications:
- Carbon dioxide laser therapy is a potential treatment for cosmetic improvement.
- Long-term surveillance for potential late-onset neurological symptoms is advised.
- This case highlights the importance of differentiating systematised epidermal nevus from epidermal nevus syndrome.

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.

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...

01:19Clinical Applications of Epidermal Stem Cells
3.4K
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...

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...

01:24Cells of the Epidermis
9.1K
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

01:12Renewal of Skin Epidermal Stem Cells
3.3K
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...
