Skin Cancer01:30

Skin Cancer

6.6K
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...

Cells of the Epidermis01:24

Cells of the Epidermis

9.0K
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...

Clinical 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...

Papillary Dermis01:11

Papillary Dermis

6.8K
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...

Summary

Actinic granuloma and annular elastolytic giant cell granuloma are distinct skin conditions featuring elastolysis and giant cells. Histopathology is key to differentiating them from similar conditions like granuloma annulare.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Actinic granuloma and annular elastolytic giant cell granuloma describe skin conditions with elastolysis, elastophagocytosis, and multinucleated giant cells.
  • Clinical presentation ranges from papules to annular plaques, potentially mimicking granuloma annulare.

Purpose of the Study:

  • To differentiate actinic granuloma and annular elastolytic giant cell granuloma from granuloma annulare.
  • To understand the pathogenesis and clinical course of these elastolytic conditions.

Main Methods:

  • Histopathologic examination to identify key features like elastolysis and giant cell infiltrate.
  • Clinical assessment of skin lesions.

Main Results:

  • Histopathology confirms elastolysis, elastophagocytosis, and multinucleated giant cells as characteristic findings.
  • Distinct histopathologic features allow differentiation from granuloma annulare despite some clinical similarities.

Conclusions:

  • Actinic granuloma and annular elastolytic giant cell granuloma are distinct entities characterized by specific histopathologic findings.
  • The conditions result from immune responses affecting elastic tissue, often associated with diabetes mellitus.
  • Management involves addressing chronic inflammation with variable treatment responses and potential for spontaneous remission.
