Skin Cancer01:30

Skin Cancer

5.2K
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...

Skin Diseases and Disorders

5.4K
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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Cellular Adaptation IV: Dysplasia and Metaplasia

49
DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...

Papillary Dermis01:11

Papillary Dermis

5.8K
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...

Reticular Dermis01:15

Reticular Dermis

4.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

44
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...

Summary
This summary is machine-generated.

Epidermodysplasia verruciformis (EV) is a rare skin disorder linked to specific human papillomavirus (HPV) types. Genetic mutations in TMC6 or TMC8 genes increase cancer risk, particularly squamous cell carcinoma (SCC), in sun-exposed areas.

Area of Science:

  • Genetics
  • Dermatology
  • Virology

Background:

  • Epidermodysplasia verruciformis (EV) is a rare genodermatosis.
  • It causes susceptibility to specific human papillomavirus (HPV) infections.
  • This leads to EV-typical plane warts and increased risk of cutaneous malignancies, especially squamous cell carcinoma (SCC).

Purpose of the Study:

  • To understand the link between genetic mutations and viral oncogenesis in EV.
  • To explore the role of TMC6 and TMC8 gene mutations in HPV susceptibility.
  • To investigate the pathogenesis of EV and its implications for understanding viral carcinogenesis.

Main Methods:

  • The study focuses on analyzing the genetic basis of EV, specifically mutations in TMC6 and TMC8 genes.
  • It examines the correlation between these mutations, HPV infection, and the development of cutaneous malignancies.
  • The research utilizes the EV model to understand viral oncogenesis applicable to the general population.

Main Results:

  • Mutations in transmembrane channel genes TMC6 or TMC8 predispose individuals to HPV infection and EV.
  • Affected individuals face a lifelong increased risk of cutaneous malignancy, particularly SCC, in UV-exposed areas.
  • EV is a key model for understanding the correlation between cancer and viral infection.

Conclusions:

  • EV serves as a cornerstone in understanding viral oncogenesis.
  • TMC mutations are suggested to impair patient immunity, promoting specific HPV type amplification.
  • Further research is needed to fully elucidate the pathogenesis of Epidermodysplasia verruciformis.
