Skin Cancer01:30

Skin Cancer

6.4K
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...

Pigmentation01:19

Pigmentation

4.8K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Papillary Dermis01:11

Papillary Dermis

6.5K
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...

Tumor Progression02:07

Tumor Progression

7.7K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Summary
This summary is machine-generated.

Older age and lower education correlate with late melanoma detection. Skin self-examination is key for early diagnosis, especially for those over 50 unaware of their risk.

Area of Science:

  • Dermatology
  • Epidemiology
  • Public Health

Background:

  • Cutaneous melanoma incidence is rising globally, with similar trends in Tuscany, Italy.
  • While thin melanomas are prevalent, thick melanomas are also increasing, necessitating strategies to reduce mortality.
  • This study aimed to identify characteristics differentiating thin and thick melanomas to tailor prevention efforts.

Purpose of the Study:

  • To compare thin and thick melanoma cases in Tuscany using a case-case study design.
  • To identify personal and tumor characteristics associated with melanoma thickness.
  • To inform customized preventive interventions for cutaneous melanoma.

Main Methods:

  • A case-case study involving nine melanoma diagnostic centers in Tuscany.
  • Inclusion of consecutive invasive melanomas diagnosed between July 2010 and December 2011.
  • Matching of one thick melanoma (≥1 mm) to two thin melanomas, with data collection via questionnaires on sun exposure, detection, and prevention awareness.

Main Results:

  • Older age and lower education levels are linked to delayed melanoma detection.
  • Regular skin self-examination significantly aids in the early diagnosis of thick melanomas.
  • Individuals over 50 with limited nevi, sun exposure, and sunburn history may be at higher risk for late diagnosis, potentially due to a lack of perceived risk.

Conclusions:

  • A new strategy is needed to improve early skin melanoma diagnosis rates.
  • Educational campaigns should be re-evaluated to ensure they reach at-risk populations effectively.
  • Increased involvement of general practitioners is recommended to enhance melanoma detection and prevention efforts.
