[Tumor characteristics of keloid]
1Department of Burns and Plastic ＆ Wound Repair Surgery, Xiang'an Hospital of Xiamen University, Xiamen 361102, China.
Summary
Keloids exhibit tumor-like behaviors, growing beyond wounds and recurring after treatment. Understanding these tumor characteristics is crucial for effective keloid management beyond traditional scar perspectives.
Area of Science:
- Dermatology
- Oncology
- Pathogenesis of skin conditions
Background:
- Keloids display distinct clinical behaviors compared to hypertrophic scars.
- These behaviors include exceeding wound margins, invading surrounding skin, and high recurrence rates post-treatment.
- Current understanding may be insufficient, necessitating a re-evaluation of keloid pathogenesis.
Purpose of the Study:
- To re-evaluate the pathogenesis of keloid formation.
- To describe keloid characteristics from a tumor biology perspective.
- To identify key tumor-like features contributing to keloid development.
Main Methods:
- Comparative clinical observation of keloid and hypertrophic scar characteristics.
- Literature review and analysis of keloid behavior through the lens of tumor biology.
- Identification and summarization of specific tumor-associated traits in keloids.
Main Results:
- Keloids demonstrate uncontrolled growth beyond initial wound boundaries.
- Keloids exhibit resistance to apoptosis, contributing to their persistence.
- Abnormal angiogenesis is a significant factor in keloid development and progression.
Conclusions:
- Keloids possess distinct tumor-like characteristics.
- Viewing keloids solely as scars is inadequate for understanding their behavior.
- Further research into keloid tumor biology is warranted for improved therapeutic strategies.

01:30Skin Cancer
5.1K
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.

02:17The Tumor Microenvironment
7.2K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

02:18Cancer
51.5K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

02:07Tumor Progression
6.8K
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...

02:23Abnormal Proliferation
4.8K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
