Ulcers appear after the scar is broken

Introduction In the early stage of scar cancer, there is an ulcer after the scar is damaged, or it is gradually enlarged and collapsed by the small papules, and it is on the edge of the ulcer that has not healed for a long time. Cicatricial carcinoma is a skin cancer formed by carcinogenesis of skin scars or keloids caused by various causes. Scar cancer is based on the formation of scars or keloids. It is a few years old, and it develops gradually over a period of several decades. It is often scratched due to the itching of scars, and the scars are damaged and eroded by friction, resulting in long-lasting healing. The ulcer is malignant.

Cause

Cicatricial carcinoma is a skin cancer formed by carcinogenesis of skin scars or keloids caused by various causes. Scar cancer is based on the formation of scars or keloids. It is a few years old, and it develops gradually over a period of several decades. It is often scratched due to the itching of scars, and the scars are damaged and eroded by friction, resulting in long-lasting healing. The ulcer is malignant. French MarjoIin first described the characteristics of malignant ulcers in 1828, and later scholars referred to scar cancer as MarjoIin ulcer. Scar cancer is more common in burn scars, more men than women, more than less old, better in the limbs.

an examination

Pathological scar cancer is mostly squamous cell carcinoma, and a small part is basal cell carcinoma. Generally, the disease develops slowly. At the beginning, there is an ulcer after the scar is damaged, or it is gradually enlarged and collapsed by the small papules, and it is on the edge of the ulcer that has not healed for a long time. Gradually bulging, for keratinized proliferation and papillary hyperplasia. Most of the squamous cell carcinomas are cancer cells with more complete differentiation, and some form keratinized cancer beads. Since cancer cells are surrounded by the base and the surrounding tough and dense scar tissue, diffusion and transfer are generally less likely to occur. Sometimes ulcers have malignant cancer, while other parts are still chronic inflammation and granulation tissue. However, if the cancer cells expand to normal tissues, they spread rapidly and metastasize, and the lymph nodes in the area near the cancer are swollen. Scar cancer is rarely seen in blood transfer.

Differential diagnosis

Scar atrophy: Atrophic scar is a scar named after the dysfunction caused by it.

Contracture scar: A scar named after the dysfunction caused by it. More common after deep burn healing, due to scar contraction, often lead to shape changes and dysfunction, long-term scar contracture can affect the development of bones, muscles, blood vessels, nerves and other tissues, should be treated early.

Superficial scar: refers to a scar on the superficial layer of the skin, which is slightly different from normal skin and forms a skin infection.
