Marjolin's ulcer refers to an aggressive ulcerating squamous cell carcinoma presenting in an area of previously traumatized, [1] chronically inflamed, [2] or scarred skin. [3]: 737 [4] They are commonly present in the context of chronic wounds including burn injuries, varicose veins, venous ulcers, [5] ulcers from osteomyelitis, [6] and post radiotherapy scars.
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
This way the radiation source can be applied to complex locations and minimize radiation to healthy tissue. [57] After removal of the cancer, closure of the skin for patients with a decreased amount of skin laxity involves a split-thickness skin graft. A donor site is chosen and enough skin is removed so that the donor site can heal on its own.
Infiltrative or morpheaform basal-cell cancers can present as a skin thickening or scar tissue – making diagnosis difficult without using tactile sensation and a skin biopsy. It is often difficult to visually distinguish basal-cell cancer from acne scar, actinic elastosis, and recent cryodestruction inflammation. [14]
[17] [21] Though brain tissue contains no pain sensors, brain tumors can cause pain by pressing on blood vessels or the membrane that encapsulates the brain (the meninges), or indirectly by causing a build-up of fluid that may compress pain-sensitive tissue. [22] Pain from cancer of the organs, such as the stomach or liver (visceral pain), is ...
Accumulation of these cancer cells causes a microscopic focus of abnormal cells that are, at least initially, locally confined within the specific tissue in which the progenitor cell resided. This condition is called squamous-cell carcinoma in situ , and it is diagnosed when the tumor has not yet penetrated the basement membrane or other ...
The stromal reaction in cancer is similar to the stromal reaction induced by injury or wound repair: increased extracellular matrix (ECM) and growth factor production and secretion, which consequently cause growth of the tissue. [10] In other words, the body reacts similarly to a cancer as it does to a wound, causing scar-like tissue to be ...
Adhesions form as a natural part of the body's healing process after surgery in a similar way that a scar forms. The term "adhesion" is applied when the scar extends from within one tissue across to another, usually across a virtual space such as the peritoneal cavity. Adhesion formation post-surgery typically occurs when two injured surfaces ...
