Is a rodent ulcer malignant?

Rodent ulcers are a type of skin cancer. Also known as basal cell carcinoma, rodent ulcers occur in the lower most layer of your skin. They usually develop in skin areas exposed to the sun. Rodent ulcers are a very slow growing cancer that usually does not spread to other parts of your body.

What is marjolin’s ulcer?

Introduction. A Marjolin ulcer is a cutaneous malignancy that arises in the setting of previously injured skin, longstanding scars, and chronic wounds. Historically, Marjolin ulcers are named for French surgeon Jean Nicolas Marjolin and first described as ulcerations with dense villi arising within a burn cicatrix.

What is ulcerated squamous cell carcinoma?

Ulcerating squamous cell carcinoma (SCC) is a common non-melanotic skin cancer, second in frequency only to basal cell carcinoma (BCC). It occurs as the result of malignant transformation of epidermal keratinocytes, invades local tissues and has the potential to metastasize.

What are the distinguishing characteristics of squamous cell carcinoma?

SCCs can appear as scaly red patches, open sores, rough, thickened or wart-like skin, or raised growths with a central depression. At times, SCCs may crust over, itch or bleed. The lesions most commonly arise in sun-exposed areas of the body.

Can a scar become cancerous?

The scar tissue carcinoma is a rare disease which arises from the floor of unstable scars, chronic fistulae, ulcera and radiation injuries.

What is the difference between melanoma and melanoma ulceration?

The thicker the melanoma measures, the greater its chance of spreading. Tumor ulceration: Ulceration is a breakdown of the skin on top of the melanoma. Melanomas with ulceration are more serious because they have a greater risk of spreading, so they are staged higher than tumors without ulceration.

What is Breslow measurement of melanoma?

Tumor thickness: The thickness of the melanoma is called the Breslow measurement. In general, melanomas less than 1 millimeter (mm) thick (about 1/25 of an inch) have a very small chance of spreading. As the melanoma becomes thicker, it has a greater chance of spreading. Ulceration: Ulceration is a breakdown of the skin over the melanoma.

What is considered a high-risk melanoma?

Localized but larger tumors may have other traits such as ulceration that put them at high risk of spreading. Stage II: Intermediate, high-risk melanomas are tumors deeper than 1 mm that may or may not be ulcerated.
