Malignant melanoma

Melanoma, also redundantly known as malignant melanoma, is a type of skin cancer that develops from the pigment-producing cells known as melanocytes. Melanomas typically occur in the skin but may rarely occur in the mouth, intestines or eye (uveal melanoma).In women, they most commonly occur on the legs, while in men they most commonly occur on the back Melanoma. Melanoma is a form of skin cancer that begins in the cells (melanocytes) that control the pigment in your skin. This illustration shows melanoma cells extending from the surface of the skin into the deeper skin layers. Melanoma, the most serious type of skin cancer, develops in the cells (melanocytes) that produce melanin — the pigment.

Definition. Malignant melanoma is a type of cancer arising from the melanocyte cells of the skin. Melanocytes are cells in the skin that produce a pigment called melanin.

Melanoma is a malignant tumor of melanocytes, which are the cells that make the pigment melanin and are derived from the neural crest. Although most melanomas arise in the skin, they may also arise from mucosal surfaces or at other sites to which neural crest cells migrate, including the uveal tract Melanomas are a major cause of premature death from cancer. The gradual decrease in rates of morbidity and mortality has occurred as a result of public health campaigns and improved rates of early diagnosis. Survival of melanoma has increased to over 90%. Management of melanoma involves a number of components: excision, tumor staging, re-excision with negative margins, adjuvant therapies. Melanoma in its earliest stages is often treated by surgery to remove the melanoma and a portion of skin surrounding it, according to the ACS. If the cancer has already progressed to a more.

Background . Gynecologic melanomas are extremely rare malignancies, and primary malignant melanoma of the cervix (PMMC) is the rarest among them all, with less than 100 cases reported so far. Although some conditions have been correlated with the pathogenesis of this entity, no specific risk factor has been yet identified, with vaginal bleeding being the most common symptoms Malignant melanoma is a potentially lethal melanocytic neoplasm with a propensity for distant metastasis. Lesions may arise de novo, or within dysplastic, congenital, or banal nevi. 7-10 Early detection and definitive therapy are necessary to minimize the risk of metastatic disease. Melanoma may be virtually preventable with simple behavioral changes Malignant melanoma is the most serious form of skin cancer, however it is often treatable with surgery alone if detected early enough. Rates of malignant melanoma are on the rise in the UK, so it's important to have any unusual moles or skin changes checked by a specialist as soon as possible 17. Persistent growth of residual, incompletely excised primary malignant melanoma, of either the epidermal or the invasive component, or both Persistence or recurrence of a flat variably pigmented patch adjacent to or surrounding the scar of the primary excision site. DD - Metastatic melanoma involving scar Pigmented basal cell carcinoma Malignant melanoma is not a common cause of cancer metastasis to the skeleton. However, when melanoma does metastasize, one of the most common sites is the skeleton. In the literature, there are very few reports of bone metastasis and bone fracture from malignant melanoma, but they do clearly occur

Malignant Melanoma. Metastatic melanoma, otherwise known as malignant melanoma, is a chronic form of skin cancer. The melanoma cancer occurs in cells called melanocytes, which produce melanin.

The stage of a melanoma tells you how deeply it has grown into the skin, and how far it has spread. Doctors use different systems to stage melanoma. These include the TNM system or number staging system. Or they might use the Clark or Breslow scale to describe how deeply the melanoma has grown into your skin

Choroidal melanoma presentation peaks at the age of 60 years with a higher incidence in Caucasians

Malignant Melanoma is a common skin cancer that arises from the melanin cells within the upper layer of the skin (epidermis) or from similar cells that may be found in moles (nevi). This type of skin cancer may send down roots into deeper layers of the skin. Some of these microscopic roots may spread (metastasize) causing new tumor growths in. Oral malignant melanoma is largely a disease of those older than 40 years, and it is rare in patients younger than 20 years. The average patient age at diagnosis is 56 years.

This study was conducted to investigate the metastatic behavior, timing, patterns, survival, and influencing factors in MM. 214 patients with MM were evaluated retrospectively. Distant metastases (82%) were the most frequent for patients initially metastatic While a good fur coat generally protects our pets from sun-induced malignant melanoma, a melanoma diagnosis is still just as serious and potentially deadly in our pets as it is for people Nodular melanoma occurs in at least 10%-15% of cases.

At first, the expression level of NLE1 in malignant melanoma and adjacent normal tissues was detected by immunohistochemistry (IHC), indicating that the expression of NLE1 in melanoma tissues is highly expressed (p<0.001, Table 1).A more intuitive result can be represented by the image shown in Fig. 1A. Moreover, the results of relationship between NLE1 and tumor characteristics in patients. Malignant melanoma is a highly aggressive cancer that tends to spread to other parts of the body.
