A comparison of Merkel cell carcinoma and melanoma

Nonmelanoma skin cancer can refer to any cancer that forms in the basal, squamous or Merkel cells of the skin. Melanoma is a cancer that develops in the skin's melanocytes. Let's take a closer look at these skin cancers and how they differ from one another Only formally recognised in the early 1970s, Merkel cell carcinoma is a rare and deadly type of skin cancer. It's incidence is 30 times less common than melanoma. Without any particular features, it can be hard to diagnose Because Merkel cells are a type of neuroendocrine cell, Merkel cell carcinoma (MCC) is also sometimes called neuroendocrine carcinoma of the skin. Another name for MCC is trabecular carcinoma (or trabecular cancer). MCC is much less common than most other types of skin cancer (see below), but it's one of the most dangerous types

Merkel cell carcinoma (MCC) is a rare aggressive skin cancer with neuroendocrine differentiation. With immunohistochemistry, the tumor cells stain for both neuroendocrine (i.e., synaptophysin and chromogranin A) and epithelial markers. The epithelial marker cytokeratin 20 (CK20) stains positive with immunohistochemistry in a vast majority of MCCs He and his associates devised the acronym AEIOU to describe the clinical features of Merkel cell carcinoma based on an analysis of 195 patients given the diagnosis between 1980 and 2007 (J. Am. Acad. Dermatol. 2008; 58:375-81). The acronym stands for A symptomatic, E xpanding rapidly, I mmune compromised, O lder than 50, and U V-exposed, fair skin Skin cancer is the atypical growth of skin cells. The most common cause is prolonged exposure to the sun, but it can also develop in areas where no sunlight exposure has occurred. There are four types of skin cancer: basal cell carcinoma, squamous cell carcinoma, melanoma, and Merkel cell carcinoma Merkel cell carcinoma (MCC) is a rare skin cancer. It is also an aggressive skin cancer. MCC is considered aggressive because it can: Grow quickly and spread. Return after treatment. Because MCC is aggressive, doctors recommend prompt treatment.

Merkel cell carcinoma (MCC) is a rare but aggressive form of skin cancer, representing less than 1% of all non‐melanoma skin cancer. It typically presents as an erythematous nodule with relatively rapid growth. MCC lesions are most commonly found on sun‐exposed areas, particularly in older, fair‐skinned individuals Merkel cell carcinoma (MCC) is an aggressive neuroendocrine skin cancer with a case fatality rate that is three times that of malignant melanoma. MCC is an uncommon cancer with an estimated 2,500. Efficacy. There is little randomised evidence of the use of adjuvant therapy in the management of Merkel cell carcinoma. Historically, surgery has been the mainstay of treatment but this has been associated with high rates of locoregional failure if not followed by post-operative radiation therapy (RT) There are 2 main types of non-melanoma skin cancer - basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Basal cell carcinoma. BCC is the most common type of skin cancer. It makes up about 75%-80% of all skin cancers.

The term non-melanoma distinguishes these more common types of skin cancer from the less common skin cancer known as melanoma, which can be more serious. In the UK, around 147,000 new cases of non-melanoma skin cancer are diagnosed each year Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer [].Compared with other skin cancers, particularly melanoma, MCC is rarer and is associated with a worse prognosis; the 10-year overall survival rate for MCC is 18% vs. 61% for melanoma [].Risk factors for MCC include UV radiation exposure, advanced age, and a weakened immune system [] Squamous-cell skin cancer, also known as cutaneous squamous-cell carcinoma (cSCC), is one of the main types of skin cancer along with basal cell cancer, and melanoma. It usually presents as a hard lump with a scaly top but can also form an ulcer. Onset is often over months. Squamous-cell skin cancer is more likely to spread to distant areas than basal cell cancer There is limited randomised evidence to support the role of definitive radiation therapy in the treatment of patients with Merkel cell carcinoma (MCC). The Radiation Oncology reference committee (RC) supported the use of this protocol on the basis of the information summarised below
