Merkel cell (NE) carcinoma of the skin is an uncommon entity that was first described as trabecular carcinoma. 370 These tumors are uniformly positive for broad-spectrum cytokeratins and stain positively for CK20 in 97% of cases, with a dotlike pattern of reactivity (Fig. Merkel cells normally exist in the bottom (basal) layer of the epidermis, about 0.1 mm from skin's surface. 2020 Feb;128(2):104-120. doi: 10.1111/apm.13019. 2016 Mar 1;138(5):1153-62. doi: 10.1002/ijc.29862. The bump may be skin-colored or red-violet, and tends to grow rapidly over weeks to months. Normal Merkel cells in the skin: In this illustration of a cross-section of the skin, normal Merkel cells are shown in red and connect to nerves shown in yellow. Merkel cell carcinoma is a rare type of skin cancer that usually appears as a flesh-colored or bluish-red nodule, often on your face, head or neck. It is extremely rare in children and more common in whites and in men than in women. Merkel Cell Polyomavirus and Merkel Cell Carcinoma. Merkel cell carcinoma is an aggressive neuroendocrine cutaneous malignancy with a predilection for regional and distant metastasis. Transplant. It can be hard to treat if it spreads beyond the skin. It usually develops as a single, painless, bump on sun-exposed skin. Merkel cell carcinoma occurs when these cells grow out of control. HHS Dramatic Increase in the Incidence and Mortality from Merkel Cell Carcinoma in the United States. 2016 Jul;12(7):637-46. doi: 10.1200/JOP.2016.013367. Figure 1. Merkel Cell Carcinoma: Current United States Incidence and Projected Increases based on Changing Demographics. Mechanistically, artesunate predominantly induces ferroptosis in MCPyV-positive MCC cells since known ferroptosis-inhibitors like DFO, BAF-A1, Fer-1 and β-mercaptoethanol reduced artesunate-induced death. This site needs JavaScript to work properly. This malignancy presents most commonly on the head and neck of elderly Caucasian males, with a higher prevalence in the immunosuppressed. -, Fitzgerald T.L., Dennis S., Kachare S.D., Vohra N.A., Wong J.H., Zervos E.E. It is also known as neuroendocrine carcinoma of the skin, cutaneous APUDoma, and primary small cell carcinoma of the skin with endocrine differentiation. Since artesunate-a drug used to treat malaria-has been reported to possess additional anti-tumor as well as anti-viral activity, we sought to evaluate pre-clinically the effect of artesunate on MCC. Epub 2020 Jan 28. Merkel cell carcinoma (MCC) is a rare form of skin cancer. doi: 10.1016/S0041-1345(02)03065-8. Merkel cell carcinoma (MCC) is a rare and highly aggressive skin cancer with frequent viral etiology. Cross-section of skin, normal Merkel cells are shown in red and connect to nerves shown in yellow. This means that it rapidly grows and spreads to nearby tissues or distant parts of the body (metastasizes). Merkel cell carcinoma can be dangerous because it tends to grow quickly. Cancer Epidemiol. Merkel cell carcinoma is a disease of the elderly and usually affects individuals in their seventh and eighth decade of life with approximately 5% people aged <50 years being affected.  |  Oncol. Bone marrow involvement in MCC is rare and to our knowledge only nine cases reported in the English literature. Tetzlaff MT, Nagarajan P. Update on Merkel Cell Carcinoma. Merkel cell carcinoma usually appears as a single painless lump on sun-exposed skin. (, No signs of apoptotic cell death in most artesunate-treated MCC cells. Interestingly, in one MCC cell line (WaGa), T antigen knockdown rendered cells less sensitive to artesunate, while for two other MCC cell lines, we could not substantiate such a relation. It may spread quickly to surrounding tissues, nearby lymph nodes, or more distant parts of the body. Clinical trials are also an option.

Sun exposure and having a weak immune system can affect the risk of Merkel cell carcinoma. The cancer may derive from the microscopic Merkel cell nervous organ in the skin and viscera which is responsible for touch and pressure sensation. Arteries are depicted in red and veins are blue. The virus plays a causal role in Merkel cell carcinoma, a highly lethal form of skin cancer.

Merkel cell carcinoma (MCC) is an aggressive cutaneous malignancy with poor prognosis. The standard treatments for melanoma and Merkel cell skin cancer include surgery, targeted therapy, immunotherapy, and, less commonly, radiation therapy. NIH Limited data exists to guide treatment decisions. Major issues remain unanswered regarding its oncogenesis and optimal treatment. Identifying the mechanisms of oncogenesis allow experimentation of new therapeutic targets, which remain mandatory even at the era of immunotherapies. J.

Merkel cell carcinoma (MCC) is a rare but highly aggressive cutaneous tumour. Long-term sun exposure or a weak immune system may increase your risk of developing Merkel cell carcinoma.Merkel cell carcinoma tends to grow fast and to spread quickly to other parts of your body. 2, 3 The most frequent site of involvement is the head and neck region, followed by the extremities, the trunk, and the oral and genital mucosa. It is an aggressive type of cancer that can spread (metastasize) to other areas of the body. 3 It typically presents as an asymptomatic pink, red, or bluish firm dome-shaped nodule. Merkel cell carcinoma has a poor prognosis. MCC; Merkel cell carcinoma; artesunate; ferroptosis; polyomavirus.

Merkel cell carcinoma is also called neuroendocrine carcinoma of the skin.Merkel cell carcinoma most often develops in older people. Finally, application of artesunate in xenotransplanted mice demonstrated that growth of established MCC tumors can be significantly suppressed in vivo. He found these cells at high density in the paws of rats and surmised they may serve as “touch cells”. They were originally described in the late 1800s by Friedrich Merkel, a German anatomist.
