“…Factors recognized as associated with poor prognosis are size of the tumor and presence of metastases according to the AJCC staging (4,47,55,(64)(65)(66)(67)(68), and immunosuppression (65,69,70). Recently, histological and immunochemistry markers have been described as potentially associated with poor outcome like low tumor infiltrating CD8 + T cells (101) and P53 and P63 expression and gen mutations (54, 68, 74) ( Table 2).…”

The Merkel cell polyomavirus (MCPyV), identified in humans in 2008, is associated with a relatively rare but aggressive neuroendocrine skin cancer, the Merkel cell carcinoma (MCC). MCC incidence is increasing due to the advancing age of the population, the increase in damaging sun exposure and in the number of immunocompromised individuals. MCPyV must be considered as the etiological agent of MCC and thus is the first example of a human oncogenic polyomavirus. MCPyV infection is common, and seroprevalence studies indicate that widespread exposure begins early in life. The majority of adults have anti-MCPyV antibodies and there is a growing body of evidence that healthy human skin harbors resident or transient MCPyV suggesting that MCPyV infection persists throughout life. However, the mode of transmission, the host cells, and the latency characteristics of this virus remain to be elucidated. In addition, it is still not clear whether MCPyV is associated with diseases or lesions other than Merkel cell carcinoma. The etiologic role of MCPyV in MCC opens up opportunities to improve the understanding of this cancer and to potentially improve its treatment.

Sentinel node mapping is an integral part of regional lymph node staging in many solid tumors and plays an important role in surgical oncology. This technique has been used with excellent results for non-melanoma skin cancers including Merkel Cell Carcinoma (MCC). In the current study, we reported our first MCC patient who underwent successful sentinel node mapping.We also reviewed the available literature regarding the prognostic significance of sentinel node mapping in cN0 MCC patients.

“…Primary tumor size was categorized as follows: less than 2 cm (T1), between 2 and 5 cm (T2), greater than 5 cm (T3), and tumor with deep invasion of extra dermal structures (T4), in accordance with the 2010 AJCC staging criteria for MCC (Table 1). 20 Primary tumor sites were evaluated in 4 categories: head and neck, trunk, upper extremity, and lower extremity. For this analysis, combined primary site-specific and disease process-specific causes of death were analyzed.…”

“…These data are comparable with previously cited literature by Tarantola et al 20 in their retrospective study and suggest possible future refinements to the current AJCC staging criteria for T stage, which currently only includes size (Table 1). 20 Treatment with WLE has been shown to improve disease-free survival, with margins of 1 to 3 cm recommended. [21][22][23] Nonpalpable microscopic nodal involvement occurs in about one third of clinically localized MCC.…”
