Merkel Cell Polyomavirus in Cutaneous Swabs
To assess the usefulness of using cutaneous swabs to detect Merkel cell polyomavirus (MCPyV) DNA, we analyzed swabs from persons with Merkel cell carcinoma (MCC), others with skin diseases, and healthy volunteers. MCPyV was detected in at least 1 sample from virtually all participants. Viral loads were higher in samples from patients with MCC.
متن کاملMerkel cell polyomavirus and cutaneous Merkel cell carcinoma
Merkel cell carcinoma (MCC) is a rare aggressive neuroendocrine skin cancer of elderly patients. Generally, it originates from Merkel cells of the basal layer of the epidermis characterized by typical neuroendocrine granules (neuron-specific enolase; NSE+) and keratin filament (cytokeratin-20; CK20). Its incidence has been increasing in the last two decades, likely because of improved ability t...
متن کاملMerkel Cell Polyomavirus Strains in Patients with Merkel Cell Carcinoma
We investigated whether Merkel cell carcinoma (MCC) patients in France carry Merkel cell polyomavirus (MCPyV) and then identified strain variations. All frozen MCC specimens and 45% of formalin-fixed and paraffin-embedded specimens, but none of the non-MCC neuroendocrine carcinomas specimens, had MCPyV. Strains from France and the United States were similar.
متن کاملMerkel Cell Polyomavirus DNA in Persons without Merkel Cell Carcinoma
Merkel cell polyomavirus (MCPyV) DNA was detected in 88% of Merkel cell carcinomas in contrast to 16% of other skin tumors. MCPyV was also found in anogenital and oral samples (31%) and eyebrow hairs (50%) of HIV-positive men and in forehead swabs (62%) of healthy controls. MCPyV thus appears to be widespread.
متن کاملMerkel Cell Polyomavirus: A Causal Factor in Merkel Cell Carcinoma
The RNA viruses hepatitis C virus and human T-cell lymphotropic virus type I (or human T-cell leukaemia virus type 1), and the DNA viruses hepatitis B virus, high-risk human papillomaviruses, human herpes virus-8 (Kaposi’s sarcoma-associated herpes virus) and Epstein Barr virus are acknowledged as carcinogenic to humans. Human polyomaviruses have oncogenic potentials in cell cultures and animal...
