Neurocan expression associates with better survival and viral positivity in Merkel cell carcinoma.

open access: yesPLoS ONE, 2023
Merkel cell carcinoma (MCC) is a rare cutaneous neuroendocrine carcinoma that is frequently divided into Merkel cell polyomavirus negative and positive tumors due their distinct genomic and transcriptomic profiles, and disease outcomes.

Merkel cell carcinoma: epidemiology, clinical features, diagnosis and treatment of a rare disease

open access: yesAnais Brasileiros de Dermatologia, 2023
Merkel cell carcinoma is a rare skin cancer with neuroendocrine differentiation. The risk factors include sun exposure, advanced age, immunosuppression (such as transplant recipients, patients with lymphoproliferative neoplasms, or patients with HIV ...

Taking the Scenic Route: Polyomaviruses Utilize Multiple Pathways to Reach the Same Destination

open access: yesViruses, 2020
Members of the Polyomaviridae family differ in their host range, pathogenesis, and disease severity. To date, some of the most studied polyomaviruses include human JC, BK, and Merkel cell polyomavirus and non-human subspecies murine and simian virus 40 ...

Inflammatory Monocytes Are a Reservoir for Merkel Cell Polyomavirus [PDF]

open access: yesJournal of Investigative Dermatology, 2010
Merkel cell polyomavirus (MCPyV) is a recently discovered virus that is implicated in the oncogenesis of Merkel cell carcinoma (MCC). The route of dissemination and the reservoir(s) of MCPyV within the human body have not yet been identified. In this study we describe two patients with multiple MCPyV-positive inflammatory and neoplastic skin lesions at

Diagnostic Methods for and Clinical Pictures of Polyomavirus Primary Infections in Children, Finland

open access: yesEmerging Infectious Diseases, 2014
We used comprehensive serodiagnostic methods (IgM, IgG, and IgG avidity) and PCR to study Merkel cell polyomavirus and trichodysplasia spinulosa-associated polyomavirus infections in children observed from infancy to adolescence. Comparing seroconversion

Merkel cell carcinoma: an updated guide for pathologists

open access: yesHistopathology, EarlyView.
Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma for which the differential diagnosis can include other small cell malignancies (especially metastatic small cell carcinoma) or cutaneous carcinoma. Morphologic and immunophenotypic aberrancies in MCC can increase diagnostic challenge.

Burden and Correlates of Multiple Chronic Infections and Their Associations With Cancer Incidence in Chinese Adults: A Large Case‐Cohort Study

open access: yesInternational Journal of Cancer, Volume 159, Issue 5, Page 1282-1295, 1 September 2026.
While several oncogenic pathogens cause site‐specific cancers, uncertainties remain about many other chronic infections and combined pathogen effects, especially in non‐Western populations. Using a large case–cohort study nested within the China Kadoorie Biobank, the authors found that co‐infection was common, with a mean of 10 pathogens per individual.

A Snapshot of the UK Blood Donor Plasma Virome: A Retrospective Cross‐Sectional Cohort Study

open access: yesJournal of Medical Virology, Volume 98, Issue 8, August 2026.
ABSTRACT Estimates of population prevalence and genetic diversity of bloodborne viruses in healthy humans are essential to support population‐scale monitoring for transfusion transmission risk. In the UK and globally, blood donations are routinely screened for a limited number of high‐consequence pathogens, but the full composition of the plasma virome

Prevention of Oncogenic Gammaherpesvirinae (EBV and HHV8) Associated Disease in Solid Organ Transplant Recipients

open access: yesTransplant International, 2023
Long-term risk for malignancy is higher among solid organ transplant (SOT) recipients compared to the general population. Four non-hepatitis viruses have been recognized as oncogenic in SOT recipients—EBV, cause of EBV-associated lymphoproliferative ...

Merkel Cell Carcinoma and Immunosuppression, UV Radiation, and Merkel Cell Polyomavirus.

open access: yesJAMA Dermatol
ImportanceMerkel cell carcinoma (MCC) is a rare but aggressive skin cancer. Quantifying the contribution of major potentially modifiable risk factors to the burden of MCC may inform prevention efforts.ObjectiveTo estimate the population attributable fraction of MCC cases in the US that were attributable to major immunosuppressing conditions (eg, HIV ...
