Ultrastructural and molecular confirmation of the trichodysplasia spinulosa‐associated polyomavirus in biopsies of patients with trichodysplasia spinulosa

Journal of Cutaneous Pathology, 2012
Trichodysplasia spinulosa (TS) is a rare and only recently characterized cutaneous disease occurring in immunocompromised patients. The disease is characterized by spiny follicular papules on clinical examination and by the presence of viral inclusions at ultrastructural examination.

Trichodysplasia Spinulosa: Rare Presentation of Polyomavirus Infection in Immunocompromised Patients

Journal of Cutaneous Medicine and Surgery, 2014
Background: Trichodysplasia spinulosa (TS) is a rare, striking, folliculocentric papular eruption seen exclusively in immunosuppressed patients. The eruption can be disfiguring, associated with leonine faces and alopecia. TS is caused by a polyomavirus, identified as trichodysplasia spinulosa polyomavirus (TSPyV)

Viremia and viruria of trichodysplasia spinulosa-associated polyomavirus before the development of clinical disease in a kidney transplant recipient

Transplant Infectious Disease, 2019
AbstractTrichodysplasia spinulosa (TS) is a rare disease associated with immunosuppression and induced by a polyomavirus denominated Tricodisplasia Polyomavirus (TSPyV). We report a case of TS 6 months after kidney transplantation in a 65 years‐old woman under immunosuppression therapy with prednisone, mycophenolate and tacrolimus.

Detection of Beta–Human Papillomavirus in a Child With Polyomavirus-Associated Trichodysplasia Spinulosa

The American Journal of Dermatopathology, 2017
Abstract: Viral associated trichodysplasia spinulosa (VATS) is a rare cutaneous eruption characterized by folliculocentric papules, keratin spicules, and alopecia associated with trichodysplasia spinulosa–associated polyomavirus (TSPyV) infection.

Production and characterization of monoclonal antibodies specific for major capsid VP1 protein of trichodysplasia spinulosa-associated polyomavirus

Microbiology and Immunology, 2018
ABSTRACTTrichodysplasia spinulosa‐associated polyomavirus (TSPyV), a newly identified polyomavirus, has been implicated as a causative agent of trychodysplasia spinulosa (TS), a rare proliferative skin disease in severely immunocompromised hosts. Diagnosis using mAbs is a promising tool with high specificity towards the specific antigen.

Emerging differential roles of the pRb tumor suppressor in trichodysplasia spinulosa-associated polyomavirus and Merkel cell polyomavirus pathogeneses

Journal of Clinical Virology, 2016
Merkel cell carcinoma (MCC) and trichodysplasia spinulosa (TS) are two proliferative cutaneous diseases caused by the Merkel cell polyomavirus (MCPyV) and trichodysplasia spinulosa-associated polyomavirus (TSPyV) respectively. Recently, studies have elucidated a key role of the small tumor (sT) antigen in the proliferative pathogenic mechanisms of ...

Trichodysplasia spinulosa : une infection à polyomavirus chez un patient immunodéprimé

Revue Francophone des Laboratoires, 2014
Introduction La trichodysplasia spinulosa (TS) est une maladie cutanee rare survenant chez les patients immunodeprimes, due a une infection par un virus de la famille des polymomavirus, le TSPyV. Nous rapportons un cas pediatrique qui illustre les difficultes therapeutiques et, pour la premiere fois, suggere, une cible cellulaire specifique, le ...

Trichodysplasia spinulosa : une primo-infection à polyomavirus chez un patient transplanté rénal

Annales de Dermatologie et de Vénéréologie, 2019
Introduction Les polyomavirus humains (PyVH), comme le virus JC ou BK, sont ubiquitaires et deviennent pathogenes en se reactivant d’un etat de latence, particulierement chez les sujets immunodeprimes (ID). En 2010, un nouveau polyomavirus (TSPyV) a ete associe a la trichodysplasia spinulosa (TS), une maladie cutanee rare observee chez les patients ...
