Trichodysplasia Spinulosa: A Polyomavirus Infection Specifically Targeting Follicular Keratinocytes in Immunocompromised Patients
Studysummary In this study, evidence that trichodysplasia spinulosa-associated polyomavirus targets follicular keratinocytes was observed in a pediatric case, suggesting these cells as the primary viral target.

Trichodysplasia spinulosa (TS) was identified as a rare skin disease affecting immunocompromised patients, caused by a specific polyomavirus. The study used polymerase chain reaction and skin biopsy immunostaining to demonstrate that follicular keratinocytes were the primary target of the trichodysplasia spinulosa-associated polyomavirus in a pediatric case. The pathophysiological mechanisms of TS remained not fully understood.
