Trichodysplasia spinulosa polyomavirus (also known as Trichodysplasia spinulosa-associated polyomavirus, abbreviated TSPyV or TSV) is a member virus of Human polyomavirus 8 [1] that infects human hosts. First discovered in 2010, TSPyV is associated with Trichodysplasia spinulosa, a rare skin disease only seen in immunocompromised patients. [2]
Trichodysplasia spinulosa (also known by many other names, including viral-associated trichodysplasia spinulosa, viral-associated trichodysplasia, pilomatrix dysplasia and ciclosporin-induced folliculodystrophy, although the last is a misnomer) is a rare cutaneous condition that has been described almost exclusively in immunocompromised patients, usually organ transplant recipients, on ...
MCV is highly divergent from the other human polyomaviruses and is most closely related to murine polyomavirus. Trichodysplasia spinulosa-associated polyomavirus (TSV) is distantly related to MCV. Two viruses—HPyV6 and HPyV7—are most closely related to KI and WU viruses, while HPyV9 is most closely related to the African green monkey ...
All known human polyomaviruses are fairly common in healthy adult populations and are usually asymptomatic. In studies that profile polyomavirus seroprevalence, or prevalence of detectable antibodies against viral proteins indicating either past or present exposure in immunocompetent adults, HPyV9 tends to have a relatively lower prevalence compared to other human polyomaviruses.

However, evidence of MTag encoding and expression has also recently been reported in at least one virus of unrelated lineage, the trichodysplasia spinulosa polyomavirus, which is a normally asymptomatic infection in humans that sometimes causes the rare disease trichodysplasia spinulosa in immunocompromised individuals. [7]
All known human polyomaviruses are fairly common in healthy adult populations and are usually asymptomatic. In studies that profile polyomavirus seroprevalence, or prevalence of detectable antibodies against viral proteins indicating either past or present exposure in immunocompetent adults, estimates of HPyV6 prevalence have ranged from approximately 60–85%, with evidence of low prevalence ...
Human polyomavirus 7 (HPyV7) is a virus of the polyomavirus family that infects human hosts. It was discovered in 2010 and is a common component of the skin flora in healthy adults. [ 1 ] There is limited evidence from case reports linking the virus to a skin rash occurring in immunocompromised organ transplant recipients.
