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. We report a case of a 6-year-old male child who presented with a generalized papular eruption during chemotherapy for acute lymphoblastic leukemia. The papules were tested for human papillomavirus (HPV) DNA by nested polymerase chain reaction (PCR) and TSPyV using PCR and gene sequencing studies. The lesions were positive for TSPyV by PCR combined with sequencing and showed high copy number with real-time PCR, and beta-papillomavirus was identified by PCR and sequencing. Immunohistochemistry revealed inner root sheath keratinocytes expressing nuclear HPV L1 capsid antigen. To our knowledge, this is the first case of concomitant productive HPV and TSPyV infection in a VATS-affected patient. The presence of HPV may be coincidental, however, further studies are needed to establish whether specific HPV genotypes influence the development of abnormal inner root sheath trichohyalin granules found in VATS.

D027383 Papillomaviridae A family of small, non-enveloped DNA viruses infecting birds and most mammals, especially humans. They are grouped into multiple genera, but the viruses are highly host-species specific and tissue-restricted. They are commonly divided into hundreds of papillomavirus "types", each with specific gene function and gene control regions, despite sequence homology. Human papillomaviruses are found in the genera ALPHAPAPILLOMAVIRUS; BETAPAPILLOMAVIRUS; GAMMAPAPILLOMAVIRUS; and MUPAPILLOMAVIRUS.
D027601 Polyomavirus Infections Infections with POLYOMAVIRUS, which are often cultured from the urine of kidney transplant patients. Excretion of BK VIRUS is associated with ureteral strictures and CYSTITIS, and that of JC VIRUS with progressive multifocal leukoencephalopathy (LEUKOENCEPHALOPATHY, PROGRESSIVE MULTIFOCAL). Polyomavirus Infection
D030361 Papillomavirus Infections Neoplasms of the skin and mucous membranes caused by papillomaviruses. They are usually benign but some have a high risk for malignant progression.
