Question 16

Answer 16

Trichodysplasia spinulosa presents with numerous erythematous to skin-colored papules with a central spiny projection on the face (especially the mid portion), ears, and less often extremities and trunk.

Associated alopecia of the eyebrows and eyelashes,
or less often other facial and body hair, as well as thickening of the skin resulting in a leonine appearance may develop. Histologic evaluation is characterized by dilated anagen follicles with abnormal maturation and eosinophilic keratinocytes containing large trichohyaline granules. Large eosinophilic inclusions within affected keratinocytes show positive immunohistochemical staining for the
polyomavirus middle T antigen, and electron microscopy demonstrates intranuclear icosahedral viral particles. The diagnosis can be confirmed by PCR-based viral detection in skin scrapings or a biopsy specimen.

Trichodysplasia spinulosa may improve following reduction
or discontinuation of immunosuppressive medications, and successful treatment with topical cidofovir, oral valganciclovir, and leflunomide has been described. Trichodysplasia spinulosa-like hyperkeratosis has also been described in a patient with basal cell nevus syndrome treated with vismodegib
