Australas J Dermatol. 2014 May;55(2):e33-6. doi: 10.1111/ajd.12012. Epub 2013 Jan 18.

Abstract

Trichodysplasia spinulosa is a rare polyomavirus-associated cutaneous eruption occurring in the setting of immunosuppression. Clinically it is characterised by multiple centrofacial folliculocentric papules with spinous protuberances. The histopathology is distinct and treatment with antiviral agents appears to be the most effective.

Keywords: immunosuppression; polyomavirus; trichodysplasia spinulosa.
