Trichodysplasia spinulosa is a rare cutaneous disease caused by the trichodysplasia spinulosa-associated polyomavirus. It occurs more frequently in immunocompromised patients, particularly in solid organ transplants. A few successful treatments have been described in the literature. In our report, we present a biopsy-proven trichodysplasia spinulosa case in a kidney transplant recipient who rapidly responded to a reduction of his immunosuppressive therapy.
