Trichodysplasia Spinulosa in a 7-Year-Old Boy Managed Using Physical Extraction of Keratin Spicules.

Abstract

Trichodysplasia spinulosa (TS) is an uncommon skin disease characterized by a folliculocentric papular eruption and keratin spine formation, classically appearing on the central face and ears. It occurs in immunosuppressed patients and is linked to a viral etiology. Diagnostic tests including polymerase chain reaction (PCR) are available for detection of the TS-associated polyomavirus. Effective treatment options include topical cidofovir and oral valganciclovir. We present a case diagnosed using PCR with skin scrapings and treated using physical extraction of the keratin spicules. Significant improvement was noted, suggesting a safe, cost-effective treatment alternative.
