Confetti-like depigmentation: A potential sign of rapidly progressing vitiligo.

BACKGROUND: Confetti-like depigmentation was noted in patients reporting recent worsening of vitiligo. OBJECTIVE: We sought to determine if confetti-like depigmentation is a marker of rapidly progressing vitiligo. METHODS: Review of patient records and images of patients from a vitiligo registry resulted in 7 patients with 12 images that fit inclusion criteria and were evaluated for percent depigmentation by 3 independent reviewers. The Vitiligo Disease Activity Score and the Koebner Phenomenon in Vitiligo Score in an additional cohort of patients with confetti-like lesions were compared with patients who had vitiligo without confetti-like lesions. RESULTS: The mean percentage of depigmentation at baseline was 19.2%, which increased to 43.9% in images obtained at a mean of 16 weeks of follow-up. Vitiligo Disease Activity Score and Koebner Phenomenon in Vitiligo Score were significantly higher in the patients with confetti-like lesions compared with those without confetti-like lesions. A skin biopsy specimen of a confetti-like lesion in 1 patient revealed an inflammatory infiltrate in the papillary dermis with CD8(+) T cells localized to the dermoepidermal junction. LIMITATIONS: Small, single-center retrospective review and lack of full-body photographs are limitations. CONCLUSIONS: A confetti-like pattern of depigmentation may be a negative prognostic indicator for patients with rapidly progressing vitiligo. Further, prospective studies to evaluate this physical finding should be performed.

Primary cutaneous zygomycosis secondary to minor trauma in an immunocompromised pediatric patient: a case report.

Zygomycosis is an opportunistic infection generally found in immunocompromised individuals. Herein we present a pediatric patient with primary cutaneous mucormycosis that developed at a site of trauma. Diagnosis and treatment are discussed.
