Background Data regarding the course and treatment of pigmented purpuric dermatoses (PPD) in the paediatric population are limited. Although treatments for pigmented purpura are not well established, vitamin C and rutoside have been reported to be an effective treatment option and are widely utilized. Objective To assess the clinical course and utility of vitamin C and rutoside in paediatric patients with PPD treated at Ann & Robert H. Lurie Children’s Hospital of Chicago between 2008 and 2018. Methods A retrospective review of all children with PPD managed at our hospital between 2008 and 2018 was performed. Additional follow‐up was obtained via telephone interviews. Results A total of 101 patients met inclusion criteria. The female: male ratio was 1.3 : 1, and the median age at diagnosis was 8.8 years (IQR, 5.7–12.9). Median follow‐up was 7.13 months (IQR, 3–17.4). The most common PPD subtypes were lichen aureus (43%) and Schamberg (34%). Fifty‐three (52%) patients had evaluable follow‐up documentation via their medical record or phone questionnaire. Twenty‐eight patients were treated with vitamin C or rutoside or combination therapy. Twenty‐five patients received no treatment. Clearance of the rash was noted in 24 (45.3%) patients overall, including 10 (42%) patients in the treated group and 14 (58%) patients in the untreated group. Recurrence was noted in seven (13.2%) patients. Treatment with vitamin C and/or rutoside was well tolerated without side effects. None of the patients were subsequently diagnosed with vasculitis, coagulopathy or cutaneous T‐cell lymphoma. Conclusion Pigmented purpuric dermatosis in children is a benign disorder with high rates of complete resolution. Treatment with vitamin C and rutoside is well tolerated, but in this cohort, there did not appear to be an advantage over watchful waiting without therapy.
