Differential DiagnosisHistory:
I think this little girl had the inflammatory variant of Pityriasis lichenoides (PLEVA).The necrotic papules were suggestive.She was not ill.Chickenpox and an inflammatory reaction to molluscum contagiosum were also considered in the differential diagnosis.Lymphomatoid papulosis would not be so extensive.Her bloods were all normal.She responded to erythromycin after about a week's therapy.A viral exanthem would also be in the differential.
