Abstract
Objectives To describe the morphologic characteristics of skin lesions, extent of extracutaneous disease, and outcomes in patients with neonatal presentation of Langerhans cell histiocytosis (LCH), and to examine clinical predictors of disease prognosis. Design Retrospective validation cohort study. Maximum duration of follow-up was 10 years. Setting A tertiary care children's hospital in Chicago, Ill. Patients Nineteen children with cutaneous findings in the first 4 weeks of life and subsequently diagnosed with LCH based on compatible tissue histologic analysis, confirmed by electron microscopy and/or immunohistochemical analysis. Main Outcome Measure Cutaneous lesion morphologic characteristics, extracutaneous manifestations, treatments, and outcomes were tabulated and compared. Results The most common initial skin lesion was erythematous, often crusted, vesiculopustules. Skin lesion morphologic traits did not correlate with extent of extracutaneous disease. One third of patients had disease limited to the skin and/or mucous membranes. All of these patients are alive and well, and 1 has developed diabetes insipidus. Twelve of the 19 patients had multisystem disease, and 2 died of disease. The results of a multiorgan workup performed at the time of diagnosis were predictive of which patients in this cohort manifested multisystem disease. The overall incidence of diabetes insipidus was 21%. Conclusions Vesiculopustular lesions are common in congenital/neonatal LCH, but the morphologic characteristics of lesions are not helpful in predicting the extent of disease. A multiorgan evaluation at the time of diagnosis may be predictive of the probability of multisystem involvement with LCH.Keywords
