ABSTRACT
Two adolescent females presented to outpatient clinic with isolated, non-scaly, asymptomatic hypopigmented macules and patches on the arm(s). Both cases had Wood's lamp exams notable for extralesional punctiform coral-red perifollicular fluorescence on the back and faint intralesional enhancement. In one case, biopsy was performed and deemed consistent with progressive macular hypomelanosis. The patient had complete response to antimicrobial therapy and sun exposure.

PURPOSE OF REVIEW: Children with systemic malignancies can present with concomitant dermatological manifestations. Cutaneous findings can occur before, during or after diagnosis. Recognizing these features can aid in diagnosis, inform prognosis, and help determine appropriate treatment. Following a review of the literature published over the past two years, we provide an update on cutaneous signs of pediatric systemic malignancies, concentrating on; leukemia cutis, lymphoma cutis, neuroblastoma, sarcomas, Langerhans cell histiocytosis and paraneoplastic syndromes. RECENT FINDINGS: Authors highlight the persistently heterogeneous features of cutaneous manifestations of systemic malignancy. Findings are often nonspecific, and a definitive diagnosis requires skin biopsy with immunophenotyping. Several studies describe dermoscopy features, demonstrating this as a useful tool in clinical evaluation. Genetic mutations underlying the pathogenesis of disease continue to be elucidated. Further, advances in medical treatment led to improved prognosis in many systemic malignancies, with early and aggressive treatment heralding better outcomes. SUMMARY: Comprehensive cutaneous evaluation alongside thorough clinical history and review of systems remains of paramount importance as dermatological manifestations of systemic malignancy are notoriously variable with a shared feature of often appearing benign but persisting despite usual treatment. Urgent referral to dermatology is recommended when suspicion for any cutaneous presentation of malignancy arises.
