Cutaneous Malignancy in Children

Lauren Mutterly presented on cutaneous malignancy in children, focusing on pediatric melanoma, atypical Spitz tumors, and other skin-related issues. Pediatric melanoma, though rare, constitutes 1-4% of all melanomas, mainly occurring in adolescents, particularly Caucasians. Notably, 5-7% of pediatric melanoma cases have a family history. The clinical presentation can differ significantly from adults, leading to potential diagnostic delays; many pediatric patients have atypical features that diverge from the conventional ABCDE criteria. A new proposed criteria considers factors like color uniformity and the nature of the lesion's development. The histopathological landscape in children often includes spitzoid tumors, complicating differentiation between benign and malignant forms. Regarding non-invasive testing for lesions, current methods lack validation in pediatric patients and are not recommended. Furthermore, pediatric melanoma has a better prognosis than in adults, with high survival rates across early stages. Transitioning to melanonychia, subungual melanoma is extremely rare in children, and benign conditions may mimic worrisome characteristics that usually pertain to adult subungual melanoma. For other malignancies, the identification of soft tissue tumors is crucial, as they represent significant pediatric cancers. Recommendations for evaluation include thorough medical histories and imaging to differentiate benign from malignant tumors. The presentation covered various malignancies like neuroblastoma, leukemia cutis, rhabdomyosarcoma, and infantile fibrosarcoma, emphasizing the need for careful assessment and potentially urgent referral for pediatric patients.
