ABSTRACT
ABSTRACT We present the case of a prepubescent man of African descent who developed a spitzoid melanocytic proliferation showing evidence of a novel promoter hijacking ALK-C2orf42 rearrangement, with atypical histology, clinically apparent metastatic disease, and abnormal cytogenetic findings, representing a rare genuine case of "Spitz melanoma of childhood." As our understanding of the distinct molecular biology of different tumors traditionally grouped as spitzoid melanocytic lesions evolves, it is becoming increasingly apparent that this group encompasses morphologically and genetically distinct entities. Accurate classification with detailed molecular analysis and prolonged clinical follow-up is essential to allow meaningful conclusions regarding prognostication and prediction of response to therapy.
