Malignant skin tumors: Kids are not just little people

Skin tumors are a clinically heterogeneous group of dermatologic conditions that affect both children and adults. Although similar types of skin tumors can affect both children and adults, the epidemiology, pathogenesis, and treatment of these skin neoplasms can vary drastically in children compared with adults. Despite the clear need for literature elucidating the differences of skin tumors in children compared with adults, there is a serious dearth of scientific contributions addressing this area. This contribution highlights the types of differences that can occur between adults and children with skin neoplasms, as well as the special considerations that need to be recognized when managing skin tumors in children by providing a comparative analysis of basal cell carcinoma, squamous cell carcinoma, and Kaposi sarcoma occurring in adults with these same tumors occurring in children. Specifically, we examine the aforementioned tumors with a focus on (1) epidemiology, (2) etiology, (3) clinical presentation, (4) workup, and (5) treatment.
