Spitz nevus
My personal experience shows that spitz nevus is not as rare as it is published in medical literature. In many cases dermatoscopic features are typical, which allows presumptive diagnosis. Adults should be referred to a biopsy to avoid diagnostic errors.
The risk of developing melanoma in children with a typical appearance of spitz nevus is very low, but surgical treatment may be considered depending on clinical factors such as age, medical history, and growth pattern of the nevus.
