Spitzoid melanocytic lesions describe a spectrum of pediatric melanocytic proliferations ranging from benign Spitz nevi to malignant spitzoid melanomas typically arising within the first two decades of life. Atypical spitzoid neoplasm (ASN) is a poorly defined category within this spectrum that poses a unique diagnostic challenge due to histologic findings with insufficient atypical characteristics to make the diagnosis of melanoma. This report presents an exceptionally rare case of an ulcerative atypical spitzoid neoplasm mimicking an infantile hemangioma in a two-month-old girl treated with pulse dyed laser (PDL) and surgical excision. Our patient ultimately underwent five excisions over a 2-year period, with successful maintenance of function and dexterity of the affected fingers.
