Abstract

Atypical Spitz tumors can hardly be differentiated from spitzoid melanoma. CGH might help in the differential diagnosis. An 8 year old child with an atypical Spitz tumor (with a CGH pattern compatible with melanoma) of 8.0 mm Breslow thickness and micrometastases in two lymph node regions was seen at our department. The management and prognosis of atypical Spitz tumors is controversial, and aggressive procedural steps similar to melanoma are usually not recommended. Even performing sentinel lymph node biopsy has been questioned. After extensive interdisciplinary consultations, we did not recommend resection of both lymph node regions and chose instead to follow-up with regular whole-body MRI and adjuvant treatment with pegylated interferon. Treatment decisions for atypical Spitz tumors are a major medical and ethical challenge due to the limited available data.
