Abstract:
We describe a 10-year-old girl with paraspinal alveolar rhabdomyosarcoma (RMS) who presented with an asymptomatic soft tissue mass on the left aspect of the parietal scalp of 2 weeks' duration. Biopsy demonstrated metastasis of her RMS. A full-body positron emission tomography (PET) scan revealed multiple areas of increased uptake consistent with extensive metastases. We also discuss the literature on RMS classification and metastasis to the skin.
