title: The thyroid: an extremely rare primary site of neuroblastoma.
abstract: Neuroblastoma (NB) is uncommon in the adolescent age group. It is located at any site containing sympathetic neural tissue, with retroperitoneal and adrenal lesions being the most common. Cutaneous and subcutaneous metastases of NB in children are infrequent. Primary thyroid NB with regional lymph node and distant multiple subcutaneous metastases was diagnosed in an 11-year-old boy. The differential diagnosis was primitive neuroectodermal tumor. Our case demonstrates the unique presentation of NB in an adolescent.
