[Differentiated thyroid carcinoma in childhood].
We report the cases of 6 patients, all younger than 14 years of age, with differentiated thyroid carcinoma. None of the patients had a previous history of radiation exposure. All patients presented with an enlarged thyroid gland as a solitary nodule, with or without cervical nodes. The fine-needle aspiration cytological examination was found to be the most sensitive and specific, evidencing 5 pure papillary adenocarcinoma and 1 follicular. Our standard preoperative evaluation included thyroid scintiscan and ultrasound examination, laboratory studies of thyroid function and serum calcitonin, chest x-ray, fine needle aspiration and vocal cord examination. The treatment was total thyroidectomy and bilateral modified neck dissection. A whole body scan (WBS) with 131I was performed 6 weeks after surgery, followed by radioiodine therapy for ablation of thyroid remnants and treatment of metastases when present. Patients then began thyroid replacement treatment. The follow-up of the patients consisted of thyroglobulin and WBS. The microscopic carcinoma was found in the contralateral lobe in 100%. Lung metastases were detected in 2 patients. All of the patients have survived during a follow-up period ranging from 6 to 108 months.
