A case of pediatric thyroid carcinoma

We reported a case of pediatric thyroid carcinoma. A 10-year-old girl seen for dyspnea on exertion due to bilateral laryngeal paralysis. This was found to have a thyroid tumor in preoperative computed tomography (CT) examination of bilateral laryngeal paralysis. It was diagnosed with papillary carcinoma in fine needle aspiration cytology. We undertook left thyroid lobectomy with isthmus and left side neck dissection. Tracheostomy and glottic dilation was performed to improved dyspnea after thyroid lobectomy. The tumor was diagnosed as poorly differentiated carcinoma with invasion beyond the thyroid capsule, and multiple cervical lymph node metastases were diagnosed histopathologically. Dyspnea was improved by glottic dilation and the tracheosoma could be closed postoperatively. The girl remains alive without recurrence in the 2 years and 6 months since surgery.
