Surgery for benign and malignant diseases of the thyroid gland in childhood.

From 1970 to 1986, 51 children and adolescents aged 5-18 years were operated on for diseases of the thyroid gland, among them 42 with benign diseases (juvenile goiter 21, adenoma 17, Graves' disease 3, Hashimoto's thyroiditis 1) and nine with malignancies (papillary carcinoma 4, follicular carcinoma 3, medullary carcinoma 1, anaplastic carcinoma 1). In benign entities, females were three times as often affected as males, whereas both sexes were equally affected in malignancies. Positive family histories were found in 23.3% of the children with adenomas in 71.4% of the children with juvenile goiters. Subtotal strumectomy was carried out in 30 instances and enucleation in 12. Iodized salt and L-thyroxine were given postoperatively as recurrence prophylaxis. Recurrence was seen in two children (4.8%) who had no recurrence prophylaxis. Symptoms in children with malignancies were palpable cervical lymph nodes and solitary nodes in the thyroid gland. Total thyroidectomy was done in all instances, followed by radio-iodine treatment in eight cases and cobalt 60 irradiation in one case. Two children died, of diffuse metastases and irradiation fibrosis of the lung respectively. The peculiarities of diseases of the thyroid gland in childhood that require surgery are discussed.
