Abstract
Familial occurrence of thyroid carcinoma, one of the patients was in childhood, has not been reported in Japan. We have experienced the carcinoma occurring in a mother and her son. Case 1: A 14-year-old boy with bilateral cervical tumors was admitted to our hospital and total thyroidectomy was performed. Histological diagnosis was papillary carcinoma of the thyroid. Case 2: (mother of Case 1) A 37-year-old female with right cervical tumor underwent right hemithyroidectomy. Histological diagnosis was follicular carcinoma of the thyroid. She has been completery free from any recurrence or metastsis for the following eight years. Eighty-two cases of thyroid carcinoma in childhood, including our cases, were collected from Japanese literatures arid reviewed. We were able to collect a total of thirty-five cases of familial occurrence of thyroid carcinoma from European and American literatures.
