Mixed Papillary and Follicular Carcinoma ina Farty-one-Year-Old Exposed Woman( less retarded than these patients) have levels of protein-bound iodine that have remained normal. However, it is significant that recent TSH deter- ‘ minations showed slightly élevated levels in 2 of the less retarded children. Two of the bovs ( and .) with thyroid nodules were in the group Leasesoap pts ae! with retardation of vrowth and development. It is interesting in these latter cases that, though the levels of protein-bound iodine were normal, 1 had a eee ), Showing a Malignant Nodule in Part of the Excised Gland (A), an Area of Follicular Cancer (B), Metastatic Invasion (C) of a Blood Vesset (Elastic Stain) and Invasion ofa Lymph Node (D). I0129b0 slightly elevated TSH level (9.6 millimicrogm. per milliliter), and both showed almost no response to TSH stimulation. The possible correlation of growth retardation with thyroid irradiation will be discussed later. After extensive discussion, it was decided to institute treatment with levothyroxine in the more heavily exposed group, which was done in September, 1965. PRIVACY ACT MATERIAL REMOVED
