Mr. Edward J. Bauser 4, ~2- Development during the past year of nodules in the thyroid requiring definitive diagnosis and surgery. 3 (16%) Two young adults had the primary benign adenomatous goiter essentially identical with those in 1,3. above. They were treated by subtotal thyroidectomy and are recovering satisfactorily. The third Rongelapese, a girl now 21-22 years of age, was found to have a papillary adenoma with invasion by neoplastic cells of the lymph nodes of the left side of the neck, Since the frozen sections and invasiveness suggested a serious degree of malignancy, a radical dissection of the left side of the neck plus complete thyroidectomy were carried out. The patient is recovering with a minor degree of hypoparathyroidism. (None of six Ailinginae children exposed to an estimated external dose of 70 rads have shown <hyroid dysfunction.) Il. Surviving adult Rongelapese exposed to fallout. (Estimated dose: 175 rads external plus 160 rem internal irradiation.) Total - 34 1. Papillary carcinoma removed surgically at age 41. No recurrence. hormone therapy. Taking oral thyroid ° ot Small nodule at age 40 which disappeared under oral thyroid hormone therapy. 3. 1 This patient was exposed as an adult at the age of 22. The rough mass in one lobe of the thyroid found on physical examination proved to be an invasive adenoma involving the capsule of the thyroid, Since the lymph nodes were free of neoplastic cells only a subtotal thyroidectomy was performed, The patient is recovering satisfactorily with minimal signs of hypoparathyroidism. 1 pos ARCHIE 22.
