The thyroid carcinoma is rare in children and the optimal management is rather controversial. We report a case of a 7-year-old boy who had right neck masses and proved to be papillary thyroid carcinoma after near-total thyroidectomy. Post-operative 20 mCi radioiodine-131 (I-131) ablation scan, lung metastasis was suspected but the chest X ray was normal. After being lost to follow up for 4 years, the patient returned with the complaints of cough; the chest X ray was still normal. He then received 5 treatment with low dose (30 mCi) I-131 therapy and continued thyroxine replacement. Progressive decrease both of the thyroglobulin level and the intensity of radioactivity of lung were noted. After a total doses of 193 mCi I-131 therapy, neither pulmonary fibrosis nor bone marrow suppression was seen. Although the low dose (< or = 30 mCi) I-131 therapy was recommended, it was limited for the ablation therapy of the remnant thyroid tissue. Upon consideration of economics and the convenience of not being admitted to the isolation room, the low dose I-131 therapy seems feasible for children with thyroid carcinoma with systemic disease. However, the long term efficacy needs further evaluation.

A 56-year-old woman was initially seen in March 1998 with a complaint of back pain. Her thyroid gland was swollen and the level of TSH was elevated at 10 microU/ml. Chronic thyroiditis with hypothyroidism was diagnosed. Negative reactions were obtained for both anti-thyroglobulin and anti-thyroid peroxidase antibodies. Daily treatment with thyroxine 50 mg was started. A cough developed in August 1998, and her chest radiographs revealed multiple bilateral consolidation shadows. A transbronchial lung biopsy specimen demonstrated mononuclear cells infiltration in the alveolar septa with fibrosis, consistent with nonspecific interstitial pneumonia (NSIP). There were no findings clinically or serologically suggestive of collagen-vascular diseases. Ultimately interstitial pneumonia compatible with the NSIP pattern in association with chronic thyroiditis was diagnosed. Oral prednisolone (30 mg/day) and azathioprine (50 mg/day) administration was initiated. The cough and the shadows on the chest radiographs improved. However, one year after completion of the treatment, interstitial pneumonia recurred. Retreatment with prednisolone and azathioprine has resulted in its improvement.

Three cases of primary pulmonary papillary carcinomas with a prominent "morular" component involved 2 women and 1 man (age range, 25-68 years). The patients had symptoms related to the pulmonary mass, including chest pain, cough, and dyspnea. Radiographic evaluation of the thorax revealed the presence of a pulmonary mass. Surgical biopsies were obtained and reported as non-small cell carcinoma. All patients underwent lobectomy. Two tumors were located in the right upper lobe and 1 in the left upper lobe. The tumors were soft, white to tan, without evidence of necrosis or hemorrhage, and 2.5 to 3.5 cm in greatest diameter. The tumors were characterized predominantly by papillary architecture containing numerous "morules" composed of spindle cells without nuclear atypia or mitotic activity. Some morules were floating freely within papillary spaces; others seemed to detach from the papillary structures. Immunohistochemical studies of 2 tumors showed positivity for thyroid transcription factor-1, keratin, and carcinoembryonic antigen and negativity for thyroglobulin. The morules showed positive thyroid transcription factor-1 staining, weak keratin staining, and negative staining for smooth muscle actin, desmin, and HMB-45. These cases highlight an unusual phenomenon, that of primary papillary carcinomas of the lung with a prominent morular component.

Distant metastasis of rare malignant struma ovarii (MSO) has been reported for cases associated with papillary thyroid cancer but few with follicular thyroid cancer. A 38-yr-old woman with struma ovarii that was initially diagnosed as "benign" presented with pulmonary metastasis and coughing 17 yr later. The lungs lesions were confirmed to be follicular thyroid cancer by biopsy. Rereview of the initial surgical ovary specimens confirmed the condition to be MSO with follicular thyroid cancer. The patient was treated with total thyroidectomy, which showed no thyroid malignancy, followed by (131)I (iodine-131) treatments. Dramatic reduction was observed in both the stimulated thyroglobulin level and the size of the pulmonary metastases over 1 yr. During the following 3-yr follow-up, the patient remained clinically well, with undetectable thyroglobulin (<1 ng/mL) and small stable pulmonary lesions. This is an exceedingly rare case of MSO with follicular thyroid cancer metastasized to the lungs presenting with a late onset but a fortunate excellent response to multidiscipline treatments. It is advisable that struma ovarii be carefully examined to avoid missing malignancy and patients be clinically followed up even with a benign initial diagnosis.
