Primary extramedullary plasmacytoma (PEMP) of the thyroid is rare. Only nine patients with PEMP of the thyroid have been reported in Japan to date. We describe an additional autopsy case with PEMP of the thyroid and review of the literature in Japan. A 67-year-old women complaining of swelling of the anterior neck exhibited thin scalp hair, edematous face and a giant, hard, nodular goiter. Laboratory examination showed elevated levels of ESR, collagenous reaction, gammaglobulin, and a M-bow of the IgG-k type in immunoelectrophoresis. No Bence-Jones protein was found in the urine. Thyroid function test revealed a subclinically hypothyroid state, showing a T3 of 1.32 ng/ml, a T4 of 10.0 micrograms/dl, a TSH of 23.4 microU/ml and positive thyroid antibodies. The scintigram and the CT scan of the thyroid showed deviation of the trachea by the thyroid tumor and calcification within homogeneous thyroid gland. She underwent total thyroidectomy because of suspected malignancy. The histological examination of the removed thyroid weighing 117gr revealed a proliferation of plasma cells and lymphocytes and small amounts of atrophied thyroid follicles. The immunohistological examination of the removed thyroid showed the monoclonality to IgG-k chain. Plasma cells were stainable with methylgreenpyronine. Twenty-six months after thyroidectomy, she died due to progressive emaciation, anemia, hypoalbuminemia and ascites. Postmortem examination revealed widespread metastasized plasma cell tumors in the liver, intestine, spleen and mesentery with ischemic changes in heart and kidney. Based on our autopsy case and the nine cases reported in Japan, clinical and histological characteristics of PEMP of the thyroid were discussed.

Treatment of adult rats for 28 days with 0.50% of simmondsin induced a reduction of food intake of about 40%. The degree of emaciation was the same in simmondsin treated rats (SM) and pair-fed controls (PF). Diurnal variation of plasma thyroid hormone concentrations was determined. The reduction in food intake induced a decrease of mean 24 h plasma T3, T4 and TSH concentrations. Plasma T4 concentrations were decreased more in SM than in PF at almost all times of the day. No difference was seen between SM and PF for plasma T3 and TSH concentrations. Liver outer ring deiodinating activity (type I) remained unchanged compared to controls in PF and SM, but liver inner ring deiodinating activity (type III) was increased 4 fold in both SM and PF. It was concluded that the food intake reduction induced by simmondsin produced a decrease in plasma TSH concentrations which in turn reduced plasma T4 concentrations. Decreased plasma T4 concentrations together with an increased degradation of plasma T3 resulted in lower plasma T3 concentrations.

Characterization of elderly (> or = 65) patients with Graves' disease (GD) was discussed. Emaciation was the symptom that was most frequently found in elderly patients. The presence of goiter, exophthalmos and increased appetite decreased with age, while weight loss, anorexia and arrhythmia increased. Elderly patients often have serious complications such as congestive heart failure and atrial fibrillation. Serum levels of free T3, free T4 and TSH receptor antibodies were significantly lower in elderly patients. In addition to fewer clinical signs and symptoms of GD in elderly patients, prominent cardiac or gastrointestinal findings may make the diagnosis more difficult. Elderly GD patients should be treated with antithyroid drugs. Radioiodine therapy may be considered after normalization of serum thyroid hormone levels.

In this report, an extremely rare case of pediatric thyrotropin-secreting pituitary macroadenoma (TSHoma) is described. An 8-year-old boy, complaining of unsteady gait, was suspected of endocrinopathy because of emaciation and muscle weakness of the legs. Endocrinological work-up established a diagnosis of hyperthyroidism due to syndrome of inappropriate secretion of TSH. Magnetic resonance imaging showed a pituitary macroadenoma with suprasellar and sphenoidal extension without cavernous sinus invasion. He underwent an endoscopic endonasal transsphenoidal adenomectory due to the diagnosis of TSHoma. The adenoma was soft and it was totally removed. Histopathological staining confirmed diagnosis of TSHoma. Postoperative evaluation revealed a subnormal level of TSH (from 13-21 to 0.03 micro U/ml), normalization of alpha-subunit (from 10.0 to 0.09 ng/ml), and as a result, hypothyroidism. The boy left the hospital with oral levothyroxine that continued until 12 months of discharge. The present 8-year-old case is the youngest case to the best of our knowledge based on a bibliographical search. Reasons for endocrinological remission following adenomectomy are (1) correct diagnosis without delay: lack of cavernous sinus invasion, (2) soft and non-fibrous adenoma tissue, and (3) endoscopic technique with wide vision and illumination: safe even for a 8-year-old child. Early recognition/detection and pituitary-conserving adenomectomy can cure TSHoma and avoid long-term medical therapy and/or irradiation, which contribute to the best interests of patients with TSHoma.
