[Early recognition of C-cell carcinoma by family screening (author's transl)].

All available family members of five patients with C-cell carcinoma (medullary carcinoma of the thyroid) were tested for their basal serum-calcitonin level and after pentagastrin stimulation. In two females, aged 12 and 25 years, from two different families, serum-calcitonin was elevated, but only after repeated tests or after pentagastrin stimulation, to definitely abnormal levels. Neither had palpable thyroid nodules, lymph-adenopathy or diarrhoea. The thyroid scan was normal and there were no storage defects. But because of the family history and the elevated serum-calcitonin levels total thyroidectomy was performed in both. The specimens revealed multicentric, bilateral C-cell carcinomas. The serum-calcitonin concentration became completely normal postoperatively, so that one may justifiably speak of a curative effect of the thyroidectomy in these two instances of early diagnosis.

[The diagnostic significance of 99mTc-marked phosphate uptake in the soft tissues of the breast (author's transl)].

A patient with a right-sided carcinoma of the breast had a bone scintigram with 99mTc-methylendiphosphonate (99mTc-MDP), which showed intensive uptake in the abnormal breast; a year after mastectomy, similar high uptake of the drug was found in the remaining breast. The radiological findings indicated a fibrocystic mastopathy without evidence of malignancy in the left breast. A review of the literature suggested that uptake of osteotropic polyphosphate compounds in the breast was of considerable significance, indicating incipient or developing malignancy. A review of our own cases cast considerable doubt on this interpretation. It is probable that MDP uptake in the breast depends in part on the hormonal pattern and may occasionally be observed during oestrogen therapy in the male (eg. carcinoma of the prostate).

[Echographic localisation diagnosis of adenomas and hyperplasias of the parathyroid in primary hyperparathyroidism (author's transl)].

The results of echographic localization of adenomas and hyperplasia of the parathyroid glands in seven patients with primary hyperparathyroidism are reported. In four patients there was complete, and in three patients partial, agreement between the echographic diagnosis and the findings at surgery and histology. On the basis of this experience and the findings of other authors, echography must be regarded at present as the best method for pre-operative localization of adenomas and hyperplasia of the parathyroid gland.

[Approach to a differentiated recurrence prevention following struma surgery].

Changes of the pituitary-thyroid axis were studied in 70 patients (45 with euthyroid goiters, 25 with autonomous adenomas) preoperatively; over a 6-week postoperative interval without thyroid-hormone treatment; under T4 therapy increased stepwise and maintained for 1 year; and over a period of 12 weeks after its withdrawal. The postoperative thyrotropic function obviously depends on the preoperative condition and thereby on the quality of the remaining tissue as well as on the extent of the operation and thus the amount of remaining tissue. The frequency of a "prehypothyroid" status in the early postoperative course is high (77%) after bilateral resection for euthyroid goiter, but decreased 1 year after the operation (47%). After unilateral resection for euthyroid goiters and after bilateral and unilateral resection or enucleation for autonomous adenomas, the remaining tissue is for the most part sufficient to avoid increased pituitary stimulation. Prophylaxis of recurrent goiter with thyroid hormones could be prescribed individually on the basis of the postoperative function of the pituitary-thyroid axis.

Immunohistochemical reclassification of anaplastic carcinoma reveals small and giant cell lymphoma.

Thirty-one cases of thyroid malignancies which were originally classified as anaplastic carcinoma were reexamined immunohistochemically using PAP methods (peroxidase:antiperoxidase) for IgM, IgG, IgA, cytokeratin, calcitonin, lysozyme and alpha-1-antitrypsin. The reclassification results were compared with patient data such as clinical symptoms, treatment modalities, and clinical outcome. Postoperative radiotherapy was carried out in more than 80% of cases, chemotherapy in none. Seven of 31 tumors showed a positive staining for IgM (n = 4), IgG (n = 2), and IgA (n = 1) antibodies. All of these cases were negative for epithelial markers. Surprisingly, not only all small cell tumors (n = 3) but also 4 tissues with predominantly giant cell areas were among those reclassified as primary malignant lymphoma.
