Abstract

A 55-year old female patient on long-term hemodialysis began to suffer from pain in her knees and ankles. An ultrasonographic study showed enlargement of all four parathyroid glands. Serum parathyroid hormone and calcium levels were increased. Parathyroidectomy was performed. The right superior gland was enlarged and adherent to surrounding tissues. The other three glands were slightly enlarged. Histologically, the largest gland was a parathyroid carcinoma because capsular and vascular invasion were observed. To our knowledge, there have been only 13 cases of parathyroid carcinomas arising in patients with chronic renal failure reported in the English literature. To evaluate the characteristics of this tumor, we measured nuclear DNA and protein content using stains for HP (hematoporphyrin)/DAPI (4,6-diamidino-2-phenylindole dihydroporphyrin chloride). The nuclear DNA pattern was typically diploid or tetraploid. The cellular protein content was similar to that seen in the controls. The discrepancy between the histology, indicative of malignancy and the cytofluorometrical findings show that it is difficult to determine the prognosis for patients with secondary hyperparathyroidism and parathyroid carcinomas solely from the results of tumor DNA cytometry.
