RESUMEN

BACKGROUND AND OBJECTIVES: To identify the relation between the preservation status of the parathyroid glands and the risk of hypoparathyroidism after total thyroidectomy and central lymph node dissection in papillary thyroid carcinoma. SUBJECTS AND METHOD: A retrospective review was carried out for the medical records of 63 patients with papillary thyroid carcinoma (PTC), who satisfied our inclusion criteria and received treatment at the Department of Otolaryngology-Head and Neck Surgery, Hospital from May 2010 to December 2011. Patients with PTC who underwent total thyroidectomy with central lymph node dissection (CLND) were included and grouped according to the number of preserved parathyroid glands as follows: Group 1 (with four intact glands), Group 2 (three intact glands), Group 3 (less than two intact glands). The total and ionized serum calcium and intact parathyroid hormone levels of each group were monitored after the surgery. Patients with postoperative symptomatic hypocalcemia were considered to have postoperative hypoparathyroidism and received calcium/vitamin D therapy. The hypoparathyroidism was considered to be permanent when calcium/vitamin D therapy was still required six months after surgery. RESULTS: Out of 63 cases of total thyroidectomy with CLND, 31 (49.2%) showed postoperative hypoparathyroidism as demonstrated by laboratory findings. Permanent hypoparathyroidism, however, was not observed in these cases. The development of hypoparathyroidism was not significantly related with the number of preserved parathyroid glands. CONCLUSION: To prevent postoperative hypoparathyroidism following total thyroidectomy and CLND, at least two parathyroid glands should be preserved in situ with an intact blood supply in order to prevent permanent hypoparathyroidism after the surgery.

RESUMEN

Sarcomatoid carcinoma is a rare biphasic tumor characterized by a combination of malignant epithelial and mesenchymal cells. The known characteristics are rapid growth, a high recurrence rate, and an extremely poor prognosis. This type of tumor is also uncommon but has been found in several anantomical sites: female genital tract, skin, gastro-intestinal tract, heptatobiliary system, head, neck, respiratory system, and urinary tract. However, solitary sarcomatoid carcinoma of the neck area is rare. Here, we report a patient who presented an extremely aggressive solitary sarcomatoid carcinoma of the neck.
