Guided intraoperative scintigraphic tumor targeting of metastatic cervical lymph nodes in patients with differentiated thyroid cancer: a single-center report.

OBJECTIVE: Our aim was to present our experiences related to performing neck surgery using the guided intraoperative scintigraphic tumor targeting (GOSTT) procedure for patients who had locally recurrent or persistent differentiated thyroid cancer (DTC) and who had undergone previous thyroid surgery. SUBJECTS AND METHODS: We retrospectively evaluated 11 patients who had locally recurrent or persistent DTC, who had undergone previous surgery, and for whom reoperation was planned for metastatic cervical lymph nodes (LNs). We performed the neck surgery using the GOSTT procedure on all patients and at a single academic institution. RESULTS: The 11 patients had a total of 26 LNs, as marked with a radiotracer, and those LNs' mean size was 14.7 ± 8.2 mm (range: 5-34 mm). Histopathological examinations revealed DTC metastasis in all 26 of the preoperatively marked LNs. Of the 11 patients, only one needed a reoperation in the neck; she had another successful surgery (also using the GOSTT procedure). In the evaluation of the patients' final status, all were disease-free in their necks. There also were no GOSTT-associated postoperative complications. CONCLUSION: The GOSTT procedure is a useful, successful, inexpensive, and comfortable procedure for marking and mapping metastatic LNs, especially in DTC patients who have undergone previous surgery.

A Case Report of Bilateral Adrenal Sarcomatoid Carcinoma.

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Sarcomatoid adrenal carcinoma is even more aggressive type of ACC. Bilateral malignant adrenal tumors are extremely rare except for those that represent metastasis from an extra-adrenal organ. Here we report a 53-year-old woman who presented with abdominal pain and weight loss. Abdominal computed tomography revealed bilateral adrenal masses and a mass in her liver. Surgical specimens showed pleomorphic tumor cells with epithelial and spindle cell morphology and immunohistochemical staining was compatible with sarcomatoid carcinoma. Sarcomatoid adrenal carcinoma should be kept in mind during the management of bilateral adrenal masses.

Hyperparathyroid crisis presenting with hyperemesis gravidarum.

PURPOSE: Primary hyperparathyroidism during pregnancy is a rare condition, and the diagnosis may be confounded by pregnancy related conditions. Since the appropriate management reduces the maternal and fetal complications; differential diagnosis becomes quite crucial. METHOD: Clinical course of a patient with hyperparathyroid crisis will be discussed with the review of the literature. A 22-year- old, (gravida 2, para 1) woman was presented with hyperparathyroid crisis at the 11th weeks' gestation. She was hospitalized twice due to hyperemesis gravidarum. When she was admitted to the hospital for the third time due to increased vomiting and weight-loss, serum biochemistry panel was performed and it revealed severe hypercalcemia that serum Ca was 17.59 mg/dl, and she was referred to our hospital as parathyroid crisis. Maternal hypercalcemia was resolved after urgent parathyroidectomy. She was diagnosed as preeclampsia at the 30 weeks' gestation and delivered a male infant weighing 1,090 g at 33 weeks' gestation with APGAR scores 6 at 1 min, and 7 at min 5, without evidence of neonatal hypocalcemia or tetany. RESULTS: Urgent parathyroidectomy is the definite treatment in symptomatic patients with hyperparathyroidism during pregnancy. Resolving maternal hypercalcemia prevents neonatal tetany and hypocalcemia. CONCLUSION: Hyperemesis may lead to hypercalcemic crisis in patients with hyperparathyroidism, so serum Ca level should be checked in patients with hyperemesis gravidarum especially who detoriate rapidly. Although they share some common pathogenetic mechanisms, there is not enough evidence for attributing preeclampsia to primary hyperparathyroidism.
