BACKGROUND: Hyperparathyroidism is caused by parathyroid adenoma, hyperplasia or carcinoma. Parathyroid ade-nomas are the most common cause of parathyroid disease (85-88%) while atypical parathyroid adenomas and carcinomas are the least frequently seen parathyroid neoplasms which cause diagnostic difficulty. This series aims to identifiy lesions of parathyroidectomy specimens in our center and draw attention to borderline cases in between parathyroid adenoma and carcinoma.METHODS: The study included 638 parathyroidectomy materials diagnosed in our center between the years 2005 and 2016 and examined retrospectively, and all were included in the study.RESULTS: In all the 638 parathyroidectomy cases evaluated, 427 were diagnosed with adenoma, 117 with hyperplasia, 54 with normal parathyroid tissue, 32 with parathyroid neoplasm with uncertain malignant potential, 7 with parathyroid carcinoma and 1 with normal thyroid tissue.CONCLUSIONS: Parathyroid neoplasm with uncertain malignant potential defines cases with suspicious histopathological features of carcinoma but doesn't meet the criteria for parathyroid carcinoma. In our series, these cases are identified as atypical parathyroid adenoma. We present clinical and morphological features of our parathyroidectomy cases in an 11-year period and aim to raise concern about borderline cases in between adenoma and carcinoma. We think that such tumors, similar to the thyroid neoplasm classification, should be defined as parathyroid neoplasms with uncertain malignant potential and should be followed closely.
Primary thyroid lymphoma

Primary thyroid lymphoma is an uncommon thyroid malignancy. The treatment modalities significantly differ from other thyroid malignancies. Frequently it is accompanied by Hashimoto's thyroiditis, and it may be difficult to differentiate the two entities histologically. Patients typically present with suddenly growing mass in the thyroid gland. Discrimination between primary and secondary lymphoma is important due to variations in diagnostic tools, treatment modalities and prognosis. Surgery, chemotherapy, radiotherapy or combinations of these modalities may be applied in treatment. In this report, three cases with primary thyroid lymphoma in which three different treatment modalities have been applied are presented.
Use of Ligasure in thyroidectomy procedures: Results of a prospective comparative study

The thyroidectomy procedure requires many manupulations to achieve prompt hemostasis. This study assessed whether the outcomes of thyroidectomy using the Ligasure electrothermal vessel sealer were comparable with the conventional suture-ligation technique. We prospectively evaluated 58 consecutive patients who underwent thyroidectomy. Patients were allocated into two groups according to their preference. There were 30 patients in the Ligasure group and 28 patients in the conventional surgery group. Complications, operating time, and hospital stay were compared between the two groups and suture-ligations performed in the Ligasure group were recorded. The age, sex, and indications were similar in the two groups (p > 0.05). Complication rates and hospital stays did not show any difference according to the techniques used. Operating time was shorter in the hemithyroidectomy and total thyroidectomy patients of the Ligasure group (mean +/- SD: 77.38 +/- 13.71 vs. 99.80 +/- 12.53 minutes, p = 0.005; and 102.50 +/- 16.69 vs. 128.89 +/- 19.74 minutes, p = 0.010). The mean SD number of suture-ligations for each patient in the Ligasure group was 1.83 +/- 2.12. Thyroid surgery using the Ligasure is safe, and its complication rates are comparable to these found with the conventional surgical technique. Use of the Ligasure during hemithyroidectomy and total tyhroidectomy operations provides a significantly shorter operating time.
