    Warthin-like Tumor of the Thyroid - A Rare Variant of Papillary Thyroid Cancer: Report of Two Cases

    Acta Endo (Buc) 2014 10(1): 150-154 doi: 10.4183/aeb.2014.150

    Background. Warthin-like tumor of the thyroid (WALTT) is a very rare variant of papillary thyroid cancer.We want to draw attention to this rare condition by reporting two cases. Patient reports. Patient 1 was a 24 year-old woman presented with 14×12 mm solid nodule on the left lobe of the thyroid gland. Fine needle aspiration biopsy of the nodule was reported as suspicious for papillary thyroid carcinoma. Patient 2 was a 40 year-old woman who had multinodular thyroid gland with a 31×26 mm major nodule on the left lobe. On fine neddle aspiration, cytologic findings were consistent with papillary thyroid carcinoma. Both underwent total thyroidectomy and histological examination of the cases revealed Warthin-like tumor of the thyroid. Summary and conclusion. We report two patients with WALTT. This rare variant of papillary thyroid cancinoma has four main histologic criteria: papillary architecture, oxyphilic cytoplasmic changes, papillary nuclear features and dense lymphoid infiltrate. WALTT can be distinguished from other aggressive variants with these distinct histological features. Since variants show different clinical behaviour, classification of these might be helpful to predict patient prognosis.

    Thyroid Malignancy Risk of Incidental Thyroid Nodules in Patients with Non-Thyroid Cancer

    Acta Endo (Buc) 2016 12(2): 185-190 doi: 10.4183/aeb.2016.185

    Context. Thyroid incidentaloma is a common disorder in endocrinology practice. Current literature regarding the risk of thyroid cancer in incidentalomas found in patients with non-thyroid cancer is limited. Objective. The aim of the present study was to investigate the frequency of thyroid malignancy in thyroid incidentalomas detected in patients with non-thyroid cancer. Design. Case control study. Subjects and Methods. The database of 287 thyroid nodules from 161 patients with a history of nonthyroid cancer followed between 2008 and 2014 were retrospectively evaluated. Results. From 287 thyroid nodules, 69.7 % had a benign final cytology. Thyroid cancer detected in one nodule while follicular neoplasia detected in 4 nodules, atypia of unknown significance (AUS) detected in 10 nodules, Hurthle cell neoplasia detected in 5 nodules and suspicious for malignancy detected in 6 nodules according to fine needle aspiration biopsy results. Metastasis of the non-thyroid cancer to the thyroid gland was detected in 4 nodules. Twenty seven nodules from 15 patients were removed with surgery. There were 3 malignant nodules found after surgery (1 papillary, 1 follicular and 1 medullary cancer). In addition to these three thyroid cancers, two patients with benign nodules had co-incidental thyroid cancer detected after surgery. Finally, 11.1 % of thyroid nodules which underwent thyroid surgery had malignant histopathology except for co-incidental and metastatic cancers. Conclusions. The frequency of thyroid malignancy seems not to be substantially increased in incidental thyroid nodules detected in patients with non-thyroid cancer when these patients were evaluated in nodule-based approach.

    Disease Control Using Various Treatment Modalities in Acromegaly

    Acta Endo (Buc) 2011 7(4): 491-502 doi: 10.4183/aeb.2011.491

    Aim. This study aimed to investigate the clinical presentation and treatment outcomes of newly diagnosed acromegaly patients treated with various combinations\r\nof treatment modalities.\r\nMaterials and Methods. Eighty-four acromegaly patients (42 female, 42 male, mean age 40.29?13.32 y), followed and\r\ntreated between 2000 and 2010 were included. Data on patient demographics, delay between onset of symptoms and the\r\ndiagnosis, details of treatments, and treatment- or disease-related morbidity and mortality were collected and analyzed. The median delay time for diagnosis was 60.71 ? 56.19 months. Patients received various combinations of surgery, gamma knife radiotherapy or conventional radiotherapy,\r\nlong acting somatostatin analogue, and dopamine agonist.\r\nResults. After ten years of treatment, median GH and IGF-1 values decreased from 13.7 ng/mL (IQR: 5.3- 34) to 1.04\r\nng/mL (IQR: 0.52-2.7) and from 600 &#956;g/L (IQR: 460.5-787.5) to 194 &#956;g/L (IQR :157-356), respectively (p<0.0001).\r\nMedian GH during 75 g oral glucose tolerance test (OGTT) decreased from 4.35 ng/mL (IQR: 1.87-13.15) to 1.40 ng/mL\r\n(IQR: 0.60-3.40) (p<0.0001). Fifty patients (59.5%) were in remission according to IGF-1 values and 52 patients (62 %) were cured according to nadir GH during OGTT respectively. The mortality rate was 5.9%.\r\nIn conclusion. Strict biochemical control following appropriate intervention significantly reduces both morbidity and mortality in acromegaly patients.

    Review of Thyroid Cytology and Histology Slides in a Tertiary Centre Leads to a Change in Planned Surgical Treatment for Patients with Thyroid Nodules

    Acta Endo (Buc) 2011 7(4): 523-528 doi: 10.4183/aeb.2011.523

    Aim. Histology and cytology consultations of thyroid fine needle aspiration biopsy (FNAB) of thyroidectomy specimens can change management of the patient. We aimed to determine compliance rates of pathology results between urban centers and a tertiary institution and its impact on patient management.\r\nMethods. This retrospective study includes 101 patients, who were referred to our center, between January 2008 and December 2008. After admission, all FNAB or thyroidectomy specimens of patients managed elsewhere were consulted by the pathology department. Comparison of FNAB and histology reports of our institution and the medical centers elsewhere had been carried out.\r\nResults. A total of 76% concordance rate was found between the FNAB results of other centers and consultation results. The highest concordance was observed in the malignant cytology group (77%). The cytological or histological outcomes of 24 (23.7%) patients were interpreted differently. After second opinion, patient management\r\nchanged in 21 of the 101 patients.\r\nConclusion. Since FNAB results can change the type of surgical treatment and the management plan, the results especially reported as suspicious may need a second\r\nopinion. We suggest that cytology or histology results of thyroid patients referred to tertiary centers for further evaluation and treatment should always be reviewed.

    Hypocalcemia and Hypomagnesemia Due to Long Term Omeprazole Treatment

    Acta Endo (Buc) 2014 10(4): 699-704 doi: 10.4183/aeb.2014.699

    Context. This is the first case of proton pump induced hypomagnesemia and hypocalcemia, accompanied with increased parathormone levels. Objective. The proton pump inhibitors are widely used medications. They are considered safe, however, they have some side effects. One of these side effects is hypomagnesemia. Here we report a case with severe hypocalcemia and hypomagnesemia due to long term proton pump inhibitor. Case. A 73 years old woman, admitted to emergency room due to generalized tonic-clonic seizures. She had a previous history of muscle cramps and paresthesia for 4 months. She had a medical history of peptic ulcer and she was taking omeprazole for 7 years. Her laboratory evaluation showed marked hypomagnesemia [0.5 mg/dL (normal: 1.7-2.55 mg/dL)] and hypocalcemia [6.2 mg/dL (8.8-10.2 mg/ dL)] with extremely low urinary calcium (Ca) and magnesium (Mg) excretion [0.01 gr/24 h (normal:0.05-0.3 gr/24 h), <1.22 mg/24 h (normal: 9.7-12.20) respectively]. Her vitamin D level was normal [35 ng/ mL (normal:30-80 ng/mL)] and PTH was increased [129 pg/mL (normal: 15-65 pg/ mL)] in accordance with the secondary hyperparathyroidism. Symptoms resolved with the intravenous supplementation of calcium gluconate and magnesium sulphate. However, despite high levels of oral replacement, Mg levels remained low. With omission of omeprazole two months after the admission, her ion levels returned to normal without any replacement. Conclusion. Especially elderly patients with long term proton pump inhibitor therapy, should be monitored for the symptoms of hypocalcemia and hypomagnesemia.
