Thyroid Paraganglioma Diagnosed by Fine-Needle Aspiration Biopsy, Correlated With Histopathological Findings: Report of a Case.

Thyroid paragangliomas are rare neuroendocrine tumors. They are difficult to diagnosis by fine-needle aspiration biopsy (FNAB) and can be misdiagnosed as other types of thyroid disease. Here, we present an unusual case of primary thyroid paraganglioma diagnosed by FNAB. A 66-year-old woman presented with multinodular goiter. Ultrasound (US)-guided FNAB of the 3 cm nodule in the superior portion of the right lobe of the thyroid was performed. The cytological smears showed single cells or loose clusters of round to ovoid cells with oval granular nuclei. To differentiate between thyroid paraganglioma and other thyroid neoplasms, cell block material from the FNAB specimen was immunohistochemically stained with antibodies to thyroglobulin, calcitonin (CT), AE1-AE3, carcinoembryonic antigen (CEA), synaptophysin, chromogranin A (CH-A), neuron-specific enolase (NSE), thyroid transcription factor-1 (TTF-1), parathyroid hormone (PTH), and S-100. Immunohistochemical staining was positive for synaptophysin, CH-A, NSE, and S-100, and negative for thyroglobulin, CT, AE1-AE3, PTH, CEA, and TTF-1. Congo red staining was also negative. Paraganglioma and other neuroendocrine neoplasms were considered in the differential diagnosis. A total thyroidectomy was performed, and a final diagnosis of paraganglioma was made. Paraganglioma is a rare neuroendocrine tumor of the thyroid and should be considered in the differential diagnosis based on cytology of thyroid neuroendocrine tumors. Immunohistochemistry should be performed when making a diagnosis of thyroid paraganglioma, particularly when evaluating fine-needle aspiration smears. Diagn.

Significance of foamy histiocytes in cervical smears from postmenopausal women.

OBJECTIVE: To determine the significance of the presence of foamy histiocytes (FH) in postmenopausal cervicovaginal smears for the detection of endometrial carcinomas (EC). STUDY DESIGN: Endometrial sampling was performed over 6 months in 53 of 102 cases that presented with postmenopausal FH, benign endometrial cells (BEC), FH with BEC (FH + BEC), and atypical endometrial cells (AEC), resulting in a total of 41,150 cervicovaginal smears. The control group consisted of 58 cases with a cytologic diagnosis of a normal smear (NS). RESULTS: There were 0 (0%), 1 (4.54%), 2 (13.33%), 2 (33.33%), and 5 (50.00%) cases of EC diagnosed on histopathologic evaluation in patients with NS (n = 58), BEC (n = 22), FH (n = 15), FH + BEC (n = 6), and AEC (n = 10), respectively. The sensitivities and specificities of the cytologic diagnoses of FH, FH + BEC, and AEC for the detection of EC were 81.7 and 100%, 93.6 and 100%, and 92.1 and 100%, respectively. CONCLUSION: The cytologic diagnoses of FH and FH + BEC had reasonably high sensitivities and specificities for the diagnosis of EC by cervicovaginal smear. Additional studies are needed.

Clinical significance of benign endometrial cells found in papanicolaou tests of Turkish women aged 40 years and older.

BACKGROUND: Spontaneously exfoliated benign-appearing endometrial cells (BEC) on a Papanicolaou smear might indicate endometrial pathology in postmenopausal women, necessitating further investigation. A cut-off age of 40 years was included in the Bethesda System 2001 based on studies of clinical significance of endometrial cells in Pap smears in Western countries. AIMS: The purpose of this study was to determine the significance of age subgroup for women with a cytological diagnosis of BEC, regardless of menopausal status, in a retrospective cohort of Turkish women. MATERIALS AND METHODS: Between October 2006 and November 2011, 41 patients with a BEC diagnosis and 64 patients with a cytological diagnosis of normal smear (NS) were enrolled; regardless of menopausal status, these women were 40 years and older and for whom follow-up endometrial biopsies had been performed. RESULTS: On subsequent histopathologic evaluation, no malignant lesion was detected in women aged 40-50 years compared to three endometrioid-type adenocarcinomas in women older than 50 years with cytological diagnosis of BEC. There was a significant difference between women older than 50 years with cytologic diagnosis of BEC and NS in relation to premalignant lesions on histopathologic evaluation; however, this was not the case for women aged 40-50 years. CONCLUSIONS: According to our study, reporting BEC for women aged between 40 and 50 years has minor clinical significance but is significant for women older than 50 years, regardless of menopausal status. Larger sample size would be appropriate to confirm the results of the current study.

Endocervical glandular involvement, positive endocervical surgical margin and multicentricity are more often associated with high-grade than low-grade squamous intraepithelial lesion.

AIM: The aim of this study was to compare the relative frequencies of endocervical glandular involvement (EGI), multicentricity, positive endocervical surgical margins (ESM) and positive vaginal surgical margins (VSM), and adenocarcinoma in situ of the cervix (AIS) between high-grade and low-grade squamous intraepithelial lesions (HSIL and LSIL, respectively). MATERIAL AND METHODS: We identified 238 patients with squamous intraepithelial lesions/cervical intraepithelial neoplasia (CIN) who were treated by loop electrocautery excision (LEEP) or conventional cold-knife conization (CKC). A total of 223 (72 [32.3%] LSIL/CIN I; 85 [38.1%] HSIL/CIN II; 66 [29.6%] HSIL/CIN III; and 151 [67.7%], HSIL/CIN II + III) LEEP/CKC slides were histologically reviewed. RESULTS: The frequencies of EGI, positive ESM, and multicentricity were significantly higher in the HSIL/CIN II + III group than in the LSIL/CIN I group (P = 0.001, 0.001, and 0.025, respectively). Eighteen of the 72 (25%) LSIL/CIN I patients, 44 of the 85 (51.8%) HSIL/CIN II patients, and 60 of the 66 (90.9%) HSIL/CIN III patients (P = 0.001) showed EGI. In four of the 72 (5.6%) LSIL/CIN I patients, 18 of the 85 (21.2%) HSIL/CIN II patients, and 42 of the 66 (63.6%) HSIL/CIN III patients (P = 0.001), ESM was positive. Two of the 72 (2.8%) LSIL/CIN I patients, seven of the 85 (8.2%) HSIL/CIN II patients, and 11 of the 66 (16.7%) HSIL/CIN III patients (P = 0.016) were multicentric. CONCLUSION: The current study showed that EGI, positive ESM and multicentricity were more often associated with HSIL/CIN II + III than with LSIL/CIN I. Moreover, the frequencies of EGI, multicentricity, and positive ESM increased with increasing severity of the cervical lesion. This result may influence the preference for the type of surgical procedure used for patients with cytological diagnosis of HSIL.

Congenital central hypoventilation syndrome with hirschsprung's disease due to PHOX2B gene mutation in a Turkish infant.

The association of congenital central hypoventilation syndrome (also known as Ondine's curse) and Hirschsprung's disease is termed Haddad syndrome, which is an extremely rare disorder. Recent studies have described that the PHOX2B gene mutation was responsible for congenital central hypoventilation syndrome. We report a term newborn male infant with clinical manifestations of recurrent hypoventilation with hypercapnia and bowel obstructions. These clinical manifestations were compatible with congenital central hypoventilation syndrome and Hirschsprung's disease. PHOXB direct sequencing showed a heterozygous in-frame duplication of 21 bp leading to an expansion of +7 alanines within the 20 alanine stretch of the PHOX2B gene and confirmed our diagnosis. In addition to a high index of clinical suspicion, testing for PHOX2B mutation can assist iq the diagnosis of congenital central hypoventilation syndrome and in the prediction of disease progression. Infants presenting with congenital central hypoventilation syndrome should also be screened for Hirschsprung's disease.

Current prevalence of intestinal metaplasia and Helicobacter pylori infection in dyspeptic adult patients from Turkey.

BACKGROUND: The aim of this study was to investigate the prevalence of Helicobacter pylori (H. pylori) infection and intestinal metaplasia in adult dispeptic patients. (attending an endoscopy clinic at our training and referral hospital in Turkey). METHODOLOGY: A total of 3301 consecutive dyspeptic patients, with a mean age +/- SD of 45.97 +/- 15.15 years, had two antral and two corporal biopsies, during routine upper gastrointestinal endoscopy. Patients were divided into three groups according to age; 18-40 years old, 41-60 years old and over 60 years old. Histological specimens were examined and graded according to the Updated Sydney System for H. Pylori infection and intestinal metaplasia. RESULTS: H. pylori was established in 2353 patients (71.3%). Intestinal metaplasia was found in 586 patients (17.8%). Of these patients, 86% (n:504) had complete and 14% (n:82) had incomplete intestinal metaplasia. Frequency and severity of H. pylori infection decreased significiantly in the older group (p < 0.001). Patients with intestinal metaplasia were older (53.6 +/- 14.9 years) than patients without intestinal metaplasia (44.3 +/- 14.7 years) (p < 0.001). There was no statistically significant relationship between intestinal metaplasia and H. pylori presence (p > 0.05). Intestinal metaplasia was more prevalant in patients with mild infection (21.9%) than in patients without Helicobacter pylori infection (16.3%) or with moderate (16.2%) or severe infection (14.6%) (p < 0.01) CONCLUSION: H. pylori infection and density decreases, while the prevalence of intestinal metaplasia and incomplete intestinal metaplasia percentage increases in older dyspeptic patients. Mild H. Pylori colonisation could be a sign of intestinal metaplasia, especially in the elderly.

Orthopedic disability and socioemotional functioning.

BACKGROUND: The major aim of the study was to examine self-concept, emotional stability, and sociability of Turkish adolescents with orthopedic disability, and the links between these domains and sport participation. METHOD: Participants of the study were 95 students in grades 5-12 (mean age, 15.44 +/- 2.40 years). They were recruited from two boarding schools established for youth with orthopedic disabilities. Parents of the adolescents participated in the study by completing a form to provide information about the child, his/her condition (e.g. first appearance, severity, treatment), and the household in general. Adolescents filled in self-report scales that were developed to measure self-concept, emotional stability, and sociability. RESULTS: Hierarchical multiple regression indicated that regular engagement in sports significantly predicted self-concept of adolescents with orthopedic disability, and the predictive value of playing sport was significant even after differences in participant age, sex, and severity of the disability were taken into account. Emotional stability and sociability of adolescents with disability were predicted by sports playing but to a low degree. CONCLUSION: Study findings underline the importance of understanding social aspects of disability, and the positive association between playing sports and an individuals positive beliefs about oneself.

Congenital granular cell tumor.

Congenital granular cell tumor or congenital epulis is a rare benign soft tissue lesion in newborns. It usually arises from the mucosa of the gingiva, either from the maxillary or mandibular alveolar ridge, and may cause respiratory or feeding problems. We reported a case of a 1-hour-old female newborn with a congenital granular cell tumor in the anterior maxillary alveolar ridge. The lesion was causing a feeding problem and was excised under general anesthesia when the newborn was 1 day old.

Is it necessary to do retroperitoneal evaluation in borderline epithelial ovarian tumors?

OBJECTIVE: Borderline epithelial ovarian tumors have good prognosis without any adjuvant therapy. The advantage of aggressive surgical staging, especially retroperitoneal lymph node sampling is questionable in patients with borderline ovarian tumors. We designed this study to evaluate the necessity of retroperitoneal pelvic and para-aortic lymph node dissection in the treatment of borderline epithelial ovarian tumors. STUDY DESIGN: From 1998 to 2007, 57 women who were diagnosed with borderline epithelial ovarian tumor in our hospital were prospectively accrued and evaluated; 27 of them (47.3%) had full surgical staging procedure including para-aortic and pelvic node dissection. Student's t-test was used to compare follow-up times. RESULTS: Median follow-up time was 54.6 (12-96) months for all patients in the study. There was one recurrence of disease, which was in the complete staging group. Follow-up times of patients were not statistically different between lymph node evaluated and non-evaluated groups (p = 0.10). We did not find any metastasis in lymph nodes in 27 women who had complete surgical staging procedure. CONCLUSION: Patients with borderline epithelial tumors who had full surgical staging procedure do not have survival advantage over those who had no lymph node evaluation and yet were patients with malignant ovarian tumors.
