Abstract
Tuberous sclerosis complex (TSC) is an inherited neurocutaneous disease characterized by multiple hamartomas in multiple organs. However, there is limited evidence about neuroendocrine tumors (NETs) in patients with TSC, and routine screening of NETs is not recommended in the guidelines. Insulinomas are also an extremely rare disease. According to our knowledge, we presented the 10th TSC patient diagnosed with insulinoma in the literature. Thirty-two years old male patient diagnosed with TSC at the age of 27 due to typical skin findings, renal angiomyolipoma, history of infantile seizures, and cranial involvement was referred to our clinic. The main symptoms of the patient were palpitations, diaphoresis, confusion, and symptoms were improved after consuming sugary foods. Seventy-two hours fasting test was performed, and a low glucose level at 41 mg/dl, a high insülin level at 21.65 µIU/mL, and a high C-peptide level at 7.04 ng/mL were found at the 8th hour. In addition, a 12x7 mm lesion in the pancreatic tail was detected in abdominal imaging. Ga-68 PET-CT (gallium-68 positron emission tomography-computed tomography) detected an increased uptake of Ga-68 in the pancreatic tail. The patient underwent distal pancreatectomy, and pathological evaluation was consistent with an insulinoma. The patient's symptoms improved postoperatively. Since in nearly all TSC cases, as in our case, neuropsychiatric abnormalities, such as epilepsy, are one of the main disease manifestations, and these symptoms may be confused with the clinical manifestations of hypoglycemia in insulinoma. Therefore, patients with newly developed neurological symptoms and behavioral defects should be evaluated in terms of insulinoma.

Abstract
BACKGROUND Surgical treatment of Graves' disease (GD) has increased risk for bleeding, hypothyroidism and recurrent laryngeal nerve (RLN) palsy compared to other benign thyroidectomy indications. Nevertheless, it can be done safely in high volume centers. In some particular cases (i.e., anti-thyroid drug intolerance or thyrotoxicosis), urgent surgical treatment might be needed. In this study, we aimed to compare the complications of thyroidectomy in urgent and elective management of Graves' disease. METHODS The patients, who underwent total thyroidectomy due to Graves' disease between 2012-2019 (n=113) were evaluated retrospectively in terms of demographics, pre-operative laboratory results, management, hospital admissions, operative and post-operative short-term outcomes, morbidity and mortality. Patients who were hospitalized to endocrinology department due to uncontrollable hyperthyroidism and related complications and who were prepared for surgery with Lugol's solution, plasmapheresis and steroids were considered as Urgent Group (n=12). Remaining 101 patients who underwent elective surgery considered as Elective Group. Surgical short-term outcomes, morbidity and mortality rates were compared. RESULTS Of the 113 patients who were operated for GD, 92 were female and 21 were male. In urgently operated group, FT4 and FT3 levels were significantly higher (p<0.001 and p=0.001, respectively). There was no significant difference in transient or permanent hypocalcemia (p=0.821 and p=0.501, respectively), transient or permanent RLN palsy (p=0.356, p=0.634, respectively) and post-operative bleeding (p=0.338), between elective surgery and rapid optimization groups. CONCLUSION Emergency surgery for Graves' disease can be performed safely with the application of effective pre-operative treatment protocols.

Abstract
High stromal tumor-infiltrating lymphocytes (sTILs) in triple-negative breast cancer (TNBC) are associated with pathological complete response (pCR) after neoadjuvant chemotherapy (NAC). Histopathological assessment of sTILs in TNBC biopsies is characterized by substantial interobserver variability, but it is unknown whether this affects its association with pCR. Here, we aimed to investigate the degree of interobserver variability in an international study, and its impact on the relationship between sTILs and pCR. Forty pathologists assessed sTILs as a percentage in digitalized biopsy slides, originating from 41 TNBC patients who were treated with NAC followed by surgery. Pathological response was quantified by the MD Anderson Residual Cancer Burden (RCB) score. Intraclass correlation coefficients (ICCs) were calculated per pathologist duo and Bland-Altman plots were constructed. The relation between sTILs and pCR or RCB class was investigated. The ICCs ranged from -0.376 to 0.947 (mean: 0.659), indicating substantial interobserver variability. Nevertheless, high sTILs scores were significantly associated with pCR for 36 participants (90%), and with RCB class for eight participants (20%). Post hoc sTILs cutoffs at 20% and 40% resulted in variable associations with pCR. The sTILs in TNBC with RCB-II and RCB-III were intermediate to those of RCB-0 and RCB-I, with lowest sTILs observed in RCB-I. However, the limited number of RCB-I cases precludes any definite conclusions due to lack of power, and this observation therefore requires further investigation. In conclusion, sTILs are a robust marker for pCR at the group level. However, if sTILs are to be used to guide the NAC scheme for individual patients, the observed interobserver variability might substantially affect the chance of obtaining a pCR. Future studies should determine the 'ideal' sTILs threshold, and attempt to fine-tune the patient selection for sTILs-based de-escalation of NAC regimens. At present, there is insufficient evidence for robust and reproducible sTILs-guided therapeutic decisions.

Abstract
To examine the effects of multidisciplinary approach and adjunct methods, on the surgical strategy, complications and treatment success of parathyroid surgery.Patients, who were operated for primary hyperparathyroidism (n = 411) at our institution between 2012 and 2019 were reviewed retrospectively. Preoperative imaging studies, surgical method, additional diagnostic methods used during surgery, frozen section results, and histopathology findings, complications, persistence, and recurrence were examined.Localization was determined by first-line examinations in 79.9% (n = 348). Four-dimensional computed tomography was used with an 83.3% success rate. Lateralization success for angiographic selective venous sampling was 80.3% and exact localization success was 65.1%. Bilateral neck exploration was performed in 10.6% (n = 37) of the patients, and in the remaining 89.4% (n = 311), minimally invasive parathyroidectomy (MIP) was performed. While the complication rate was higher in the bilateral neck exploration group (P = .019), persistence and recurrence rates were similar between 2 groups. During the study period, annual case volume increased from 9 cases to 103 cases (P < .001) and the rate of MIP increased from 44.4% to 92.8% over the years (P < .001).Effective use of adjunct techniques has increased the rates of MIP. The multidisciplinary approach has also provided low complication rates with the increasing number of cases.

Abstract
Objective: Since the first definition of anal canal little has been discovered about the etiology of this rare condition. We present four asymptomatic cases of anal canal duplication with diverse clinical and surgical findings. Methods: A retrospective chart review was performed on four infants presenting with asymptomatic anal canal duplication, born between 2014 and 2016. Clinical characteristics and pathologic findings of patients either by radiological imaging or pathology were evaluated. The primary outcome measure was the complications. Results: All patients were followed-up with physical examination and ultrasound for a mean of 3.5±1.0 years, lastly seen at the beginning of 2018. The female to male ratio was 3:1. Duplicate anal canal length varied between 12-20mm, and two of the four patients had a presacral cystic mass confirmed as a tail gut cyst following surgery. At follow-up, none of the patients had developed symptoms related to anal canal duplication, regardless of whether they had surgical intervention. Conclusion: Though surgical management is the preferred treatment for anal canal duplication, it seems that patients who do not undergo surgery might remain free of symptoms, suggesting that surgical intervention may be unnecessary.

Abstract
Aim: To investigate the effect of tadalafil in rats administered with daily dutasteride.Methods: Twenty-four Sprague-Dawley male rats were allocated to three groups as control (group C), dutasteride (group D) and dutasteride plus tadalafil (group D + T). After a month of treatment, serum samples were obtained from rats to measure dihydrotestosterone and total testosterone. Nitric oxide (NO) synthase (NOS) immunoreactivity and levels of NOS enzyme isoforms, NO and cyclic guanosine monophosphate (cGMP) were evaluated in the harvested penile tissues. Also, corporal smooth muscle and collagen were examined.Results: Staining intensities of neuronal NOS and endothelial NOS were significantly lower in group D (p < .05). They were similar between group C and group D + T. Immunoreactivity of inducible NOS was observed higher in group D than group C (p = .01) whereas group D + T had the highest iNOS (p<.001). ELISA revealed similar outcomes in terms of NOS enzyme isoform levels. The mean of smooth muscle to collagen ratio was the lowest in group D (p < .001) and it was similar among group C and group D + T (p = .072). Group D had the lowest cGMP and NO levels (p < .05) and they did not differ between group C and group D + T (p>.05). Group D and group D + T had significantly decreased dihydrotestosterone and increased testosterone, compared to group C (p < .001). They were similar between group D and group D + T.Conclusion: Daily treatment with tadalafil improves dutasteride-induced changes in rat penis.

Abstract
PURPOSE The purpose of this study was to retrospectively investigate the response to trastuzumab in breast cancer patients in terms of the potential roles of several oncogenic pathways (phosphatase and tensin homolog (PTEN) and phosphatidylinositol 3-kinase (PI3K)) in relation to HER2 status. METHODS Paraffin-embedded primary tumor tissues of 100 HER2 positive metastatic breast cancer patients who received trastuzumab were analyzed with immunohistochemistry for p85 (PI3K) and PTEN. The relationship between variables was tested via chi-square, Fischer's exact test and Mann-Whitney U test, where appropriate. Progression-free survival (PFS) and overall survival (OS) were calculated with the Kaplan-Meier method and survival curves of subgroups were compared with the log-rank test. Results: The level of immunohistochemical expression of PI3K was 42%. Loss of PTEN was observed in 43% of the patients. PTEN-expressing tumors had statistically higher response rates for trastuzumab than tumors not-expressing PTEN (p=0.012). PI3K expression had no significant effect on trastuzumab response. Median PFS for PTEN-expressing and not-expressing tumors were 15.3 months (95% CI, 12.6-34) and 12.1 months (95% CI, 7.9-16.2), respectively (p=0.04). The level of PI3K expression had no effect on PFS and OS in our patient population. CONCLUSIONS Loss of PTEN predicted poorer response to trastuzumab treatment and shorter PFS but not OS. We could not find an effect of PI3K expression on the above-mentioned parameters.

Abstract
Spread through air spaces (STAS) have been recently recognized as a prognostic factor for adenocarcinoma and squamous cell carcinoma of the lung. Pulmonary neuroendocrine neoplasms (NENs) include tumors with different morphology and a heterogeneous clinical behavior. Among atypical carcinoids (ACs), new prognostic factors able to refine prognosis are needed. In the present study, a retrospective series of 91 surgically resected ACs was investigated, in parallel with 191 control cases of typical carcinoids (TCs) and of high-grade small- and large-cell neuroendocrine carcinomas, to assess the presence and potential prognostic role of STAS. STAS was defined by the presence of neoplastic nests or single cells in air spaces beyond the tumor edge. Clinicopathological parameters and survival were correlated by univariate and multivariate analyses. STAS was identified in 48% of ACs (44/91) compared to 20.5% of TCs and 71-88% of high-grade large- and small-cell carcinomas in the control group. In the carcinoid group, presence of STAS was significantly correlated with unfavorable parameters, such as high tumor stage, positive nodal status, high Ki-67 index, presence of angioinvasion, and with adverse disease outcome, shorter overall survival, and time to progression. In conclusion, the presence of STAS is an additional relevant adverse prognostic factor in pulmonary AC that currently has the most unpredictable outcome and the most controversial treatment strategy.

Abstract
Objective Paroxetine is a commonly prescribed SSRI that can impair erectile function in animal models via inhibition of nitric oxide synthase (NOS). Tadalafil potentiates nitric oxide (NO)-mediated responses in isolated trabecular smooth muscle and penile erection. The purpose of this study was to evaluate the impact of co-administering tadalafil with paroxetine on penile NOS levels in rats. Materials and Methods A total of 30 male Sprague-Dawley rats were divided into 3 groups as control (Group-C), paroxetine (Group-P) and paroxetine plus tadalafil (Group-P+T). After 28 days of treatment, rats were sacrificed and their penile tissues were harvested for analysis. NOS isoform protein levels and immunoreactivity scores of NOS were assessed. Statistical significance level was set at p<0.05. Results Neuronal NOS (nNOS) levels were significantly decreased in group-P, compared with group-C (p<0.001). In comparison, rats in group-P+T had significantly higher nNOS levels compared to group-P (p<0.001). Endothelial NOS (eNOS) and inducible NOS (iNOS) levels were significantly higher in group-P compared with group-C (p<0.01). The levels of eNOS and iNOS in group-P+T were similar to group-C. Conclusion Daily treatment with tadalafil prevented chronic paroxetine-induced changes in all three NOS isoform levels. Tadalafil treatment may therefore be a useful therapy in men with paroxetine-associated erectile dysfunction.

Abstract
The tendency of non-operative management of appendicitis let us explore the natural history of appendiceal carcinoids, compare them with appendicitis patients, and determine the possibility of deciding the extent of the surgery and post-operative follow-up on behalf of the intraoperative findings. A retrospective review was performed of patients with appendicitis between 2009 and 2017. Of 2781 patients, 10 (0.36%) were diagnosed with appendiceal carcinoids. Sixty percent were female with an average age of 13.10 ± 1.73. The mean tumor size was 0.97 ± 0.34 cm with 70% located at the tip. Majority had an insular pattern (n = 9), six had subserosal fat tissue invasion, one had extension to mesoappendix, one had vascular invasion, and two had lymphatic invasion. The average mitotic index was 3.20 ± 1.40/50HPF, and Ki 67 activity was 3 ± 1.7%. The mean follow-up period was 66.40 ± 25.92 months. Patients were further evaluated with ultrasonography (n = 10), CT (n = 3), and MRI (n = 10). Serum markers including chromogranin (n = 9), NSE (n = 6), and 5-HIAA (n = 6) were normal. None required further treatment and had any symptoms of carcinoid syndromes or recurrences post-operatively.Conclusion: Other than appendectomy, no additional surgery or follow-up is required in appendiceal carcinoids less than 1.5 cm in size, regardless of the lymphoid or vascular invasion. What is Known: • The treatment of patients with a 1-2-cm tumor is not clear in both the pediatric and adult populations, and additional resection is needed. • Patients are monitored post-operatively with radiological and/or biochemical testing. What is New: • Appendectomy is curative for tumors less than 2 cm. • No additional surgery or follow-up is required in appendiceal carcinoids less than 1.5 cm in size regardless of the lymphoid or vascular invasion.

Abstract
Tangier disease (TD) (OMIM#205400) is a rare cause of inherited metabolic neuropathies characterized by marked deficiency of high-density lipoproteins and accumulation of cholesterol esters in various tissue resulting from reverse cholesterol transport deficiency. We report a case of a patient with TD with multifocal demyelinating neuropathy with conduction block who presents with winging scapula, tongue, and asymmetric extremity weakness. We also present a review of all studies published from 1960 to 2017 regarding peripheral neuropathy in TD. Our search identified 54 patients with TD with peripheral neuropathy. Syringomyelia-like neuropathy subtype (52.4%) was more frequent than multifocal sensorial and motor neuropathy subtype (26.2%), focal neuropathy subtype (19.1%), and distal symmetric polyneuropathy subtype (2.4%). Splenomegaly was the most common (40.7%) clinical manifestation in these patients. The pattern of electrodiagnostic abnormalities are: (1) demyelinating abnormalities were more predominant in the upper extremities than in the lower extremities and (2) slowing of motor nerve conduction was more prominent in the intermediate segment than in distal nerve segments. The sural-sparing pattern was present in 34.6% and conduction block was present in 11.5% of the patients. Our literature review and our case showed the clinical spectrum of TD neuropathy is quite wide and that it should be considered in the differential diagnosis of non-uniform demyelinating neuropathies.

Abstract
We present the case of a 15-year-old girl who presented with an unusual grouping of lesions on her upper left leg. The lesions had been present since birth. The patient had five different types of lesions: 1) transparent grouped or scattered yellowish vesicles; 2) keratotic-surfaced, grouped dark-yellowish papules; 3) bright-red grouped papules; 4) keratotic-surfaced grouped dark-red papules; and 5) patchy, punctate, and erythematous red macules. All of the lesions were intertwined along the lines of Blaschko and were in the form of irregular serpiginous plaques. Histopathological examinations of the lesions showed three main histological features, and diagnoses of the lesions were made as lymphangioma circumscriptum, lymphangiokeratoma, and verrucous hemangioma. To the best of our knowledge, such intertwined lesions have never been reported in the literature. Hence, we suggest that the name of this unique combination of lesions be "congenital nevoid mixed hemato-lymphangio-keratoma serpiginosum."

Abstract
OBJECTIVE There is no other screening program close to the success rate of PAP test. Cervical cytology constitutes a large workload so that quality control in cervical cytology is important for the quality assurance of pathology laboratories. MATERIAL AND METHOD In this study, we collected the cervical cytology results from all over Turkey and discussed the parameters influencing the quality of the PAP test. The study was conducted with Turkish gynaecopathology working group and 38 centers (totally 45 hospitals) agreed to contribute from 24 different cities. The study was designed to cover the cervical cytology results during 2013. The results were evaluated from the data based on an online questionnaire. RESULTS The total number of Epithelial Cell Abnormality was 18,020 and the global Epithelial Cell Abnormality rate was 5.08% in the total 354,725 smears and ranging between 0.3% to 16.64% among centers. The Atypical squamous cells /Squamous intraepithelial lesion ratios changed within the range of 0.21-13.94 with an average of 2.61. When the centers were asked whether they performed quality assurance studies, only 14 out of 28 centers, which shared the information, had such a control study and some quality parameters were better in these centers. CONCLUSION There is an increase in the global Epithelial Cell Abnormality rate and there are great differences among centers. Quality control studies including the Atypical squamous cells/Squamous intraepithelial lesion ratio are important. Corrective and preventive action according to quality control parameters is a must. A cervical cytology subspecialist in every center can be utopic but a dedicated pathologist in the center is certainly needed.

Abstract
AIM To investigate the neuroprotective effect of chronic curcumin supplementation on the rat forebrain prior to ischemia and reperfusion. MATERIAL AND METHODS Forebrain ischemia was induced by bilateral common carotid artery occlusion for 1/2 hour, followed by reperfusion for 72 hours. Older rats were divided into five groups: Group I received 300 mg/kg oral curcumin for 21 days before ischemia and 300 mg/kg intraperitoneal curcumin after ischemia; Group II received 300 mg/kg intraperitoneal curcumin after ischemia; Group III received 300 mg/kg oral curcumin for 21 days before ischemia; Group IV had only ischemia; Group V was the sham-operated group. The forebrain was rapidly dissected for biochemical parameter assessment and histopathological examination. RESULTS In forebrain tissue, enzyme activities of superoxide dismutase, glutathione peroxidase, and catalase were significantly higher in Group I than Groups II or III (p < 0.05) while xanthine dehydrogenase and malondialdehyde enzyme activities and concentrations of interleukin-6 and TNF-alpha were significantly lower in Group I when compared to Groups II and III (p < 0.05). A significant reduction in neurological score was observed after 24 and 72 hours in the curcumin-treated groups compared with the ischemic group. We also found a marked reduction in apoptotic index after 72 hours in the groups receiving curcumin. Significantly more TUNEL-positive cells were observed in the ischemic group compared to those treated with curcumin. CONCLUSION We demonstrated the neuroprotective effect of chronic curcumin supplement on biochemical parameters, neurological scores and apoptosis following ischemia and reperfusion injury in rats.

Abstract
Homosalate (HMS) and 2-ethylhexyl 4-dimethylaminobenzoate (OD-PABA) are ultraviolet filters. We aimed to investigate the effects of dermal exposure to HMS and OD-PABA during the prenatal, lactation, and early infancy periods on pubertal development and thyroid function in male and female rats. The thyroid glands, uteri, testes, prostate glands, and seminal vesicles were excised and weighed, the reproductive organs were analyzed histologically, and the serum hormone levels were measured. In the prenatal period, the thyroxine (T4) levels increased in the female rats in the exposed groups ( p < 0.05); the thyroid weights, reproductive organ weights, and gonadal hormone levels were not altered. In males, the testosterone levels decreased ( p < 0.05), but the thyroid weights, T4 levels, prostate, and testis weights were not changed. In the lactation period, the weights of the thyroid glands increased in the exposed female groups ( p < 0.05), but the T4, gonadal hormone levels, and reproductive organ weights were not changed. In the males, the thyroid gland weights, T4 levels, reproductive organ weights, and gonadal hormone levels were not changed. During infancy, the thyroid gland weights increased in the female rats in the exposed groups ( p < 0.05), but the T4 levels, gonadal hormone levels, and reproductive organ weights were not affected. In the male rats in the exposed groups, the T4 levels were increased ( p < 0.05), but the thyroid and reproductive organ weights, gonadal hormone levels were not affected. Organ histopathology was not affected in all groups. HMS and OD-PABA do not have endocrine disruptor effects on thyroid function and the pubertal development of female and male rats.

Abstract
Mucocele Like Tumours (MLT) of the breast are quite rare neoplasms displaying a broad spectrum. These lesions were considered benign initially. But now, they are believed to be related to atypical ductal hyperplasia, ductal carcinoma, or mucinous carcinoma. Preoperative diagnosis in fine needle aspiration and core biopsy is difficult. We are reporting a case of mucocele like tumour with ductal carcinoma in situ and ductal carcinoma in a 71-year-old Turkish woman. The patient had a palpable mass in her left breast. Mammograpy showed ill defined and lobulated mass with widespread tiny microcalcifications. A few cells with sporadic nuclear atypia, were detected on FNAB (Fine Needle Aspiration Biopsy). Mastectomy was done on the left side because of the suspicion of malignancy as evident by mammograpy and FNAB. We examined adequate tissue samples from resection material. Histopathologic findings were consistent with MLT and microscopic focus of ductal carcinoma was also noted in mastectomy specimen. She is currently disease-free in the 118th month. We believe that our case will be the first patient from Turkey and will be added to the database as one of the longest term follow-up MLT cases reported. If a mucocele-like tumour is suspected in fine needle biopsy, surgical excision should be recommended and the specimen should be carefully evaluated to exclude the presence of ductal carcinoma in situ or carcinoma.

Abstract
The aims of this retrospective study were to consider the diagnostic role of dual-time 18F-fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET/CT) in detection of breast carcinoma and axillary lymph node (ALN) status and to evaluate the primary tumor 18F-FDG uptake pattern. Preoperative staging was performed by 18F-FDG PET/CT in 78 female patients with breast carcinoma. Conventional imaging results were evaluated by breast magnetic resonance imaging (MRI) of 79 lesions in 78 patients, bilateral mammography (MMG) of 40 lesions in 40 patients, and breast ultrasonography (USG) of 47 lesions in 46 patients. The primary tumor detection rate using 18F-FDG PET/CT was higher than those using MRI, USG, and MMG. The sensitivity and specificity of 18F-FDG PET/CT scans for detecting multifocality were higher than those of MRI. The specificity of ALN metastasis detection with MRI was higher than that with 18F-FDG PET/CT, but 18F-FDG PET/CT had higher sensitivity. Higher 18F-FDG uptake levels were detected in patients with ALN metastasis, histologic grade 3, estrogen-progesterone-negative receptor status, lymphatic invasion, and moderate to poor prognostic groups. There was no statistical difference for the retention index in categorical pathological parameters except for progesterone-negative status. In conclusion, 18F-FDG PET/CT scans may be a valuable imaging technique for evaluating primary tumor and axillary status in staging breast carcinoma and 18F-FDG uptake may be a prognostic factor that indicates aggressive tumor biology and poor prognosis. Dual-time imaging in breast carcinoma staging may not be used for predicting pathological criteria and the aggressiveness of primary lesions.

Abstract
Salivary gland small cell carcinoma (SGSmCC) is extremely rare, accounting for less than 1% of salivary gland tumors. A 42-year-old female patient came to the outpatient clinic due to a mass localized in the left submandibular space and that had been growing since 3-4 months. The fine needle aspiration cytology (FNAC) matched with small cell carcinoma (SmCC). As no other focus was detected by computerized tomography (CT), it was accepted as a primary neoplasm of the parotid gland. The histopathological assessment of the excised material and immunohistochemical staining demonstrated a neuroendocrine differentiation of SmCC. No recurrence was observed during the 54-month follow-up period. We believe this to be the second case of SmCC with neuroendocrine differantiation of the parotid glands reported in Turkısh medical literature and will be added to the english database as one of the favorable SmCC cases.

Abstract
Several types of suture materials are being used for the correction of penile curvature and this study was designed to compare histopathological changes on penile tissue among different suture materials. A total of 30 male Sprague-Dawley rats were divided into five groups and right cavernosal body was sutured with 5/0 sutures (ETB: polyethylene terephthalate; PRL: polypropylene; VCR: polyglactine; and PDS: polydioxanone). An identical needle (3/8-13 mm cutting) was passed through the cavernosal bodies in the sham group (SHAM). After 3 weeks, all rats were killed and penile tissues were examined to assess the level (0-3) of inflammation, granuloma formation and fibrosis. There was a statistically significant difference among five groups regarding inflammation, granuloma formation and fibrosis levels (P<0.01 for all). The histological changes in the PRL group were not different from the SHAM group. Although the levels of granulation and fibrosis in the PDS group were also similar to the SHAM group, inflammation level was significantly higher. The inflammation, granulation and fibrosis levels were the highest in the ETB group. VCR caused similar levels of granulation and fibrosis to ETB. In conclusion, PRL suture is associated with the least histopathological change in the penile tissue. PDS can theoretically be a reasonable alternative to PRL as it causes similar levels of granulation and fibrosis.

Abstract
BACKGROUND Salivary gland tumours, which account for approximately 3% of head-neck cancers, are a heterogeneous group and thus it is difficult to identify their epidemiological characteristics. The aim of this study is to determine demographic features and histopathologic distribution of parotid neoplasms in a large sample from Turkey. MATERIALS AND METHODS This study was conducted retrospectively on 136 parotidectomy materials from operations between May 2009-May 2013. Age, gender, tumor diameter, histopathological diagnosis and surgical margin status were recorded. RESULTS The benign cases were 112 (82.4%), while the malignancies were 24 (17.6%). The accuracy rate of FNAC was 91%. There were 46 (33.8%) male and 90 (66.2%) female patients. Female/ male ratio (M/F=0.5) was two, the Warthin (WT) tumor being more apparent in males (p<0.05). Pleomorphic adenoma (PA) was detected most frequently among benign pathologies at 61.6% (69/112), while the Warthin Tumor (WT) was detected as the second most frequent tumor at 20.5% (23/112). Mucoepidermoid carcinoma (MEC) and carcinoma ex pleomorphic adenoma (Ca ex PA) were detected at equal frequency at 20.8% (5/24) among malign tumors. These were followed by acinic cell carcinoma at 16.7% (4/24). While the surgical margin was positive in ten patients with malignant tumors (41.7%), all of the benign tumors were negative (p<0.01). No significant difference was detected in the age-gender of patients, tumor size and distribution of sites among benign and malignant groups (p>0.05). CONCLUSIONS Pleomorphic adenoma is the most frequently reported benign tumor almost in all global literature. Yet, the distribution of malignant tumors displays geographical differences. Based on these data, we believe that our findings will provide a significant contribution to future epidemiological studies. We think that it will be beneficial to generate awareness on parotid tumors and ensure a fight against smoking as with all head-neck cancers.

Abstract
Angiomatoid tumors of the thyroid gland are rare endocrine neoplasms, which exhibit an aggressive behavior. Angiosarcomas of the thyroid are generally reported from the European Alpine region and have a histogenesis that has been under debate for a number of years. The current study presents a rare case of angiosarcoma of the thyroid in a 62-year-old Turkish female. The patient had a 10-year history of goiter and was from the Black Sea region, an endemic goiter region of Turkey. The patient was not taking any medication at the time of admission and swelling had been observed on the right side of the neck throughout the previous few months. Thyroid function tests, which analyzed the levels of thyroid-stimulating hormone, thyroxine and triiodothyronine, were within the normal limits, however, the histopathological findings were consistent with an angiosarcoma of the thyroid. The patient rejected the complementary surgery and chemotherapy options, and is currently disease-free (as per the 15-month follow-up). The current study describes a case of angiosarcoma that was characterized by Weibel-Palade bodies, and light microscopy and immunohistochemical findings, as well as an endothelial origin, which was demonstrated via electron microscopy. To the best of our knowledge, this is the first reported case of angiosarcoma of the thyroid in a patient from Turkey to be validated by electron microscopy. Furthermore, this case is one of the few reported thyroid angiosarcoma cases in a non-Alpine region.

Abstract
Anaplastic thyroid carcinoma is a significantly fatal endocrine neoplasm, with an average survival time of 4–12 months following diagnosis. The present study reports the case of a 57-year-old male patient who presented to the Bağcılar Training and Research Hospital (Istanbul, Turkey) due to swelling in the neck and difficulty swallowing. The jugular mass biopsy results were consistent with a diagnosis of anaplastic thyroid cancer. The patient was regarded to have advanced-stage subcarinal, paratracheal, aortopulmonary, trancheobronchial and mediastinal lymphadenopathies and exhibited a good prognosis following chemotherapy. However, the patient succumbed one month later due to the emergence of diffuse skin lesions. The histopathological and immunohistochemical assessment of the skin biopsy displayed the characteristics of the underlying thyroid carcinoma.

Abstract
Gastrointestinal autonomic nerve tumour (GANT) is a rare mesenchymal neoplasm of the gastrointestinal tract arising from the neural plexus of the intestinal wall. Herein, we present a 70-year-old male patient presenting with a clinical picture of acute abdomen. Examination of the specimen obtained from the small bowel by means of complete resection revealed a relatively soft submucosal mass measuring 4.5 x 3 cm in size with spindle morphology and high mitotic activity (> 10 mitoses per 50 high-power fields). The tumour cells were strong positive for c-kit (CD117), S-100 protein and glial fibrillary acidic protein (GFAP), but did not harbour mutations in the c-kit and PDGFR genes. The diagnosis was based on light microscopy and immunohistochemical verification. We started tyrosine kinase inhibitor 400 mg/day. The patient is currently alive without metastasis at 28 months postoperatively. He is under close follow-up and survival data of the patient will be presented in the later studies.

Abstract
OBJECTIVES The purpose of this study was to evaluate whether the relative proportions of stromal to cellular components of pleomorphic adenomas have an effect on the shear elastic modulus determined by shear wave elastography (SWE). METHODS This study was approved by the Ethics Committee of our institution and performed between September 2011 and December 2012. Thirty-five patients who underwent surgery for a parotid mass were included in the study. The maximum shear elastic modulus of the mass was measured by SWE. Pleomorphic adenomas were histopathologically subdivided into stroma-poor, intermediate-stroma, and stroma-rich tumors based on the relative proportion of stromal to cellular components. RESULTS The maximum shear elastic modulus values of the pleomorphic adenomas ranged from 12.6 to 291.9 kPa (mean ± SD, 120.9 ± 92.8 kPa). The Friedman test revealed a statistically significant relationship between the stromal amount and maximum shear elastic modulus (P < .001). Stroma-poor adenomas (mean, 32.3 ± 27.7 kPa; range, 12.6-81.1 kPa) were softer on SWE than stroma-rich adenomas (mean, 174.1 ± 48.4 kPa; range, 92.7-217.2 kPa; P = .009). No such significant difference was detected between stroma-poor and intermediate-stroma tumors (mean, 146.3 ± 106.1 kPa; range, 19.1-291.9 kPa; P = .062) or between intermediate-stroma and stroma-rich tumors (P = .465). CONCLUSIONS Shear wave elastography depicts pleomorphic adenomas with a variable appearance, which is due to the relative proportions of stromal to cellular contents in the tumors.

Abstract
Idiopathic scrotal calcinosis is a rare and benign disease of the scrotum which is described in all age groups. It was initially first defined by Lewinski in 1883. Although many mechanisms have been proposed in the pathogenesis, underlying mechanisms are still controversial at the present time. Currently, the best therapeutic approach is the surgical removal of the scrotum without disrupting its integrity. Although it is indicated in literature that its recurrence is still controversial, we have observed relapse two times in our 41 year-old male patient following surgery at the 19th and 33rd months. We have confirmed recurrence with clinical and pathological assessments. Idiopathic scrotal calcinosis may recur both clinically and pathologically in the long-term follow up. Recurrence should be confirmed with post-surgical long-term follow up in larger series.

Abstract
First-derivative ultraviolet spectrophotometry and high-performance liquid chromatography (HPLC) were used to determine valsartan and hydrochlorothiazide simultaneously in combined pharmaceutical dosage forms. The derivative procedure was based on the linear relationship between the drug concentration and the first derivative amplitudes at 270.6 and 335 nm for valsartan and hydrochlorothiazide, respectively. The calibration graphs were linear in the range of 12.0-36.1 microg x ml(-1) for valsartan and 4.0-12.1 microg x ml(-1) for hydrochlorothiazide. Furthermore, a high- performance liquid chromatographic procedure with ultraviolet detection at 225 nm was developed for a comparison method. For the HPLC procedure, a reversed phase column with a mobile phase of 0.02 M phosphate buffer (pH 3.2)-acetonitrile (55: 45; v/v), was used to separate for valsartan and hydrochlorothiazide. The plot of peak area ratio of each drug to the internal standard versus the respective concentrations of valsartan and hydrochlorothiazide were found to be linear in the range of 0.06-1.8 and 0.07-0.5 microg x ml(-1), respectively. The proposed methods were successfully applied to the determination of these drugs in laboratory-prepared mixtures and commercial tablets.
