Objective: The aim of this study is to evaluate the perioperative and postoperative follow-up results of patients operated for a parotid mass.

Materials and Methods: A total of 66 patients who were operated between 2000 and 2011, were evaluated retrospectively.

Results: The mean age of the patients was 48,6. On the basis of post-operative histopathologic assessement, 61 of the cases were found to be primary benign, 3 of the cases  primary malignant and 2 of the cases secondary malignant. Pleomorphic adenoma was the most common in primary benign tumors group with 29 cases, Warthin tumors were in the second place with 14 cases. Adenoid cystic carcinoma, adenocarcinoma and expleomorphic adenoma were observed as primary malignant tumors. Both of the seconder malignant tumors were metastasis of squamous cell carcinoma. Sensitivity and specifity of the preoperative fine needle aspiration biopsy in the benign-malignant differentiation were found as 60 % and 96 %, respectively. Superfacial parotidectomy, total parotidectomy and radical parotidectomy were used as surgical procedures. In addition to this procedure, neck dissection was performed in several cases. The most frequent complication was temporary facial nerve paresis.

Conclusion: Fine needle aspiration biopsy is an effective diagnostic procedure for the benign-malignant differentiation of the parotid tumors. Superfacial parotidectomy is an adequate and efficient surgical procedure for the benign parotid tumors and complication risk is considerably low when applied carefully. For malignant tumors, superfacial, total or radical parotidectomy should be performed and when necessary, neck dissection and postoperative radiotherapy should be added to the treatment.

Aim: Gastric cancer is one of the leading causes of cancer-related deaths. Tumor budding has been
shown to be a prognostic factor in many cancers. In this study, we aimed to evaluate the prognostic
significance of tumor budding in intestinal-type gastric adenoc arcinoma.
Patients and Methods: A total of 152 cases diagnosed as intestinal type gastric adenocarcinoma in
the Pathology Clinic between 2015 and 2021 were included in the study. Tumor budding was grouped
as low, medium and high. Hematoxylin and eosin-stained slides were re-evaluated in terms of tumor
differentiation, lymphovascular invasion (LVI), perineural invasion (PNI), lymph node involvement, depth
of invasion (pT) and tumor budding.
Results: Tumor budding was low in 30.9% (n=47) of the subjects included in the study, moderate in 37.5%
(n=57) and high in 31.4% (n=48). Statistically, as tumor budding increased, tumor size increased (p<0,05),
follow-up times were shortened, survival time (p<0,05), and tumor differentiation (p<0,05) decreased. A
statistically significant correlation was observed between tumor budding and LVI (p<0,05), PNI (p<0,05),
pT(p<0,05), lymph node involvement(p<0,05), and mortality of the cases (p<0,05). No statistically
significant correlation was observed between tumor budding and gender, age, tumor localization and
operation type (p>0.05).
Conclusions: Tumor budding is associated with poor prognostic factors. As it may be important to guide
the treatment modality and follow-up, tumor budding status may be mentioned in routine pathology reports.

Aim: Gallbladder cancer is an uncommon, but aggressive tumor. Its prognosis is poor and the most cases are incidentally detected in histopathological examinations of cholecystectomies due to benign diseases. With the era of laparoscopic cholecystectomy, the number of cases detected in early stage is increasing. In this study, we aimed to evaluate the rate of cancer encountered and the distribution of non-cancer diagnoses in cholecystectomy materials sent to our department, together with the literature findings.

Materials and Methods: The results of the cholecystectomy materials sent to the pathology laboratory and examined routinely in 2016-2017 were retrospectively evaluated by forming diagnostic groups. Clinical preliminary diagnoses, demographic informations (age, sex), and pathology reports of the patients were reviewed.

Results: We included a total of 1000 cholecystectomy materials into the study. Two of the 7 patients who presented with malignancy were incidentally diagnosed and underwent laparoscopic cholecystectomy with the preliminary diagnosis of cholelithiasis, with the primary focus was gallbladder in one patient, and the other was compatible with colonic adenocarcinoma infiltration. Preoperative and / or perioperative malignancy was detected in the remaining 5 patients. A large proportion (> 90%) of the other cases had chronic or chronic active cholecystitis and low rate of acute cholecystitis included gastric heterotopia found in 2 (0.2%), tubular adenoma in 1 (0.1%), tubulovillous adenoma in 1 (0.1%), adenomyoma / adenomyomatosis in 4 (0.4%), polyp in 6 (0,6%) and dysplasia (Biliary intraepithelial neoplasia, BilIN) in 5 (0.5%) patients.

Purpose: Laryngeal squamous cell carcinoma poses a management challenge due to the lack of reliable prognostic markers. Although tumor budding (TB) has been shown to predict poor prognosis in some malignancies, its prognostic significance in laryngeal cancer remains uncertain in the literature. Therefore, the objective of this study is to evaluate the impact of TB on prognosis and its correlation with other established prognostic factors in laryngeal squamous cell carcinoma.

Patients and Methods: In the department of otolaryngology the files of 60 patients with laryngeal squamous cell carcinoma who underwent surgery, postoperative chemoradiotherapy between 2008 and 2015 were analyzed retrospectively. The patient’s history, family history, age, TNM (tumor, node, metastases) classification, radiological imaging, type of surgery performed, and the results of the pathological specimen were evaluated. PanCK immunohistochemical staining was performed on old paraffin block sections containing tumoral tissue, previously stained with Hematoxylin & Eosin. The TB scores were evaluated by the pathology department, and the association between all obtained parameters and clinicopathological variables was analyzed.

Results: Our findings showed a significant association between tumor budding and perineural infiltration, a known prognostic factor for laryngeal carcinoma (P=0.006). TB was found to be an independent risk factor for perineural infiltration and pathological lymph node involvement (p=0.003). Pathological lymph node involvement was also found to be an independent risk factor for lymphovascular invasion (p=0.028).

Conclusions: Our study provides evidence for a significant association between tumor budding and perineural infiltration, which are established prognostic factors in laryngeal carcinoma. This suggests that tumor budding may be an important factor in determining tumor prognosis.

Objective: The aim was to review the hormonal status, treatment and histopathological diagnosis of patients admitted to our endocrinology outpatient clinic with the diagnosis of adrenal incidentaloma.

Material and Methods:Between 2015-2018, 217 patients with adrenal incidentaloma who were admitted to the endocrinology outpatient clinic were included in the study. 1 mg overnight dexamethasone suppression test (DST), 24 hour urine free cortisol, 24-hour urine methanephrine and normetanephrine levels were evaluated in all patients.Patients who also have hypertension or hypokalemiawere screened for the plasma aldosterone/renin activity ratio. CT or MRI imaging properties of adrenal incidentalomas were screened.

Results: In the evaluation of cases; 180 (83%) of the masses were evaluated as non-functional and 37 (17%) as functional. Of the 37 patients evaluated as having functional adrenal mass; 10 (4.6%) pheochromocytoma, 5 (2.3%) Cushing's syndrome, 9 (4.1%) subclinical Cushing’s syndrome and 13 (6%) primary hyperaldesteronism were detected. In 180 patients who were evaluated as having non-functional adrenal mass; metastatic disease in 7 (3 non-small cell lung cancer, 1 breast cancer, 1 prostate carcinoma and 2 unknown primary cancer), myelolipoma in 4, ganglioneuroma in 1, hydatid cyst in 1, adrenocortical carcinoma in 2 patients were detected.

Conclusion: According to the results of this study, it is not uncommon for adrenal incidentalomas to be functional. It may be malignant in some cases. For this reason, adrenal incidentaloma is a condition that should be examined both in terms of
functionality and malignancy potential.

Objective: Dermoscopic features of basal cell carcinoma (BCC) have been well described in the literature, however, blue white variant of BCC has recently been described as a mimicker of melanoma. When reviewing the literature, it seems that there is just one original research about this special type of BCC. Here we aimed to evaluate this special and challenging variant of BCC cases of two dermatology departments from different regions of Turkey. 

Material and methods: Dermoscopic images of the histopathologically approved BCC cases  from two centers between the years 2015-2018 were reviewed. The cases showing diffuse blue white areas on dermoscopy were included in the study. The clinical and histopathological features, dermoscopic images and demographic data of all the cases were evaluated

Results: We detected 15 (9.74 %) lesions of BCC with diffuse blue-white dermoscopic pattern from 15 different patients among 154 cases of histopathologically confirmed basal cell carcinomas. All of the cases were located on the head region. All of the cases were excised with two main differantials: melanoma and BCC. The most common findings after blue white diffuse areas were irregular serpentine vessels (60.0 %), peripheral maple leaf like areas (46.6%) and ulceration (46.6%). The histopathological examination of all the cases were in keeping with nodular or noduloulcerative subtypes.

Conclusion: The present study, to the best of our knowledge, is the most comprehensive study regarding this rare and challenging presentation of BCC. The main differential diagnosis is melanoma. We suggest that it would be logical to consider blue white BCC in the lesions showing diffuse blue-white color. A careful dermoscopic examination regarding the presence of specific dermoscopic clues to basal cell carcinoma can provide a well-directed preliminary diagnostic evaluation.

Aim: In this study, we aimed to present our 10-year experience regarding clinicopathology characteristics and
overall survival of 69 patients with adenocarcinomas of esophag ogastric junction (AEJs).
Patients and Methods: A total of 69 consecutive patients diagnosed with AEJ and operated in our clinics
were included in the study. Patients’ demographic characteristics; laboratory parameters, surgical resection
approach; TNM stages; resection extent; total number of removed lymph nodes; tumor localization; presence
of lymphatic, vascular and perineural invasion and overall survival (OS) status were recorded. The patients
were divided into two groups as Siewert Type II and Siewert Type III.
Results: There was no statistically significant difference between the groups in terms of age (p=0.696)
and gender (p=0.140). Distribution of T stage was statistically significantly different between the groups
(p=0.026). OS was found to be significantly higher in patients at R0 level compared to those at R1 level. OS
was statistically significantly higher in patients without lymphatic, vascular and perineural invasion. 1-year OS
was determined as 83.50%, 3-year OS as 49.10% and 5-year OS as 43.60%. The risk of mortality increased
by 8.63 folds in the presence of perigastric fat infiltration, 12.60 folds in the case of vascular invasion and
13.45 folds in the case of perineural invasion. The survival rate was found as 51% and 41% in the Siewert
Type II and Type 3 patients at median 10-year follow-up.
Conclusion: This study had successfully evaluated the clinicopathological characteristics and overall
survival, and demonstrated that Siewert II tumors and Siewert III tumors had similar survival outcomes.
Further comprehensive multicenter studies with larger series and long-term studies are needed to provide
contribution to the existing evidence on outcomes of patients w ith AEJs.

Objective: Most of the renal neoplasms are the epithelial and malign ones. The renal cell carcinoma (RCC), which is the most frequently seen malign renal tumor, consists of 2-4% of all the malign tumors seen among adult individuals and 80-90% of all the malign renal tumors. RCCs peak at sixties and seventies and its prevalence among males is two folds of its prevalence among females. RCCs have bad prognosis. The recurrence is seen in 40% of the cases, and the metastasis despite the early diagnosis was detected in 50% of cases. In present study, it was aimed to distribution of renal tumors in our hospital, discuss the prognostic factors such as the, pathological stage, nuclear grade and tumor diameter accompanied by literature information.

Patients and Method: By retrospectively scanning the records of Pathology Department of Medical Faculty, Fırat University, for the period between 1988 and 2009, 140 renal tumor cases were determined and the previous diagnoses, histological degrees, pathological stages of these cases were evaluated and the final diagnoses were taken as base in the present study. In pathologically staging (pT) of RCCs, TNM classification was used, whereas Fuhrman nuclear grading (FNG) was used in nuclear grading procedure. The patients were divided into different groups based on their genders and ages. The statistical analyses were performed in SPSS-12.0 software by using Chi-Square and Correlation tests.

Results: When compared to the literature in terms of the mean age, the present study involves relatively young population (mean age 57), and the majority was male (male/ female:1.1). The distributions of renal tumours, malign and benign subtypes, and RCC subtypes show similarities with the general literature. When examining the RCCs statistically, no significant relationship was found between diagnosis and age, and between nuclear grade and tumor diameter (p>0.05). In the present study, the RCCs with largest diameter were papillary type (9,78cm) ones, whereas the RCCs with lowest diameter values were classic type. A statistically significant relationship was observed between the benign, borderline and malign tumor diagnoses and diameters (p= 0.023). It was determined that approximately one-four of RCC cases were in highly pathological stage (21,6%, pT3a-3b). A direct proportional and statistically significant relationship was found between nuclear grade and diameter (p=0,002).

Conclusion: RCCs have poor prognosis and their frequency is increasing. Pathological stage, nuclear grade and diameter are the leading factors affecting the prognosis. As in our study, in retrospective studies involving old ages and not enough sampling, tumor diameter may be used as an alternative prognostic factor for pathological staging in tumors with a stage above pT2.

\r\n Objective: Early diagnosis of cutaneous squamous cell carcinomas (CSCC) is the most important factor affecting prognosis and most patients have a good prognosis. Some patients defined as high-risk group have high rates of regional recurrence and distant metastasis, and follow an aggressive course. In addition, recently numerous studies have being performed for determining the importance of sentinel lymph node sampling, and sentinel lymph node (SLN) positivity has been associated with a poor prognosis. In this study, we aimed to determine prognostic importance of SLN outcomes in patients with high-risk patients diagnosed with CSCC.

\r\n Patients & Methods: A total of 29 patients who underwent excisional operation in various body regions with the diagnosis of CSCC between 2009 and 2017, with available complete clinical and pathologic data were included in the study. At least 9-month clinical follow-up results, high risk factors and sentinel lymph node biopsy outcomes of the patients were recorded and analyzed. Patients with at least one of the American Joint Committee on Cancer (AJCC) criteria were considered as high-risk group.

\r\n Results: Twenty-five of the 29 CSCC patients were in the high-risk group. SLN positivity rate was 12% (n: 3/25) in the high-risk CSCC patients, all patients in the low-risk group had negative SLNs. All patients with SLN positive underwent local complementary lymphadenectomy, and all of these patients were re-operated due to recurrence. The rate of recurrence was found as 100% (n= 3/3) in high-risk CSCC patients with positive SLN, and 18% (n= 4/22) in high-risk CSCC patients with negative SLN. High recurrence rates (41.6%) and SLN positivity were observed in patients with hand-foot localizations.

\r\n Conclusion: High rates of local recurrence may be seen during progression of the disease in SLN positive patients. Hand-foot localization of CSCCs can be considered as a high risk factor regardless of a tumor diameter should be above 0.6 cm.

Objective: Conjunctiva is a region where various neoplastic or non-neoplastic lesions may develop.  In this study, we aimed to perform a histopathological analysis of conjunctival lesions and to determine their prevalence.

Material & Methods: Conjunctival biopsies of 401 patients who presented to the pathology laboratory between 2009 and 2019 were retrospectively examined. The cases were histopathologically divided into two groups as non-neoplastic and neoplastic lesions. Neoplastic lesions were further divided into subgroups as benign, premalignant, and malignant lesions. The prevalence of lesions and distribution of age and gender among the groups were analyzed.

Results: In our series of 401 patients, the mean age was 49.89±21.75 years. Of all patients, 209 (52.1%) were male and 192 (47.9%) were female. Non-neoplastic lesions were found in 296 (73.8%) and neoplastic lesions in 105 (26.2%) patients. The mean age was found as 50.79±19.34 years in patients with non-neoplastic lesions, and 47.34±27.39 years in patients with neoplastic lesions. Of neoplastic lesions, 64 (60.2%) were benign, 17 (16.2%) premalignant, and 24 (22.6%) malignant. The most commonly found non-neoplastic lesion was pterygium (n:220; 54.78%) while the most common benign lesions were nevus and other pigmented lesions (n:38; 9.5%), and the most common malignant lesion was squamous cell carcinoma (n:14; 3.5%). The prevalence of neoplastic lesions significantly increased over 45 years old (p<0.05).

Conclusion: In the current study, conjunctival lesions diagnosed in our laboratory over 10 years were reviewed and histopathologically analyzed. Recognition of conjunctival lesions and being aware of the rates of non-neoplastic and neoplastic lesions are crucial for treatment planning and protection of visual functions.

ABSTRACT

Objective: Endometrial cancer is the most common malignancy of the female genital tract and the fourth leading cancer among women. Our aim is to share the surgical treatment and results of endometrial cancer cases in our gynecological oncology clinic.

Material and Methods: In this study, the records of 164 endometrial cancer patients operated by the same surgical team between 2009-2019 were reviewed retrospectively. The clinical, surgical and histopathological features of the patients are presented here. Four patients who had sarcoma as a result of pathology, 7 patients who underwent complementary surgery and 1 patient with a second primary tumor were not included in the study.

Results: The mean age of the patients included in our study was 61.3 and the mean body mass index was 25.8. According to the postoperative pathology results; mean tumor size was 3.4 cm and mean number of collected lymph nodes was 28.8. Lymph node metastasis was observed in 19 patients and all of the metastases were in pelvic lymph nodes. Endometrioid type adenocarcinoma was seen in 81% of the patients. Myometrial invasion > 50% in 81 patients (49.4%). Twenty patients (12.2%) had cervical involvement, 11 patients (6.7%) had adnexal involvement and 28 patients (17.1%) had lymphovascular area invasion. 76 patients (46.3%) were grade 1, 61 patients (37.2%) were grade 2, 19 patients (11.6%) were grade 3. When the patients were staging according to the FIGO system in 2009, 70 (42.7%) stage 1A, 58 (35.4%) stage 1B, 12 (7.3%) stage 2, 3 (1.8%) stage 3A 17 patients (10.4%) were stage 3C1 and 4 patients (2.4%) were stage 4.

Conclusion: Endometrial cancer is the most common gynecological cancer, and it is usually diagnosed at an early stage as a result of early signs. Tumor size, depth of myometrial invasion and histopathologic grade are used to evaluate the risk of the disease, but studies with a higher number of high stage patients will be more useful in determining the risk.

Objective: Pap smear test is a commonly used and effective screening method in detection of cervical cancer and its precursor lesions. There is a very limited number of studies on use of Pap smears in diagnosis of the endometrial carcinomas. We have aimed to investigate the incidence rate of atypical endometrial cells in Pap smears of the patients diagnosed with endometrial carcinoma and the correlation between these cells and clinicopathological parameters.

Material and methods: In this study, patients who were diagnosed with endometrial carcinoma and who had smear sampling between January 2015 and September 2017 were examined retrospectively. Histological type, nuclear grade and Pap smear results of endometrial carcinoma cases were evaluated.

Results: Pap smear sampling was concurrently performed in 59 of the 97 patients diagnosed with endometrial carcinoma. The ages of the patients who underwent smear sampling ranged between 42 and 82 years (mean 57.43±9.08 years). The menopausal status evaluation of the women revealed that 12 (20.3%) and 47 (79.7%) patients were premenopausal and postmenopausal, respectively. Endometrioid type carcinoma was encountered in 51 (86.4%) patients as the most commonly found histological type. Serous, clear cell and mucinous carcinomas were determined in 6 (10%), 1 (1.8%) and 1 (1.8%) patients, respectively. The results of Pap smear tests were atypical in 24 (40.7%) patients whereas normal results were obtained in 35 (59.3%) patients. Nuclear grade assessment of the carcinomas showed that grade 1, grade 2 and grade 3 carcinomas were discovered in 24 (40.7%), 25 (42.3%) and 10 (17%) patients, respectively. The rate of the atypical endometrial cells encountered by Pap smears has increased as grade of the tumors increased.

Conclusion: We have concluded that the detection rate of atypical cells by Pap smear in endometrial carcinomas is considerably high. The incidence of atypical cells is higher in nonendometrioid and high-grade carcinomas.

 Fourty one years old female and 64 years old man were admitted to our clinic  because of abdominal pain. In investigating the liver was reported with a giant hemangioma. It was symptomatic and look like malignancy for each cases so they were operated. In operation it was not a liver mass , one of them observed right giant adrenal adenoma and the second one is renal cell carsinoma.  Resection was performed for each cases. Adrenal mass could be noted that mixed hemangiomas.

Aim: In this study, it was aimed to investigate the kidney function, hypertension development and
proteinuria in individuals with only one kidney .
Patients and Methods: The study included 96 patients who had previously undergone nephrectomy with
the causes of nephrolithiasis and chronic pyelonephritis-induced nonfunctional kidney, RCC (Renal Cell
carcinoma), trauma, and donor nephrectomy among 17800 patients who applied to the Siirt State Hospital
Nephrology and Urology outpatient clinics between January 2016 and December 2019. The data of the
patients were obtained from patient files database retrospectiv ely.
Results: A total of 96 patients, 45 female and 51 male, were included in the study. 23 (24%) of the
patients had donor nephrectomy (DN), and 73 (76%) had nephrectomy (DE) due to nephrolithiasis, chronic
pyelonephritis, trauma, and renal cell cancer (RCC). The patients were divided into two groups as those
who underwent DN and DE due to other etiologies. Between DN and DE group, there was no statistically
significant difference in terms of mean age, distribution of gender, presence of HT before nephrectomy,
DM, presence of hematuria and new onset proteinuria (P> 0.05). Compared to the DN group, the frequency
of new onset in CKD and HT development was significantly higher DE group.
Conclusion: Nephrectomy is a risk factor for the development of CKD, proteinuria and hypertension.
Therefore, preventive measures should be taken in a timely manner to reduce the prevalence of
nephrectomies due to benign diseases.
