These include inflammatory, metaplastic, and cystic lesions. We aimed to draw attention to rare tumor-like lesions that can be confused with malignancies and cause diagnostic difficulties clinically and radiologically. Methods: A total of 538 patients who underwent nasopharyngeal biopsy in our center between January 2010 and June 2020 were evaluated. Patient information was obtained from patient files and evaluated retrospectively. Results: A total of 19 of the 538 patients had tumor-like lesions that were included in the study. Granulomatous inflammation was present in seven cases, oncocytic metaplasia in four cases, benign cyst in five cases, fungal infection in two cases, and immunoglobulin G4-related disease in one case. Conclusions: The nasopharynx is a region where various lesions can be seen. Some lesions form tumor-mimicking mass effect, cause increased thickness, and lead to increased metabolic activity in positron emission tomography-computed tomography that create the illusion of a malignant tumor and histopathologic verification is crucial. We aimed to present these rare tumor-like lesions that should be kept in mind in the differential diagnosis.Publication Cancer tendency in a patient with ZNF341 deficiency(Springer/Plenum Publishers, 2020-01-20) Çekiç, Şükrü; Hartberger, Julia Maria; Frey-Jakobs, Stefanie; Hüriyet, Hüzeyfe; Hortoğlu, Melika Bektaş; Neubauer, Johanna Charlotte; Karalı, Yasin; Abakay, Candan Demiröz; Saraydaroğlu, Özlem; Çavaş, Tolga; Grimbacher, Bodo; Kılıç, Sara Şebnem; ÇEKİÇ, ŞÜKRÜ; Huriyet, Huzeyfe; BEKTAŞ HORTOĞLU, MELİKA; KARALI, YASİN; DEMİRÖZ ABAKAY, CANDAN; SARAYDAROĞLU, ÖZLEM; ÇAVAŞ, TOLGA; KILIÇ GÜLTEKİN, SARA ŞEBNEM; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatrik İmmünoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyasyon Onkolojisi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; 0000-0002-9574-1842; 0000-0003-1620-1918; 0000-0002-6897-6806; 0000-0001-8571-2581; 0000-0002-5617-8313; L-1933-2017; JBJ-7521-2023; AAH-3855-2021; AAA-4154-2022; AAH-1658-2021; AAH-9701-2021; AAH-3508-2021; CVI-9578-2022; FFS-1974-2022Publication A case of adrenal mass causing adrenal insufficiency: Tuberculosis(Aves, 2017-03-01) Şişman, Pınar; Peynirci, Hande; Saraydaroğlu, Özlem; Sahin, Ahmet Bilgehan; Gül, Özen Öz; Ersoy, Canan; Şişman, Pınar; Peynirci, Hande; SARAYDAROĞLU, ÖZLEM; ŞAHİN, AHMET BİLGEHAN; ÖZ GÜL, ÖZEN; ERSOY, CANAN; Uludağ Üniversitesi/Tıp Fakültesi/Endokrinoloji ve Metabolizma Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/İç Hastalıkları Anabilim Dalı.; 0000-0002-7846-0870; AAM-4927-2020; AAH-9701-2021; AAI-1005-2021; AAH-8861-2021; GRY-0605-2022; DUS-9872-2022Tuberculosis, the prevalence of which has continued to decline in developed countries, is still one of the reasons of adrenal insufficiency. In this report, we aimed to present a case of adrenal and miliary tuberculosis presenting with adrenal insufficiency. A 71-year-old woman with a history of unilateral adrenalectomy was admitted with the symptoms of adrenal insufficiency. In her further medical investigations, the diagnosis of primary adrenal insufficiency was established and a mass presenting as involvement of tuberculosis was detected in the adrenal gland. Bilateral pulmonary nodules compatible with miliary tuberculosis were observed. After anti-tuberculosis treatment, pulmonary nodules disappeared, but there was no significant decrease in the size of the adrenal mass. The patient, who underwent adrenalectomy, was followed with glucocorticoid and mineralocorticoid treatment. Tuberculosis of the adrenal glands is a common cause of adrenal insufficiency in developing countries. Tuberculosis can destroy the adrenal glands and the diagnosis of adrenal tuberculosis, especially presenting with enlargement of the adrenal glands, can be difficult.Publication Differences between atypical parathyroid tumors and parathyroid adenomas in patients with primary hyperparathyroidism(Springer India, 2023-09-29) Aydemir, Ensar; AYDOĞAN ÜNSAL, YASEMİN; ÖZ GÜL, ÖZEN; AYDEMİR, ENSAR; ATEŞ, COŞKUN; Ateş, Coşkun; CANDER, SONER; Cander, Soner; Saraydaroğlu, Özlem; SARAYDAROĞLU, ÖZLEM; Ersoy, Canan; ERSOY, CANAN; Ertürk, Erdinc; ERTÜRK, ERDİNÇ; Bursa Uludağ Üniversitesi/Tıp Fakültesi/İç Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/İç Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; 0000-0003-4300-2965; 0000-0003-4565-9848; 0000-0002-1332-4165; AAJ-6536-2021; AAB-6671-2022; AAA-7171-2022Atypical parathyroid tumor is a rare disease that can be challenging to distinguish from parathyroid adenoma. Atypical parathyroid tumor shows some laboratory and histopathological features with parathyroid cancer. This study attempts to compare clinical, laboratory, radiologic, and histopathological characteristics in atypical parathyroid tumor and parathyroid adenoma. This was a retrospective study based on the database of eighty-two subjects who underwent surgery for primary hyperparathyroidism at a tertiary referral center between 2010 and 2021. Forty-one patients with atypical parathyroid tumor were matched by age and gender to controls with parathyroid adenoma. Clinical, laboratory, radiologic, and characteristics were obtained from the hospital database. Forty-five (54.8%) of primary hyperparathyroidism patients were symptomatic, 36 (90%) had nephrolithiasis, 6 (15%) had fracture, and 3 (7.5%) had hypercalcemic crisis. Atypical parathyroid tumor patients present with significantly increased serum calcium, parathormone, and alkaline phosphatase levels (P < .001, all). No significant difference was observed in the results of bone mineral density, T-scores, and Z-scores. The size of adenoma was significantly greater in the atypical parathyroid tumor group (24 (8.8-70) mm vs. 12 (3.8-32) mm, P = 0.005). Our study revealed that increased preoperative serum calcium, parathormone, alkaline phosphatase concentrations, and parathyroid adenoma size on ultrasound may have predicted the atypical parathyroid tumor.Publication C-kit (CD117) expression in patients with small cell lung cancer(Galenos Yayıncılık, 2015-03-01) Gözkaman, Ayşe; Okuturlar, Yıldız; Kanat, Özkan; Günald, Meral; Serin, Sibel Ocak; Saraydaroğlu, Özlem; Kumbasar, A.

The aim of this study was to search the role of CD117 (c-kit) overexpression as a prognostic marker in SCLC.Methods: Demographic and clinical data of patients with SCLC was registered. C-kit overexpression was evaluated using immunohistochemistry performed in paraffin-embedded specimens. Immunostaining data of 87 patients were correlated with survival and other relevant clinical parameters.Results: The mean age of the patients was 57.1 +/- 9.9 years. Thirty-nine patients (44.8%) had limited disease and 48 patients (55.2%) had extensive disease. C-kit (+) expression was observed in 24.1% of 87 patients. The mean survival time for c-kit (+) patients was 10.2 (CI=5.7-14.7) months as compared with the c-kit (-) population in whom the survival was 14.7 (CI=10.7-18.6) months. The difference in survival time between c-kit (+) and (-) patients was not statistically significant (p=0.264).Conclusion: New prognostic markers and more effective treatment regimens are needed for SCLC. Our findings may provide an insight to future clinical trials searching c-kit inhibitors in SCLC.
