Occult papillary thyroid carcinoma presented as isolated cervical lymphadenopathy without clinical and radiologic findings has been rarely reported. Case report. A 47 years old female patient admitted to otorhinolaryngology clinic with 4X3 cm sized cervical mass. Physical examination of the patient was noted as a nontender, firm, mobile lymph node at right lateral cervical region. There was no inflammatory or infection disease in the history of patients anamnesis and no abnormal value on laboratory tests. Ultrasound screening of the neck detected a lymph node with suspicious features for malignancy. Head and neck examination was normal and there is no evidence of a tumoral mass or nodule in the thyroid gland. Whole body scan of MRI showed no pathologic sign both in the neck and body. Excisional biopsy was performed and revealed a carcinoma with papillary morphology. Immunohistochemical staining features of the tumor confirmed a papillary carcinoma derived from the thyroid gland. Second look USG of the neck and thyroid was performed but it revealed no tumoral mass. The patient underwent total thyroidectomy with right functional and central lymph node dissection. Histological examination of the thyroid gland showed multicentric 2 mm sized, three foci of papillary carcinoma located in bilateral thyroid lobes and metastatic lymph nodes in the right side of the neck. Conclusion. A metastatic cervical lymph node can be evidence of a clinically undetected occult papillary thyroid carcinoma. Specific immunohistochemistry staining of specimen may lead to appropriate surgery and progression of carcinoma may be hindered by application of additional RAI therapy.Öğe Correlation between pre-radical prostatectomy Standardized SUVmax ratios detected on 68Ga-PSMA-I&T PET/CT and final histopathology outcomes: An in-depth analysis(Elsevier Espana Slu, 2024) Arikan, M. G.; Soyluoglu, S.; Korkmaz, U.; Tastekin, E.; Elboga, U.; Arda, E.Objective: To evaluate the predictive potential of the maximum standardized uptake value (SUVmax) value of intraprostatic tumors derived from preoperative [Ga- 68 ]Ga-PSMA-I&T PET/CT (SUVT), and its ratios to SUVmax in the liver (SUVTLR) and parotid gland (SUVTPR) with respect to histopathological findings. Materials and methods: Data from patients who underwent radical prostatectomy (RP) for prostate cancer (PC) at our clinic between 2017-2020 were assessed. Patients with a secondary malignancy, a history of transurethral prostate resection, prior treatment for PC, or who received salvage RP were excluded. Whole -body images obtained using the same device, as per the guidelines, were reviewed by two nuclear medicine specialists with more than a decade of experience to reach a consensus for each lesion. The relationships between age, PSA, Prostate Volume, clinical T stage, biopsy International Society of Urological Pathology grade (ISUP), D'amico risk group, intraprostatic tumor volume (HPTV) identified in the final histopathological specimen review, HP-ISUP grade, seminal vesicle invasion (SVI), extracapsular invasion (ECI), positive surgical margine (PSM), SUVT, SUVTLR, and SUVTPR were analyzed. Results: The mean age of the 64 included patients was 64.1 +/- 5.3 y -o. A statistically significant correlation was found between SUVT, SUVTLR, SUVTPR values, and histopathologic stage parameters, such as biopsy ISUP, D'amico Risk Classification, HP-ISUP, HPTV ( P <.05). PSMATV, SUVT, and SUVTLR were statistically significant predictors of extracapsular invasion, while PSA, PSMATV, and SUVTLR were significant predictors of SVI ( P <.05). Conclusion: The standardized SUVT, SUVTLR, and SUVTPR values could be employed as noninvasive markers to assist in predicting postoperative histopathological findings, particularly ECI, SVI, and PSM.Öğe Determination of the protective role of spexin and adropin in chronic renal failure induced cardiovascular damage(Wiley, 2019) Memi, G.; Yazgan, B.; Tastekin, E.[Abstract Not Available]Öğe Do Histological Patterns of Primary Tumor Predict Metabolic Patterns detected by FDG PET/CT in Differentiated Thyroid Cancer Patients(Springer, 2020) Soyluoglu, S.; Tastekin, E.; Korkmaz, U.; Orum, S.; Altun, G.
