Chronic thyroiditis may present a focal lesion, often-palpable abnormality, simulating nodular disease. The number and morphology of the Hürthle cells (HC) vary in the thyroid aspirate. Distinguishing between neoplastic and non-neoplastic HC lesions is difficult when using the fine-needle aspiration cytology (FNAC). We present the case of a 46-year-old female with a large right nodular goiter and hypothyroidism and high titer of anti-thyroid peroxidase antibody (TPO). The thyroid ultrasound showed a large well-defined nodule (more than 6...

A 51-year-oldwoman with a right renal mass was referredto our hospital. Computedtomographic (CT) scan demonstrated a 30 mm-diameter renal mass with delayed enhancement. She underwent a robotassistedlaparoscopic right partial nephrectomy. The pathological examination showedthat tumor cells with eosinophilic, clear cytoplasm formedtubules of various sizes containing colloid-like material, which resembled the findings of thyroidfollicular carcinoma. The tumor was immunoreactive for vimentin andcytokeratin (CK) 7, whereas it lackedreactivity for thyroidtranscription factor-1 (TTF-1) or thyroglobulin...

Nanoparticles (NPs) of noble metals, namely gold and silver, remain promising anticancer agents capable of enhancing current surgery- and chemotherapeutic-based approaches in cancer treatment. Bimetallic AgAu composition can be used as a more effective agent due to the synergetic effect. Among the physicochemical parameters affecting gold and silver nanoparticle biological activity, a primary concern relates to their size, shape, composition, charge, etc. However, the impact of metal components/composition as well as metal topological distribution within NPs is incompletely characterized and remains to be further elucidated and clarified...

Novel therapeutic approaches are required for the less differentiated thyroid cancers which are non-responsive to the current treatment. In this study we tested an innovative formulation of nanoliposomes containing sildenafil citrate or tadalafil, phosphodiesterase-5 inhibitors, on two human thyroid cancer cell lines (TPC-1 and BCPAP). Nanoliposomes were prepared by the thin layer evaporation and extrusion methods, solubilizing the hydrophilic compound sildenafil citrate in the aqueous phase during the hydration step and dissolving the lipophilic tadalafil in the organic phase...

Renal oncocytoma and chromophobe renal cell carcinoma (RCC) have been long recognized as distinct tumors; however, it remains unknown if uniform diagnostic criteria are used to distinguish these tumor types in practice. A survey was distributed to urologic pathologists regarding oncocytic tumors. Responses were received from 17/26 invitees. Histologically, >1 mitotic figure was regarded as most worrisome (n=10) or incompatible (n=6) with oncocytoma diagnosis. Interpretation of focal nuclear wrinkling, focal perinuclear clearing, and multinucleation depended on extent and did not necessarily exclude oncocytoma if minor...

BACKGROUND: Solid variant of papillary thyroid carcinoma is a rare subtype of papillary thyroid carcinoma (PTC) containing a solid component (SC), and thus its cytological and clinicopathological features remain elusive. We examined fine needle aspiration (FNA) cytological features of PTC with variable degrees of SC (20-80% of the tumor)(PTCSC) in comparison to well-differentiated PTC (WPTC). METHODS: Twenty-six cases of PTCSC were histologically stratified into major-SC (SC >50% of the tumor) and minor-SC (<49%) groups...

Cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC), which has a better prognosis, is seen mostly in the setting of familial adenomatous polyposis (FAP). The cytomorphology of CMV-PTC is diverse; hence, it could be mistaken for other thyroid neoplasms with bad prognostic outcome. This case is of a 24-year-old female diagnosed with polyposis coli found to have thyroid nodules at screening ultrasonography. Aspirated thyroid smears were hypercellular with epithelial cells arranged in monolayer sheets, papillae with discohesion, and spindling of cells at the edges, cribriform clusters, and cell morules...

AIM: It is a diagnostic challenge to differentiate benign and malignant cytology in the presence of Hürthle cells. In our previous study, it was determined that in fine needle aspirations (FNA), the malignancy outcome of the Hürthle cells containing group tend to be papillary thyroid carcinoma (PTC) in a higher percentage. The most common misinterpretation is caused by PTC cells with large cytoplasm-like Hürthle cells. The aim of this study is to predict histologic outcome of the nodules, which have Hürthle cells in FNA according to cytological, clinical features, and BRAF(V600E) mutation status...

A 51-year-old woman with recurrent paragangliomas and catecholamine hypersecretion underwent F-FDG PET/CT for localization and evaluation of extent of disease. This revealed multiple F-FDG avid tumors with localization pattern suggesting multiple primary neoplasms of different origin rather than disseminated paraganglioma. Three additional nuclear medicine investigations were performed (F-DOPA PET/CT, Ga-DOTATOC PET/CT and I-MIBG scintigraphy) to further characterize tumor biology, guide diagnostic workup, and decide treatment strategy...

Serous cystic neoplasms (SCNs) are benign cystic neoplasms that predominantly occur in the tail of the pancreas in elderly women. It is well known that patients with von Hippel-Lindau syndrome can develop SCNs and neuroendocrine tumors in the pancreas. However, our understanding on SCNs accompanying other pancreatic tumors (SCNAOPTs) is limited. We compared the clinicopathologic features of 15 surgically resected SCNAOPTs with 259 conventional SCNs. The prevalence of SCNAOPT was 5%. The SCNAOPTs were significantly smaller than conventional solitary SCNs, and they were more commonly observed in the head of the pancreas, while conventional solitary SCNs were more frequently noted in the body and tail...
