Diagnostic cytological features and differential diagnosis of subacute granulomatous (De Quervain's) thyroiditis.

Background: The aims of the study are to identify the diagnostic cytological features of subacute granulomatous thyroiditis (SGT), to compare our results with previous literature studies, and to investigate the cytological changes in SGT that mimic other thyroid lesions.

Methods: This retrospective study was conducted with 69 cases. The cytology slides were re-evaluated.

Should pancreas cyst fluids be divided into two for cytological diagnosis and biochemical tests?

Background/aims: The aim of the present study was to investigate whether pancreas cyst fluids should be divided into two for cytological diagnosis and biochemical tests.

Materials And Methods: The present study was conducted with fluids aspirated from 12 pancreas cysts. The fluids were divided into two and sent to the cytopathology (fluid 1) and biochemistry (fluid 2) laboratories.

Comparison of muscle-to-nodule and parenchyma-to-nodule strain ratios in the differentiation of benign and malignant thyroid nodules: which one should we use?

Objective: The aim of this study is to investigate the diagnostic accuracy of muscle-to-nodule strain ratio (MNSR) in the differentiation of benign and malignant thyroid nodules and to see if there was a difference between MNSR and parenchyma-to-nodule strain ratios (PNSR) in diagnosis.

Methods: A total of 106 consecutive patients (88 women and 18 men; age range 19-79 years) with thyroid nodules were prospectively examined using ultrasound and sonoelastography before the fine-needle aspiration biopsy. The mean MNSR and PNSR were calculated for each nodule and the elasticity score was determined according to four-point scoring system.

Clinical, histopathological and mineralogical analysis findings of an unusual case of pneumoconiosis.

A 43-year-old man with a long history of dyspnea which had progressively worsened over the preceding month is presented. He had worked in an antimony mine for 3 years. Radiologically, there were diffuse reticulonodular shadowing opacities in both lung parenchymas.

Fine-needle aspiration cytology of metastatic oligodendroglioma: case report and literature review.

Background: Systemic metastasis of a glial tumor is a rare event. However, metastatic cases are anticipated to increase due to prolongation of survival as a result of the development of new treatment modalities. The possibility of metastasis should be considered in patients with a history of a glial tumor rather than a second primary tumor.
