Adamantinoma-like Ewing sarcoma (AES) is a rare variant of Ewing sarcoma family of tumors (EFTs), primarily affecting bone and soft tissue. AES has mixed features of Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) and adamantinoma with a complex immunoprofile and EWSR1 gene rearrangements. Herein, we report a 72-year-old male who presented with left parotid mass, right neck mass and thyroid nodules. Fine needle aspiration of the left parotid mass displayed nests of monotonous epithelioid cells with basaloid features in a background of small round blue cells and lymphocytes...

Tools to diagnose fungal infection are microscopic examination, antigen or antibody-based detection tests, molecular diagnostics, and culture, with culture being the "gold standard" for species-level identification. Although these methods are commonly used in concert and yield concordant results, in some cases tissue is not available for culture, and/or different methodologies yield discrepant results. These discrepancies may be clinically significant, causing confusion and inappropriate or delayed initiation of antifungals...

In Japan, fine needle aspiration (FNA) cytology is the most important diagnostic modalities for triaging patients with thyroid nodules. A clinician (endocrinologist, endocrine surgeon, or head and neck surgeon) generally performs FNA cytology at the outpatient clinic, and ultrasound (US)-guided FNA is widespread because US is extremely common and most clinicians are familiar with it. Although almost all FNA thyroid samples are examined by certified cytopathologists and pathologists, some clinicians assess cytological specimens themselves...

We reviewed the current status of thyroid fine needle aspiration cytology (FNAC) in Korea. Thyroid aspiration biopsy was first introduced in Korea in 1977. Currently, radiologists aspirate the thyroid nodule under the guidance of ultrasonography, and cytologic interpretation is only legally approved when a cytopathologist makes the diagnosis. In 2008, eight thyroid-related societies came together to form the Korean Thyroid Association. The Korean Society for Cytopathology and the endocrine pathology study group of the Korean Society for Pathologist have been updating the cytologic diagnostic guidelines...

BACKGROUND: The important diagnostic challenge facing the cytopathologist is whether a mesothelial proliferation on effusions represents a malignant mesothelioma (MM) or a benign mesothelial hyperplasia (MH). Here, we evaluated the diagnostic utility of BAP1 immunohistochemistry (IHC) in distinguishing between reactive and neoplastic mesothelial cells. METHODS: In pleural and peritoneal effusions from 147 patients with diagnosed MM or with a differential diagnosis of MM and MH, the expression of BAP1 was examined by IHC on paraffin-embedded cell blocks (n = 121) and biopsies (n = 44)...

BACKGROUND: Reported results for thyroid nodule fine needle aspiration (FNA) cytology mainly originate from tertiary centers. However, thyroid nodule FNA cytology is mainly performed in primary care settings for which the distribution of FNA Bethesda categories and their respective malignancy rates are largely unknown. Therefore, this study investigated FNA cytology malignancy rates of a large primary care setting to determine to what extent current evidence based strategies for the malignancy risk stratification of thyroid nodules are applied and applicable in such primary care settings...

BACKGROUND: Neuroblastomas (NBs) are the most common solid cancer of childhood and infancy; however, in poorly differentiated forms, they present diagnostic challenges. GATA3 has been implicated functionally in NB differentiation, and limited data support its use as an immunohistochemical biomarker for NBs in resection specimens. METHODS: GATA3 was tested retrospectively in 30 consecutive archival NB samples, including archival cytopathology needle cores and cell blocks (n = 6), scant surgical biopsy specimens and 2-mm NB tissue cores (n = 16), and air-dried touch imprints (n = 8) to evaluate the utility of this marker...

BACKGROUND: Fine needle aspiration (FNA) is widely used in the diagnosis of salivary gland lesions. Salivary gland FNAs are often difficult to diagnose because of morphologic heterogeneity, a small but significant number of the FNAs yield "atypical" diagnosis. However, systematic evaluation of the risk of malignancy (ROM) of the atypical diagnoses across institutions and the variability of ROM among institutions are still lacking. METHODS: Salivary gland FNAs from five tertiary medical centers of United States, Europe and China were reviewed...

Cytology is an easily accessible, cost-effective and safe procedure for the initial evaluation of most endocrine/neuroendocrine lesions. Both fine-needle aspiration cytology and exfoliative cytology have shown good sensitivity and specificity in detecting endocrine/neuroendocrine benign proliferations and malignancies. Thanks to its utility for early diagnosis, cytology has contributed to the decline in mortality of endocrine/neuroendocrine neoplasms. The endocrine system comprises different endocrine organs, such as the thyroid, adrenal glands, paraganglia, parathyroid, pancreas, hypothalamus, pituitary gland, ovaries and testes, which can give rise to non-neoplastic, benign and malignant proliferations...

BACKGROUND & AIMS: Despite the widespread use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) to sample pancreatic lesions and the standardization of pancreaticobiliary cytopathologic nomenclature, there are few data on inter-observer agreement among cytopathologists evaluating pancreatic cytologic specimens obtained by EUS-FNA. We developed a scoring system to assess agreement among cytopathologists in overall diagnosis and quantitative and qualitative parameters, and evaluated factors associated with agreement...

OBJECTIVE: Listening to music and other auditory material during microscopy work is common practice among cytologists. While many cytologists would claim several benefits of such activity, research in other fields suggests that it might adversely affect diagnostic performance. Using a cross-modal distraction paradigm, the aim of the present study was to investigate the effect of auditory stimulation on the visual interpretation of cell images. METHODS: Following initial training, 34 participants undertook cell interpretation tests under four auditory conditions (liked music, disliked music, speech and silence) in a counterbalanced repeated-measures study...

A uniform classification system for reporting urinary cytology has not been available until recently, although urinary cytology represents an important volume of specimens in cytopathology laboratories and is well-established in the diagnosis and follow-up of patients with urothelial carcinoma. The Paris system is the first internationally accepted classification system, which allows uniform reporting of urinary cytology based on standardized morphological criteria. It emphasizes the detection of potentially life-threatening high-grade urothelial carcinomas and well-defined diagnostic categories have been developed...
