BACKGROUND: Fine-needle aspiration (FNA) is routinely performed to evaluate salivary gland lesions, and provides valuable information regarding the cytomorphologic features of the lesions. Occasionally, there are overlaps between benign and malignant conditions due to heterogeneity of the cell types, metaplastic changes, and sampling issues. Herein, the authors present a retrospective study of diagnostic pitfalls in salivary gland cytology and the simulating conditions. METHODS: A 20-year retrospective review (1995-2015) of medical records was performed searching for the cytology reports of patients who underwent FNA of the salivary gland with the words "amendment" or "revision...

Cytomorphological and cytochemical staining are important methods for the identification of cell types, in particular in fish which often lack biological tools such as specific antibodies. Myeloperoxidase (MPO) is usually used as an intracellular marker of neutrophil accumulation in tissues and a marker of neutrophil activity in plasma. In this study, we reported a potassium iodide and oxidized pyronine Y (KI-PyY) staining method for rapid and highly sensitive detection of MPO-positive cells in turbot blood, peritoneum, and tissues...

Introduction: Tuberculosis caused by Mycobacterium tuberculosis is a chronic infectious disease and a major health problem in developing countries, with lymphadenopathy being the most common presentation. Tuberculous lymphadenitis can be diagnosed on fine needle aspiration cytology of lymph node. Conventional Ziehl-Neelsen method for acid fast bacilli plays a key role in the diagnosis and monitoring of treatment for tuberculosis, however, with low sensitivity. Present study emphasizes the role of bleach concentration method in fine needle aspiration cytology of lymph nodes over conventional direct smear microscopy...

Introduction: Cytologic features of papillary thyroid carcinoma (PTC) have been extensively documented in literature. However, PTC variants can prove to be diagnostically challenging on fine needle aspiration cytology (FNAC). Aims: To study the FNAC features of PTC and its variants and explore the causes for misdiagnosis. Materials and Methods: This is a retrospective study. All cases of histopathologically (HP) confirmed cases of PTC during a 2-year period (January 2012 to December 2013) with presurgical FNAC were included...

BACKGROUND: Although metastatic disease is commonly seen in high grade carcinomas of gynecologic origin, it also occurs in low to intermediate grade endometrioid carcinomas (LGEMCAs), and may even be the primary presentation of disease. Tissue confirmation is necessary to guide therapy, but performing biopsies might not always be feasible or practical. In such instances, fine needle aspiration (FNA) is a safe and efficient alternative. No comprehensive series describing the cytomorphologic features of metastatic LGEMCA on FNA samples has been published...

BACKGROUND: In general, the presence of circulating tumor cells (CTCs) in peripheral blood (PB) is associated with a relative shorter overall survival in cancer patients. The clinical utility of CTC diagnostics is changing: from prognostic test to an assay predicting therapy response, enabling the right choice of therapy and monitoring the effect of administered therapy. We present two case reports of patients with suspicion of lung and pancreatic cancer, without obtainable preoperative biopsy for histological verification...

Poorly differentiated thyroid carcinoma (PDTC) is a follicular cell-derived tumour that was recognised as a distinct entity by the World Health Organisation in 2004. The natural history and pathological features of PDTC are reported to be intermediate between those of well-differentiated and undifferentiated (anaplastic) thyroid carcinomas. Preoperative identification of PDTC could facilitate better initial patient management in many cases, namely more extensive surgery, without any delay. However, according to some experts, a diagnosis of PDTC can only be rendered on histologic specimens based on criteria recommended in the Turin proposal...

Interpretative criteria for programmed death-ligand 1 (PD-L1) immunohistochemistry (IHC) have been largely based on data from formalin-fixed, paraffin-embedded tissues, despite the fact that cytologic specimens, especially cell blocks, are often the only or most readily available tissue for testing. Unlike biopsy specimens, however, cytology sample processing methods can vary markedly. The purpose of this study was to evaluate the effects of several common preanalytic variables on PD-L1 IHC. Two cell lines with strong expression of PD-L1 (H441) and no expression (MCF7) were cultured in vitro...

Cryptococcus neoformans is the most common microorganism found in cerebrospinal fluid (CSF) cytology and causes life-threatening infections in immunocompromised hosts. Although its cytomorphologic features in conventional smear cytology have been well described, those in liquid-based cytology have rarely been. A 73-year-old woman with diffuse large B-cell lymphoma presented with mental confusion and a spiking fever. To rule out infectious conditions, CSF examination was performed. A cytology slide that was prepared using the ThinPrep method showed numerous spherical yeast-form organisms with diameters of 4-11 μm and thick capsules...

BACKGROUND: Well-differentiated (WD) and poorly differentiated (PD) pancreatic neuroendocrine neoplasms are biologically distinct entities with different therapies and prognoses. WD neoplasms with elevated proliferation (Ki-67 > 20%) have been shown to have an overlapping histology with PD neuroendocrine carcinomas. This study compared expert cytomorphologic assessments of differentiation in pancreatic neuroendocrine neoplasms in a multi-institutional study. METHODS: Fine-needle aspiration specimens from pancreatic neuroendocrine neoplasms (grade 2 [G2] and grade 3 [G3] according to the 2017 World Health Organization classification; n = 72) were diagnosed independently by 3 cytopathologists as WD or PD (poorly differentiated large cell type [PD-L] or poorly differentiated small cell type [PD-S]) purely on the basis of cytomorphology...

Osteosarcoma is the most frequent malignant disease of the bone. On the basis of early clinical experience in the 1960s with H-1 protoparvovirus (H-1PV) in osteosarcoma patients, this effective oncolytic virus was selected for systematic preclinical testing on various osteosarcoma cell cultures. A panel of five human osteosarcoma cell lines (CAL 72, H-OS, MG-63, SaOS-2, U-2OS) was tested. Virus oncoselectivity was confirmed by infecting non-malignant human neonatal fibroblasts and osteoblasts used as culture models of non-transformed mesenchymal cells...

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare but serious complication in patients with breast implants, Patients are at risk of BIA-ALCL whether they receive breast implants for cosmetic reasons or for reconstructive purposes after surgery for breast cancer or prophylactic mastectomy. During the past decade, an increased number of reports have addressed BIA-ALCL. Herein, we describe BIA-ALCL in a transgender woman. The patient received breast implants as part of her gender transition and was diagnosed with BIA-ALCL 20 years later...

The MiT family translocation renal cell carcinomas (RCCs) are relatively rare in comparison to the conventional RCC. The cytologic features overlap with conventional clear cell RCC and papillary RCCs, thereby making the diagnosis extremely challenging. Here, we describe a case of TFE3 translocation associated RCC in a 58-year-old patient, with emphasis on cytomorphologic features and clues toward this diagnostic entity. Correlating the cytohistologic findings and review of touch imprints revealed that presence of hyaline nodules resembling leisegang rings and psammoma bodies in cytologic smears from kidney tumors serve as an important clue in raising a suspicion for the diagnosis of MiT family translocation RCCs...

OBJECTIVE: Conventional smear (CS) using fine-needle aspiration cytology (FNAC) has been established as the test of choice for diagnosing thyroid lesions, despite low sample adequacy and inter-individual variations. Although a liquid-based preparation (LBP) technique has been recently applied to overcome these limitations, its clinical utility and its accuracy over CS are controversial. This study aimed to determine the true sensitivity and specificity of LBP in thyroid FNAC by meta-analysis...

Granular Cell Tumours (GCTs) are uncommon tumours which can be confused with other benign soft tissue tumours on clinical examination. Fine Needle Aspiration Cytology (FNAC) plays a significant role in their diagnosis. There are certain cytological mimickers of GCTs so a cytopathologist must be aware of its characteristic cytomorphology. These tumours can be present anywhere on the body; however, chest wall is one of the uncommon sites. We present a case of GCT present on the chest wall in an elderly male as a subcutaneous nodule...
