In cases where semen collection in tom-cats is not possible, FNA of testes is the alternative to evaluate sperm production. Although this technique for the diagnosis of fertility problems has been well discussed in other mammals (men, dogs, stallions), data for domestic cats are limited. Therefore, the aim of this study was to verify the reliability of FNA using needles of small diameters (22G and 29G) in testes of domestic cats of different ages to assess the spermatogenesis status and to present description of germ cells and Sertoli cells for cytological examinations...

BACKGROUND: Inflammatory myofibroblastic tumor (IMT) is a rare, distinctive lesion composed of a proliferation of myofibroblastic spindle cells accompanied by an inflammatory infiltrate. It was first described in the lung, but its occurrence at various extrapulmonary sites has also been reported. The literature mentions only a handful of cases of IMT in the breast and only 1 case in the male breast. We report the second case of IMT in the male breast. CASE REPORT: A 60-year-old male presented with a large, lobulated lump in the left breast that had progressively increased in size during the past year...

Fine-needle aspiration cytology (FNAC) is widely used for diagnosing thyroid nodules. However, there has been no specific investigation about the puncture feeling of grittiness. The aim of the present study was to see if the puncture feeling of grittiness during fine-needle aspiration procedure, combined with standard FNAC, could improve the accuracy in diagnosing thyroid cancer. A total of one thousand five hundred and thirty-one thyroid FNAC specimens acquired between January 2013 and January 2017 were retrospectively retrieved...

Background: FDG-avid thyroid incidentalomas (TI) are seen in approximately 2.5% of patients imaged for staging or response assessment of malignancy and represent thyroid cancer in approximately 35% of cases. Consequently, the 2015 ATA guidelines strongly recommend investigation of all FDG-avid nodules ≥1cm with US and fine needle aspiration cytology (FNA). This study aims to assess the overall and thyroid cancer specific survival in a large cohort of patients with FDG-avid TI with long-term follow-up to assess the validity of this approach...

BACKGROUND: The most common malignant thyroid neoplasm in children is papillary thyroid carcinoma (PTC). In 2015, the Endocrine Pathology Society introduced the terminology "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) to replace the noninvasive follicular variant of PTC. The objective of the current study was to evaluate previously diagnosed PTC in the pediatric population, reappraise it for NIFTP, and discuss the impact of NIFTP on the risk of malignancy (ROM) for each The Bethesda System for Reporting Thyroid Cytopathology category in the pediatric population...

BACKGROUND: There is controversy about the accuracy of the fine-needle aspiration (FNA) cytology results in large sized thyroid nodules. Our aim was to evaluate the false-negative rate of FNA for large thyroid nodules and the usefulness of the Thyroid Imaging Reporting and Data System (TIRADS) in predicting false-negative cytology for large thyroid nodules with benign cytology. METHODS: 632 thyroid nodules larger than or equal to 3cm in size with subsequent benign cytology on US-guided FNA were included...

Spindle cell ductal carcinoma in situ (DCIS) is a recently recognized subtype of DCIS, which is associated with a very rare and unique morphology. Although the histologic features have been relatively well described in a few reports, the cytologic features have not. Even though the distinction of this lesion from usual DCIS is not crucial clinically, it should be noted that this lesion might simulate the features of metaplastic carcinoma on fine needle aspiration cytology. Here, we report a case of spindle cell DCIS in a 45-year-old female, with the detailed cytologic features, both on conventional and liquid-based preparations, along with some useful immunohistochemical staining markers for the differential diagnosis...

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 is controversial. This study aimed to determine the true sensitivity and specificity of LBP in thyroid FNAC by meta-analysis...

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...

Cysticercosis is caused by larval stage of Taenia solium called cysticercus cellulosae. Cysticercosis most commonly infects skeletal muscles, subcutaneous tissues, brain and ocular tissue. On extensive search of literature, only around 64 cases of lingual cysticercosis have been reported till date. We report a case of cysticercosis of tongue in a 35-year-old male who presented with a painless, slowly growing swelling over the lateral border of tongue. Fine needle aspiration cytology revealed wavy integument of cysticercus cellulosae alongwith inflammatory cells...

Fine-needle aspiration (FNA) is a well accepted initial approach in the management of thyroid lesions. It has gone a long way since its introduction for nearly a century. In the Philippines, FNA of the thyroid started 30 years ago and has been utilized until now as a mainstay in the diagnosis of thyroid malignancy. The procedure is performed by pathologists, endocrinologists, surgeons and radiologists. Majority of pathologists report the cytodiagnosis using a combination of the aspiration biopsy cytology method that closely resembles the histopathologic diagnosis of thyroid disorders and the six-tier nomenclature of The Bethesda System for Reporting Thyroid Cytopathology...

Fine needle aspiration cytology (FNAC) is a screening test for triaging thyroid nodules, aiding in subsequent clinical management. However, the advantages have been overshadowed by the multiplicity of reporting systems and a wide range of nomenclature used. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was formulated in 2007, to give the world a uniform thyroid cytology reporting system, facilitating easy interpretation by the clinicians. Here, we review the status of thyroid FNAC in India in terms of various reporting systems used including a meta-analysis of the previously published data...

D Westerwick, F Driever, C H D Le Guin, K W Schmid, K A Metz
Metastatic cancer represents the most common form of intraocular malignancy. Due to its abundant vascular supply the choroid is the most common ocular site for intraocular metastatic disease (approximately 90%). Less than 10% of intraocular metastases are located in the iris and/or ciliary body, whereas the retina and vitreous are rarely affected. Most intraocular metastases are carcinomas; the majority of metastases originate from breast cancer in females and lung cancer in males. However, virtually every primary malignancy has been described to metastasize to intraocular structures...

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...

Pablo Valderrabano, Bryan McIver
In accordance with National Guidelines, we currently follow a linear approach to the diagnosis of thyroid nodules, with management decision based primarily on a cytological diagnosis following fine-needle aspiration biopsy. However, 25% of these biopsies render an indeterminate cytology, leaving uncertainty regarding appropriate management. Individualizing the risk of malignancy of these nodules could improve their management significantly. We summarize the current evidence on the relevance of clinical information, radiological features, cytological features, and molecular markers tests results and describe how these can be integrated to personalize the management of thyroid nodules with indeterminate cytology...

Upper extremity deep vein thrombosis is an extremely important clinical entity with potential for considerable morbidity and mortality. A 64-year-old woman was brought to the emergency department with complaints of left upper limb and neck swelling for 4 days. Ultrasonography of the neck showed thrombosis of the left internal jugular and other surrounding veins associated with local lymphadenopathy. Computed tomography (CT) of the neck also showed a hypodense 0.6 cm × 0.8 cm × 1.2 cm lesion in the right middle lobe bronchus, causing complete occlusion and collapse of the right middle lobe of the lung...
