Histiocytic sarcoma (HS) is a rare malignant neoplasm showing morphological and immunophenotypic features of mature tissue histiocytes. As HS may mimic non-Hodgkin lymphoma (NHL) pathologically, before the era of immunohistochemistry, many previously reported cases were misdiagnosed NHL. Up to date, there are only a few reports delineating the cytological features in fine-needle aspiration or bronchoalveolar lavage, but not in the effusion fluid yet. Herein, we report the case of a 61-year-old male with a mediastinal tumor presenting with malignant pleural effusion...

OBJECTIVE: Endobronchial ultrasound fine needle aspiration (EBUS FNA) is a well-established procedure for the diagnosis and staging of lung cancer. We review our provision of this service at the Royal Devon and Exeter NHS Foundation Trust and the role of rapid onsite evaluation (ROSE) with the increasing demand for molecular markers in this era of personalized medicine. METHODS: A review of the changes in the Endoscopy clinic over the 7 years from the introduction of EBUS at the end of 2010 until 2017 was carried out...

Carcinoma associated with thyroglossal duct cyst (TDC) is extremely rare and when it occurs it is invariably papillary carcinoma. A 36-year-old man presented with a midline swelling in the upper part of neck, which was a cystic lesion with multiple septae in ultrasonogram, indicating a thyroglossal duct cyst. The CT scan findings also corroborated the ultrasound report. Fine needle aspiration (FNA) smears showed hemosiderin laden cyst macrophages and occasional papillary cluster of neoplastic cells with central psammoma body and rare intranuclear cytoplasmic inclusions...

INTRODUCTION: Two new systems with a novel tip (Procore™ and SharkCore™) have been introduced for ultrasound-guided fine needle biopsy (US-FNB). Direct comparison of the diagnostic yield of these needles in the evaluation of pancreatic lesions is currently under investigation. This study aims to compare the diagnostic and cellular yields of the two needle systems. METHODS: Consecutive patients with upper gastrointestinal lesions undergoing EUS-FNB using 22 gauge Procore™ (reverse bevel) or SharkCore™ (fork-tip) needles were included in the study...

Molluscum contagiosum (MC) is most frequently a self-limiting benign viral skin disease. Transmitted by direct skin contact, it is characterized by flesh-colored, dome-shaped, umbilicated lesions. Diagnosis of MC is often done clinically, but when needed, biopsy can be performed, in which characteristic Henderson-Patterson bodies, representing intracytoplasmic assemblies of the virus, are pathognomonic. Atypical presentations of MC are rare in immunocompetent individuals and are challenging to diagnose. We report a case of giant MC, presenting as an ulcero-proliferative growth, in neck of an 8-month-old female child...

International telecytology can improve patient care by increasing access to regional and international expertise in cytopathology. The majority of international telecytology studies published to date have been based on static telepathology platforms. Overall concordance rates for these studies ranged from 71% to 93%. This is comparable to the concordance rates published for other studies comparing diagnoses made by digital still images to reference glass slides, which vary from 80% to 95%. Static telepathology systems are relatively cheap and easy to use, and have the potential to increase access to international experts in developing countries with limited resources...

Melanotic Xp11 translocation renal cancer is a rare category of MiTF/TFE3 neoplasms morphologically resembling Xp11 translocation renal cell carcinoma, Xp11 translocation perivascular epithelioid cell tumor, and melanoma. The diagnosis requires demonstration of TFE3 gene rearrangement, by either fluorescence in situ hybridization (FISH) at the Xp11.2 locus or by TFE3 immunohistochemistry. As cytology smears can be useful adjuncts in cytogenetic and molecular testing, we demonstrate TFE3 rearrangement by FISH analysis on cytologic smears in melanotic Xp11 translocation renal cancer...

BACKGROUND: The rapid diagnosis of extrapulmonary tuberculosis in children remains challenging. The presence of enlarged lymph nodes provides an opportunity to obtain diagnostic material through fine needle aspiration biopsy (FNAB). Mycobacterial culture, traditionally the reference standard, has a slow turnaround time and PCR-based methods are not widely available in developing countries. Direct visualization of mycobacteria on microscopy can be a rapid method to confirm the diagnosis...

BACKGROUND: Bethesda guidelines do not require presence of transformation zone (TZ) for a cervical Pap test to be deemed adequate. However, clinicians are concerned with specimens that are reported to lack TZ. METHODS: We analyzed 566 ThinPrep cases reported as negative for intraepithelial lesion or malignancy (NILM) with no cervical abnormality detected in previous 4 years (2007-2011). These cases were divided into two cohorts; those with TZ (ETZ) and those without TZ (NTZ)...

OBJECTIVE: Cytomegalovirus (CMV) is a ubiquitous infection typically affecting over 50% of the US population by age 40. We report 8 cases of CMV infections detected in cervical cancer screening tests, the largest series of cases thus far reported in gynecologic cytology specimens. METHODS: A retrospective review of our pathology archival computer database was performed from January 1, 1994 through December 31, 2016 for CMV infections reported in cervical cytology specimens...

Langerhans cell sarcoma (LCS) is an extremely rare malignant dendritic cell neoplasm with Langerhans cell differentiation. Conventional cytology, based on cell morphology alone, cannot render a cytological diagnosis of LCS because immunochemical analysis is essential to identify the Langerhans cell immunophenotype. We present a case illustrating the value of liquid-based cytology with immunocytochemistry as compared with conventional cytology, along with histological and immunohistochemical findings. A 92-year-old woman presented with a 1-month history of progressive right cervical lymphadenopathy...

BACKGROUND: The aim of this study is to investigate and compare the results of digital image analysis in pleural effusion cytology samples with conventional modalities. MATERIALS AND METHODS: In this cross-sectional study, 53 pleural fluid cytology smears from Qaem hospital pathology department, located in Mashhad, Iran were investigated. Prior to digital analysis, all specimens were evaluated by two pathologists and categorized into three groups as: benign, suspicious, and malignant...

Inflammatory myofibroblastic tumor is a tumor of intermediate grade with a low rate of metastasis. The tumor often mimics malignancy. There is sparse literature available describing the cytological findings of this rare condition. It often presents in infancy and childhood as an intra-abdominal mass. Here, we describe the cytological findings of three cases of inflammatory myofibroblastic tumor in infants aged 10 months, 4 months, and 15 months, respectively. While the first two cases are fine needle aspiration cytology (FNAC) smears, the third case is that of an intraoperative imprint cytology...

The development of the Papanicolaou smear test by Dr. George Nicholas Papanicolaou (1883-1962) is one of the most significant achievements in screening for disease and cancer prevention in history. The Papanicolaou smear has been used for screening of cervical cancer since the 1950s. The test is technically straightforward and practical and based on a simple scientific observation: malignant cells have an aberrant nuclear morphology that can be distinguished from benign cells. Here, we review the scientific understanding that has been achieved and continues to be made on the causes and consequences of abnormal nuclear morphology, the basis of Dr...
