INTRODUCTION: Fine needle aspiration biopsy (FNAB) is a routinely used investigation in the evaluation of lymph node pathologies. However, there exists a lack of uniformity in cytopathology reporting owing to the non-availability of standard guidelines. Recently, a novel system for reporting lymph node cytopathology has been proposed. The present study aimed to analyze the utility of the proposed system in cytopathology reporting in our institution. MATERIALS: FNAB of lymph nodes performed over a period of 5 years were categorized as per the proposed Sydney system...

BACKGROUND: The tumors involving the gynecologic tract encompass a wide range of lesions including those of epithelial, mesenchymal, sex cord-stromal, and germ cell origin. Amongst the carcinomas of tubo-ovarian origin, high-grade serous carcinoma is the most common malignancy. The primary role of fine needle aspiration (FNA) cytology in the management of gynecologic tract malignancies is in the diagnosis of their recurrences/metastases. In patients presenting with advanced disease, the cytology specimen may be the initial or the only sampling performed before the initiation of treatment...

INTRODUCTION: In most cases the diagnostic workup of pleural mesotheliomas (MPM) starts with cytological examination of pleural effusion, but histology is needed to confirm the diagnosis. The introduction of BAP1 and MTAP immunohistochemistry have become a powerful tool to confirm the malignant nature of mesothelial proliferations also in cytological specimens. The objective of this study is to determine the concordance of BAP1, MTAP and p16 expression between cytological and histological samples of patients with MPM...

Introduction Volume recommendations of 80-200ml have been proposed for peritoneal fluid cytology. While cut-offs are impractical when volume is limited by the amount present and disease factors, collections, however, can be repeated. This study addresses adequacy and number needed to diagnose by comparing diagnostic agreement to volumes in single specimens, total volumes collected daily, and within admissions. The diagnostic yield of repeating collection within a single day, admission, and throughout admissions of a patient's lifetime was also investigated...

INTRODUCTION: Cytological samples from cutaneous melanoma (CM) metastases may be the only biomaterial available for diagnostic and predictive purpose in the clinical practice. BRAF evaluation from cytological samples actually implies the loss of one or more diagnostic smears, or the execution of one or more passes to obtain dedicated cytological samples. We tested BRAF molecular evaluation in CM metastases on cell suspension obtained from fine needle aspiration cytology (FNAC) needle rinses...

BACKGROUND: Squamous intraepithelial lesions observed in Papanicolaou (Pap) test gynecologic cytology arise as a result of infection of the cervicovaginal tract by human papillomavirus (HPV). The viral cytopathic effect of HPV manifests as koilocytosis, also known as low-grade squamous intraepithelial lesion (LSIL) in The Bethesda System (TBS). Integration of HPV genetic material into the genome of squamous cells can, in some women, result in progressive accumulation of mutations and abnormalities of growth and maturation leading to high-grade squamous intraepithelial lesion (HSIL) and possibly invasive squamous cell carcinoma...

BACKGROUND: Up until recently, cervical cytology was the mainstay for cervical cancer screening. However, the established association between human papillomavirus (HPV) infection and cervical cancer has led to changes in preventive strategies with cytology being replaced by the use of high risk HPV (hrHPV) testing and primary prevention being achieved by HPV vaccination. In this context, the role of cervical cytology is shifting to secondary triage of HPV positive women. As vaccination is leading to decreased HPV infections and significant cervical abnormalities (CIN2+), data on the impact of HPV vaccination of cervical cytology metrics, including positive predictive value (PPV) and negative predictive value (NPV) is starting to emerge...

INTRODUCTION: Identifying metastatic breast carcinoma (mBC) in malignant effusion cytology (MEC) specimens is critical, as this will determine the patient's prognosis and therapeutic management. Overlapping cytomorphologic features of breast carcinoma (BC) with other neoplastic entities makes the use of sensitive and specific markers highly desirable. Recent studies have reported trichorhinophalangeal syndrome type 1 (TRPS1) as a sensitive and specific marker for primary BC and mBC. We aimed to investigate TRPS1 expression in MEC of mBC and its most common diagnostic mimickers...

INTRODUCTION: Anaplastic large cell lymphoma (ALCL) is a rare mature T-cell non-Hodgkin's lymphoma characterized by large and pleomorphic neoplastic CD30-positive T cells. ALCL includes different subtypes with different clinical and biological features: systemic ALCL, primary cutaneous ALCL, breast implant-associated ALCL (BIA-ALCL). Anaplastic lymphoma kinase (ALK) is overexpressed and rearranged in some systemic cases. Diagnosis of ALCL may be challenging on cytological samples, but the correct diagnosis is mandatory for the management of the patient...

INTRODUCTION: Malignant serous effusions are common in metastatic carcinomas. Although cytomorphology is recognized as the gold standard diagnostic method, it exhibits moderate sensitivity. This study aimed to assess the diagnostic value of immunophenotyping with a single epithelial marker, known as the epithelial cell adhesion molecule (EpCAM, CD326), in discriminating malignant metastatic carcinomas of serous fluids. METHODS: This prospective study was conducted on suspicious or confirmed cases of malignant tumors from September 16, 2019, to June 21, 2020...

BACKGROUND: Pelvic washing and peritoneal fluid cytology specimens are used to detect peritoneal spread of malignancies. In most cases, identification of malignancy in these specimens is straightforward, but benign processes may occasionally mimic neoplasia and cause diagnostic difficulty. SUMMARY: In this article, we perform a focused review of common benign entities encountered in pelvic washing and peritoneal fluid specimens during routine practice which may cause difficulty and discuss helpful features for avoiding diagnostic pitfalls...

BACKGROUND: The incidence of anal cancer has increased over at least the past decade, with estimates of a continued increase in the coming years. Women are more commonly affected than men in the general population; separate high-risk populations have also been identified. While the pathophysiology of anal cancer is thought to be similar to its cervical counterpart, well-defined and standardized screening guidelines have not been established as is seen in cervical cancer prevention. Nonetheless, multiple screening modalities have been examined and are components of proposed institutional and societal screening programs...

The role of cytopathology in the diagnosis, management, and follow-up of patients with gynecologic neoplasms has expanded tremendously since the introduction of the Papanicolaou test, more than 50 years ago. Evidently, advances in HPV testing have revolutionized cervical cancer screening, which now faces new challenges in the setting of increasingly available HPV vaccines. In addition, recent changes in gynecologic tumor nomenclature and staging of gynecologic neoplasms have introduced challenges specific to cytopathology, which if not taken into consideration, might lead to incorrect diagnoses, confusion on the part of the patients and their clinical teams, and potentially suboptimal patient care...

BACKGROUND: The association between high-risk serotypes of human papillomavirus (hr-HPV) and cervical cancer is well-established. SUMMARY: In order to improve the sensitivity of cervical cytology testing, hr-HPV testing has rapidly become part of routine cervical cancer screening, either in conjunction with cytology or as primary testing. In this review, we discuss the overall utility and strategies of hr-HPV testing, as well as the advantages and limitations of potential triage strategies for hr-HPV positive women, including HPV genotyping, p16/Ki-67 dual staining, and methylation assays...

INTRODUCTION: Chondroblastoma (CB) is a rare, benign cartilage-producing tumor, typically affecting the epiphysis of long bones in skeletally immature individuals. There have been only limited case reports describing the cytomorphologic features of this tumor, and thus the cytopathologic diagnostic criteria are controversial. Herein, we report the cytologic findings of 10 CB cases, discuss the diagnostic criteria and critical differential diagnosis, along with a comprehensive review of the literature...
