Gray zone Bethesda category III - Atypia of undetermined significance lesions of the thyroid: Potential diagnostic issues and image morphometry as a useful adjunct to cytomorphology.

Objective: Atypia of undetermined significance (AUS) is an indeterminate category which presents a significant challenge for pathologists and clinicians. The management options are dependent on the rate of malignancy for a given populace.

Material And Methods: This is a retrospective analysis of 61 cases of the AUS Bethesda category III with grouping into neoplastic and non-neoplastic according to the histopathology data and clinical follow-up.

Neuroendocrine tumor of the liver in pregnancy: A very rare case report.

Neuroendocrine neoplasms (NENs) of the liver represent a rare entity. Amongst this group of uncommon diseases primary hepatic neuroendocrine neoplasm (PH-NEN) represent only 0.3% of all NENs.

Antifungal Susceptibility Profile of Clinical and Environmental Isolates of Aspergillus Species From a Tertiary Care Center in North India.

Introduction: species are ubiquitously found in the environment worldwide and are important causative agents for infection. Drug resistance among species is emerging, hence the present study was undertaken to look for antifungal susceptibility profiles of clinical and environmental isolates of species.

Materials And Methods: During the period from January 2018 to June 2019, a total of 102 isolates (40 clinical, 40 hospital, and 22 community environment) were tested for antifungal susceptibility testing for determination of minimum inhibitory concentration (MIC)/minimum effective concentration (MEC) as per Clinical and Laboratory Standards Institute (CLSI) M38-A3 method for itraconazole, voriconazole, amphotericin B, and caspofungin.

Mucormycosis: Cytomorphological Spectrum in Fine-Needle Aspiration Cytology.

Background: Mucormycosis is a fungal infection that can affect multiple organs. The role of fine-needle aspiration cytology (FNAC) in its diagnosis is not well documented.

Aim: The objective of this study was to describe the detailed cytomorphologic features of mucormycosis on FNAC samples.

A rare case of infection and spontaneous rupture in ovarian mucinous cystadenoma.

Ovarian cysts exhibit variable clinical presentations depending on their size, type and resulting sequelae. Rupture of ovarian cysts is infrequent, and cyst infections are even rarer. Here, we report an unusual case involving a young, non-pregnant woman who presented acutely with features of peritonitis and sepsis and was found to have a complex adnexal mass.

The WHO system versus the Papanicolaou society of cytopathology system for reporting pancreaticobiliary cytology for risk stratification-which is better?

Background: Recently, the World Health Organization (WHO) has proposed a reporting system for pancreaticobiliary cytopathology. We applied this classification for pancreatic lesion samples by fine needle aspiration (FNA) and compared the results to the previous classification of the Papanicolaou Society of Cytopathology (PSC) system for risk stratification.

Methods: The computerized database was searched for all pancreatic endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and transabdominal ultrasound-guided FNA (TUS-FNA) samples from 2016 to 2020 and cases were reassigned as per the PSC and the WHO diagnostic categories.

Opportunistic microsporidiosis unveiled by fine-needle aspiration cytology of cervical lymph node with literature review.

Microsporidia are highly specialized obligate intracellular organisms closely related to fungi, traditionally linked to diarrheal diseases in acquired immunodeficiency syndrome patients. Over the past two decades, an increasing incidence of extraintestinal infections affecting various organ systems, especially in immunocompromised individuals, has been observed. The report presents a unique case of lymph node microsporidiosis in a 38-year-old male, positive for human immunodeficiency virus, with coinfections of hepatitis B and C.

Artificial Intelligence: Exploring utility in detection and typing of fungus with futuristic application in fungal cytology.

Artificial Intelligence (AI) is an emerging, transforming and revolutionary technology that has captured attention worldwide. It is translating research into precision oncology treatments. AI can analyse large or big data sets requiring high-speed specialized computing solutions.

Cytomorphologic and immunocytochemical characterization of pediatric pleuropulmonary blastoma with a comprehensive review of the literature.

Introduction: Pleuropulmonary blastoma (PPB) is a rare, aggressive, primary intrathoracic malignancy typically seen in infancy and early childhood. Accurate distinction from congenital cystic lung lesions is crucial due to significant prognostic and therapeutic differences. Cytologic features have rarely been described.

Metastasis of solitary fibrous tumor to the parotid gland diagnosed on aspiration cytology supplemented with immunocytochemistry.

Solitary fibrous tumor (SFT) can occur in varied anatomic locations, most commonly being the extremities-superficial and deep soft tissues, followed by retroperitoneum, visceral organs, and the bone. Head and neck region may harbor a few with a predilection for the orbit and sinonasal tract, oral cavity, and rarely the salivary glands. The parotid gland is most involved among all salivary glands.

Primary leiomyosarcoma of the parotid gland: Aspiration cytology with emphasis on differential diagnosis.

Most salivary gland neoplasms are of epithelial origin. Sarcomas of the parotid gland, including leiomyosarcoma, are exceedingly rare mesenchymal tumours. A definitive diagnosis of leiomyosarcoma is challenging on cytomorphology alone.

Cytological spectrum of testicular malignancies with histopathological correlation: A retrospective analysis.

Background: Testicular malignancy is the most common solid organ cancer occurring in young men. The most common testicular malignancy is germ cell tumor. Extragonadal malignancies such as lymphomas are rare.

Effusion cytology of metastatic carcinosarcoma.

Objectives: Carcinosarcomas (CSs) are rare gynecological neoplasms seen in elderly females. These are composed of malignant epithelial and mesenchymal components, which appear as adenocarcinoma and high-grade sarcoma. Effusions are encountered uncommonly in CS.

Sclerosing Perivascular Epithelioid Cell Tumor of the Uterus: A Rare Entity Posing Diagnostic Challenge.

Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal uterine tumor and the histological variant, sclerosing PEComa is exceedingly rare. Sclerosing PEComas preferentially occur in the retroperitoneum and occurrence in the uterine corpus is seldom seen. These tumors pose a diagnostic challenge and need distinction from morphological mimickers such as epithelioid smooth muscle tumors, endometrial stromal sarcoma, and metastatic carcinoma.

EUS-guided FNAC in intra-abdominal lesions: Technique of tissue acquisition, ancillary testing, pearls and perils, and prospects.

Endoscopic ultrasound enables visualization of lesions within and in the vicinity of the gastrointestinal tract. Endoscopic ultrasound guided fine needle aspiration cytology (EUS-FNAC) helps in targeting various luminal and extraluminal lesions both diagnostically and therapeutically. Various intra-abdominal organs amenable to EUS-FNA include the gastrointestinal tract (GIT), pancreas, kidney, adrenal gland, liver, bile duct, gallbladder, spleen, and lymph nodes.

Phaeohyphomycosis: A study from tertiary health care center in North India.

Objectives: Phaeohyphomycosis refers to infections caused by phaeoid/dematiaceous or darkly pigmented fungi. This study was undertaken to further increase our knowledge about the incidence of phaeohyphomycosis and its causative agents.

Materials And Methods: The present study was conducted over a period of one and a half years (January 2018-June 2019) on specimens received from patients with varied clinical manifestations ranging from superficial infections, subcutaneous cysts, pneumonia, brain abscess to a disseminated infection.

Scalp metastasis of pulmonary blastoma-a rare entity: Cytomorphology with differential diagnoses.

Background: Pulmonary blastomas are exceptionally rare tumours. These tumours behave aggressively, with a propensity to metastasise to the brain and mediastinum. A definitive diagnosis of pulmonary blastoma is challenging to obtain on cytomorphology alone.
