Various types of superficial and deep-seated lesions may occur in the hand, causing concern to the patient and posing diagnostic dilemmas to the clinician. A study was undertaken to evaluate the utility of fine-needle aspiration (FNA) or scraping for the diagnosis of palpable lesions located in the hand. From a clinico-cytologic point of view, lesions were classified as superficial (n = 41) or deep-seated (n = 66), and aspirates were categorized into five groups: benign without specific cytohistologic diagnosis, benign with specific cytohistologic diagnosis, atypical, malignant without specific cytohistologic diagnosis, and malignant with specific cytohistologic diagnosis. Out of 107 cases with aspirates adequate for cytologic evaluation, 85 had histologic correlation; in 22 cases, histologic confirmation was deemed unnecessary because of unequivocal cytologic findings and/or clinical workup. Sensitivity was 90.9%, specificity 100%, and efficacy 98%. Based on these findings, we believe that FNA or scraping may help in the clinical workup of patients with either superficial or deep-seated lesions located in this anatomic region.

Diagnostic Dilemma of Herpes Simplex Virus Type 1 Pneumonia or Colonization: A Case Report.
Infect Drug Resist
October 2024
Department of Pathology, Chi Mei Medical Center, Tainan, Taiwan.
Article Synopsis
- Herpes simplex virus type 1 (HSV1) pneumonia is hard to diagnose due to the lack of standard testing methods, but specific tests like bronchoalveolar lavage can help confirm the infection.
- Patients with high viral loads tend to have worse outcomes and may benefit from antiviral treatments, though responses can vary initially.
- The case of an 80-year-old man illustrates the challenges in managing HSV1 pneumonia, showing the need for careful assessment using clinical signs, imaging, and lab results to make timely treatment decisions.
Ultrasonography-Guided Fine Needle Aspiration Cytology Versus Histopathology: Diagnostic Consistency in Salivary Gland Neoplasms.

Community and Family Medicine, All India Institute of Medical Sciences (AIIMS) Deoghar, Deoghar, IND.
Introduction Salivary gland lesions include a diverse range of histological types and biological behaviors, making accurate diagnosis and effective treatment challenging for specialists. Fine needle aspiration cytology (FNAC) plays a significant role in making preoperative diagnoses and further plans of surgery. In differentiating malignant from benign salivary gland tumors, the diagnostic accuracy of fine needle aspiration cytology (FNAC) is high.

Background: Clonality assessment is currently the major molecular analysis utilized to support the diagnosis of suspicious lymphoid malignancies. Clonal rearrangements of the V-J segments of T-cell receptor G chain locus (TCRγ or TRG) have been observed in almost all types of T neoplasms, such as T-cell-related non-Hodgkin lymphomas and leukemias. At present, the gold standard for clonality evaluation is multiplex polymerase chain reaction (PCR), plus subsequent capillary electrophoresis/heteroduplex analyses, and/or Sanger sequencing.

Article Synopsis
- AICyte's study evaluated its potential to reduce workload in cervical cytology screening by implementing a 50% negative cutoff value across 163,848 cases collected from various hospitals in China.
- Results showed that 98.80% of cases marked as not needing further review by AICyte had negative original diagnoses, with high sensitivity and negative predictive values for identifying lesions.
- The findings suggest that using AICyte could streamline diagnostic processes and decrease the burden on pathologists by categorizing certain cases as negative without further review.
Reporting Pancreatic FNAC using the Papanicolaou System: Still a Diagnostic Challenge.
J Cytol
April 2024
Department of Pathology, Dayanand Medical College and Hospital, Ludhiana, Punjab, India.
Introduction: The Papanicolaou Society of Cytopathology System for reporting Pancreaticobiliary Cytology (PSCPC) is a reliable method to classify pancreatic fine needle aspiration cytology (FNAC) smears. However, it is not without practical problems which can diminish the diagnostic accuracy of the cytological diagnosis.
Aims And Objectives: To determine the diagnostic pitfalls while reporting cytomorphology of pancreatic lesions according to PSCPC on correlating FNAC findings with histopathology.
