Cytology‐First Diagnostic Workflow for Melanoma of Unknown Primary With Molecular Profiling

Cytopathology, EarlyView.
Cytology‑first diagnostic workflow for melanoma of unknown primary. Fine‑needle aspiration of an enlarged lymph node enables rapid cytologic evaluation and immunocytochemical confirmation of melanocytic lineage (SOX10). This early cytologic diagnosis facilitates timely surgical excision and comprehensive genomic profiling, supporting integrated ...

Diagnostic and Prognostic Value Of Ki67 Proliferation Fraction in Serous Effusions

Cellular Oncology, 2004
The Ki67 proliferation rate of mesothelial cells was determined in 20 effusions due to malignant mesotheliomas and in 20 non‐neoplastic effusions, to investigate if this marker may be useful to identify neoplastic mesothelioma cells and if there is a ...

A Unified Deep Learning Framework for Instance Segmentation Across Diverse Cytological Stains

Cytopathology, EarlyView.
Transformer‐based unified cytology segmentation across Papanicolaou, Feulgen and AgNOR achieves stain‐invariant performance. Mask2Former maximises boundary precision (AP75) on the combined dataset, enabling one model to replace multiple stain‐specific deployments without accuracy loss while simplifying clinical integration.

The Impact of Change in Practicing Cytopathologists' Team on Risk of Malignancy in a Retrospective Single‐Centre Project of 652 Thyroid Nodules: A Quality Assurance Project

Cytopathology, EarlyView.
This quality assurance project confirms that thyroid FNAC is a reliable tool for assessing the risk of malignancy (ROM), with ROM rates aligning with published data. However, cytology team changes can reveal interobserver variability and shift category distribution and malignancy rates, underlining the need for ongoing quality assurance and training ...
