Contribution of BAP1 loss and p16 (CDKN2A) deletion analysis to the definitive diagnosis of mesothelioma in effusion cytology

European Review for Medical and Pharmacological Sciences 2023 October [Link] G Aydogdu, S Özekinci Abstract Objective: The cytological diagnosis of mesothelioma is a controversial issue, and definitive diagnosis often requires ancillary tests. The aim of this study was to investigate the contribution of BRCA1-associated protein (1) (BAP1) loss and p16 (CDKN2A) homozygous deletion (HD) on…

Malignant mesothelioma cells with characteristic intracytoplasmic vacuolization and lipids

Diagnostic Cytopathology 2023 August 15 [Link] Satoshi Morito, Hiroshi Yasui, Tomoo Itoh, Shingo Kamoshida, Hiroyuki Ohsaki Abstract In this brief report, we described some uncommon cytomorphological features of malignant mesothelioma (MM) cells in pleural effusions. The tumor cells exhibited abundant cytoplasmic vacuolization, with presence of single or multiple eccentric nuclei in several cells. In the…
