Pleural and Peritoneal Fluids Cytology

Pleural and Peritoneal Fluids Cytology is an advanced tertiary-level topic for Zambian university students in Biomedical Sciences, Pathology, and related health degree programs. This module focuses on the cytological evaluation of effusions to detect malignant cells, which is crucial for staging cancer and diagnosing primary mesothelial tumors like mesothelioma. Students learn to identify benign reactive mesothelial cells, macrophages, and differentiate them from metastatic adenocarcinoma, squamous cell carcinoma, and malignant mesothelioma. Key diagnostic features such as cell arrangement, nuclear characteristics, and the presence of windows or lacy skirts are emphasized. In Zambia, where infectious etiologies of effusions are common, the ability to accurately identify malignant cells prevents misdiagnosis and guides appropriate oncology referrals. This topic prepares learners for complex diagnostic challenges, enhances their performance in tertiary examinations, and builds expertise for careers in cytology, oncology, and serous fluid analysis within national and regional healthcare laboratories.
