What Is Histopathology & Cytology In Angola?
Histopathology and Cytology are crucial diagnostic disciplines within Anatomic Pathology, focusing on the microscopic examination of biological tissues and cells, respectively. These services are indispensable for the diagnosis, staging, and prognostication of a wide array of diseases, with a particular emphasis on neoplastic processes, inflammatory conditions, and infectious diseases. In Angola, as globally, these disciplines are fundamental to patient care, guiding therapeutic decisions and impacting public health initiatives. Histopathology involves the processing of surgically resected specimens or biopsies, encompassing macroscopic examination, tissue fixation, embedding in paraffin wax, sectioning into thin slices, staining (most commonly Hematoxylin and Eosin), and subsequent microscopic evaluation by a pathologist. Cytology, conversely, examines individual cells or small clusters of cells obtained from various bodily fluids (e.g., urine, pleural fluid, cerebrospinal fluid) or via fine-needle aspiration (FNA) or exfoliative cytology (e.g., Pap smears). The analysis involves preparing these samples onto glass slides (e.g., liquid-based cytology, direct smear), staining (e.g., Papanicolaou stain, Giemsa stain), and microscopic assessment. The integration of both disciplines provides a comprehensive understanding of pathological changes at the cellular and architectural levels.
