Histopathology in tropical medicine: a perspective.
Histopathology may serve a wide spectrum of diagnostic purposes in tropical medicine other than for infectious and parasitic diseases. In addition, it is essential in defining new pathological entities and collecting statistical data on morbidity and mortality. It should also constitute a basic support for advancement and research in tropical diseases. For practical purposes, both histopathology and cytopathology are often more effective than clinical chemistry and microbiology in providing the clinician with a final diagnosis. They do not rely on complicated and delicate equipment, and the few reagents they require can be stored indefinitely. Formalin fixation permits most histological methods to be used, including special stains and immunohistochemistry. Formalin-fixed material can be examined several days after excision. Implementing pathology laboratories in tropical countries may constitute a practical, cost-effective approach to the planning of diagnostic services at the regional or district level. A fraction of the medical graduates in developing countries should be devoted to the staffing of these laboratories.
