General and Systemic Histopathology, C601&C602
     
    Neoplastic Processes

    In this laboratory, we are looking at the principal differences between cells that exhibit normal cell growth and those that have unregulated or altered growth. It's not the purpose to study the individual malignancies, rather the process and general histological appearance. The term "neoplasia" does not necessarily imply malignancy. It simply means "new growth," and it applies to both benign and malignant processes. When finished with this laboratory, you should know what it is meant by the terms: metaplasia, dysplasia and malignancy. When dealing with the cytological aspects of malignant cells, we talk about the nuclear/cytoplasmic ratio as well as various degrees of nuclear hyperchromasia and angulation of the nuclear margins, nuclear molding as well as the mitotic count. These are more terms you will need to be familiar with. On the histological level, you will encounter terms such as: gland within gland. Be sure you can define terms such as carcinoma, sarcoma and adenocarcinoma. You will learn more specific terms as they apply to the individual systems as we work our way through the course.
