5 Questions
Define neoplasia and differentiate between parenchyma and stroma in the context of tumor components.
Neoplasia refers to a disorder of cell growth. In the context of tumor components, parenchyma refers to the neoplastic tissue, which is the original tissue (e.g., kidney), whereas stroma refers to the non-neoplastic tissue, the normal tissue available in the body to promote the growth of parenchyma tissue. Stroma is recruited by the tumor to facilitate growth and can include fibroblasts and immune cells, which are recognized as non-self cells.
Explain the nomenclature for naming benign and malignant tumors.
A benign tumor is named based on the type of cell with the suffix '-oma' (e.g., adenoma). On the other hand, a malignant tumor is named based on the type of cell, such as epithelial carcinoma, mesenchymal sarcoma, or glandular adenocarcinoma.
What is an eponymically-named tumor? Provide examples of eponymically-named tumors and their characteristics.
An eponymically-named tumor is a tumor named after a person or place. Examples include Hodgkin lymphoma, which starts in lymphocytes, Wilms tumor (nephroblastoma), and Burkitt's lymphoma, a type of non-Hodgkin's lymphoma that starts in B-cells.
Define pleomorphism, hyperchromasia, and anaplasia in the context of abnormal tissue mass (cancer).
Pleomorphism refers to the change in size and shape of cells, hyperchromasia refers to how much the cell is able to take up stains (darker stains), and anaplasia refers to how well the cells differentiate in the context of abnormal tissue mass (cancer).
Differentiate between benign and malignant tumors based on their types and naming conventions.
Benign tumors are named based on the type of cell with the suffix '-oma' and include adenoma, whereas malignant tumors are named based on the type of cell, such as epithelial carcinoma, mesenchymal sarcoma, or glandular adenocarcinoma. Malignant tumors are more aggressive and have the potential to spread to other parts of the body, while benign tumors are non-cancerous and do not invade nearby tissues or spread to other parts of the body.
