Define neoplasia and differentiate between parenchyma and stroma in the context of tumor components.
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.
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.

What is neoplasia?
What is neoplasia?
Neoplasia is a disorder of cell growth, leading to abnormal tissue formation. It can be either benign (non-cancerous) or malignant (cancerous).
Parenchyma vs. Stroma in a tumor
Parenchyma vs. Stroma in a tumor
Parenchyma is the neoplastic tissue – the original tissue that's growing abnormally. Stroma is the surrounding normal tissue that supports the parenchyma's growth.
How are benign tumors named?
How are benign tumors named?
Benign tumors are named based on the cell type they originate from, with the suffix '-oma' added. For example, adenoma is a benign tumor of glandular tissue.
How are malignant tumors named?
