What is meant by neoplastic etiologies?

Neoplastic diseases are conditions that cause tumor growth — both benign and malignant. Benign tumors are noncancerous growths. They usually grow slowly and can’t spread to other tissues. Malignant tumors are cancerous and can grow slowly or quickly.

Does neoplastic mean cancer?

An abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should. Neoplasms may be benign (not cancer) or malignant (cancer).

What are examples of neoplastic?

Examples: Adenoma (benign neoplasm of glandular epithelium), fibroadenoma (benign neoplasm of the breast), and leiomyoma (benign neoplasm of smooth muscle).

What is neoplastic proliferation?

General Concepts. Neoplasia, which literally means “new growth,” is the process of excessive and uncontrolled cell proliferation (Kumar et al., 2010). The new growth is called a neoplasm or tumor (i.e., a swelling, since most neoplasms are expansile, solid masses of abnormal tissue).

What is a mucinous neoplasm?

Mucinous neoplasms of the appendix are a complex, diverse group of epithelial neoplasms often causing cystic dilation of the appendix due to accumulation of gelatinous material, morphologically referred to as mucoceles.

What are neoplastic cells?

Neoplasia is new, uncontrolled growth of cells that is not under physiologic control. A “tumor” or “mass lesion” is simply a “growth” or “enlargement” which may not be neoplastic (such as a granuloma). The term “cancer” implies malignancy, but neoplasms can be subclassified as either benign or malignant.

What is the difference between a neoplasm and a tumor?

The difference between a tumor and a neoplasm is that a tumor refers to swelling or a lump like swollen state that would normally be associated with inflammation, whereas a neoplasm refers to any new growth, lesion, or ulcer that is abnormal.

What is neoplastic proliferation of white blood cells?

Neoplastic Proliferation of WBCs Lymphoid disorders include acute precursor lymphoblastic leukemias (ALL) and mature B-, T-, and NK-cell neoplasms. Myeloid disorders include acute myeloid leukemias, myeloproliferative neoplasms, and myelodysplastic syndromes.
