MEDULLARY NEOPLASMS Meaning and
Definition
-
Medullary neoplasms refer to a type of tumors that originate in the medulla, which is the central region of certain organs or tissues. These neoplasms are characterized by abnormal cell growth and proliferation in the medullary tissue. Medullary neoplasms can occur in various parts of the body, including the adrenal glands, thyroid gland, and the kidney.
In the context of adrenal glands, medullary neoplasms can lead to the development of pheochromocytomas, which are tumors arising from chromaffin cells. Pheochromocytomas typically produce excessive amounts of adrenaline and noradrenaline hormones, leading to symptoms such as high blood pressure, palpitations, headaches, and sweating.
In the thyroid gland, medullary neoplasms are often associated with a specific type of cancer called medullary thyroid carcinoma (MTC). MTC arises from parafollicular C cells, which are responsible for the production of calcitonin hormone. These tumors can be sporadic or hereditary, and diagnosis often involves the measurement of calcitonin levels in the blood.
Medullary neoplasms can also occur in the kidney, giving rise to a type of kidney cancer known as medullary renal cell carcinoma (MRCC). MRCC is a rare and aggressive form of kidney cancer that originates from the cells of the renal medulla. Its diagnosis usually involves imaging tests such as CT scans and biopsies to assess tumor characteristics.
Treatment options for medullary neoplasms vary depending on the specific location of the tumor and its stage. Surgical removal is often the primary approach, along with other therapies like radiation, chemotherapy, or targeted drug treatments. Genetic testing may also be recommended

Etymology of MEDULLARY NEOPLASMS
The term "medullary neoplasms" is a medical term that refers to tumors or abnormal growths in the medulla, which is the innermost part of an organ.
The word "medullary" is derived from the Latin word "medulla", which means "marrow". In anatomy, "medulla" is used to describe the innermost or central parts of organs, such as the medulla oblongata in the brain or the renal medulla in the kidney.
The word "neoplasms" comes from the Greek roots "neo-" meaning "new" and "plasma" meaning "formation" or "growth". In medical terminology, "neoplasm" is a general term for an abnormal growth or tumor that occurs as a result of uncontrolled cell division.
