AMOEBOMA Meaning and
Definition
-
Amoeboma is a medical term used to describe a localized mass or tumor-like growth that arises due to chronic infection caused by the protozoan parasite known as Entamoeba histolytica. This condition typically occurs in the large intestine, particularly in the colon, and it is considered a complication of the more severe form of amoebic dysentery. An amoeboma is the result of chronic inflammation and hyperplasia, which causes the affected area to become thickened and form a mass.
The development of an amoeboma occurs when the body's immune response tries to contain the infection by forming granulomas in the colon wall. These granulomas are clusters of immune cells that attempt to surround and isolate the parasite. However, over time, the immune response becomes exaggerated, leading to the formation of a distinct mass. This mass can cause various gastrointestinal symptoms such as abdominal pain, changes in bowel habits, and rectal bleeding.
Diagnosing an amoeboma usually involves a combination of clinical history, examination, and laboratory tests, including stool samples to identify the presence of the Entamoeba histolytica parasite. Imaging studies such as computed tomography (CT) scans or colonoscopies may also be utilized to visualize the affected area and confirm the diagnosis.
Treatment of amoeboma typically involves a combination of medication, such as antibiotics, to eradicate the underlying infection, followed by surgical intervention to remove the mass. In some cases, a colostomy may be necessary to bypass the affected area temporarily.
Overall, amoeboma is a rare condition that results from chronic infection with Entamoeba histolytica and presents as a localized growth in the large intestine. It requires prompt medical attention and a multidisciplinary approach for effective management.
Etymology of AMOEBOMA
The term "amoeboma" is derived from a combination of two words: "amoeba" and "oma".
1. "Amoeba" originates from the Greek word "amoibḗ", which means "change" or "revolution". The word was first used to refer to single-celled organisms that have an ever-changing shape or constantly change their position. It was later adapted into Latin as "amoeba".
2. "Oma" is a suffix in medical terminology derived from Greek, indicating a tumor or abnormal mass. It is used to describe swelling or a tumor-like growth in a particular organ or tissue.
Therefore, "amoeboma" combines "amoeba" and "oma" to describe a tumor-like growth or mass caused by an infection with amoebas, particularly the parasite Entamoeba histolytica.
