A mother cyst, also known as a parent cyst, refers to a large cyst from which smaller cysts may develop. Synonyms for mother cyst include primary cyst, dominant cyst, and source cyst. These terms essentially describe the same phenomenon, where one large cyst gives rise to multiple smaller cysts. The utilization of different synonyms can help healthcare professionals express the same concept in various contexts or research studies. However, regardless of the chosen terminology, the fundamental idea remains constant: a mother cyst serves as the origin or hub from which numerous satellite or daughter cysts ultimately emerge.
