Overgrowth of endometrial cells in the lining of the uterus may lead to a(n):

• A. cyst
• B. polyp
• C. fibroid
• D. abscess

Answer: (B)

The overgrowth of endometrial cells in the lining of the uterus is classified as the formation of a polyp. Endometrial polyps are growths that occur on the inner wall of the uterus and can vary in size, characterized by an excess proliferation of endometrial tissue. These polyps can be symptomatic, causing irregular menstrual bleeding or other related issues, and are typically benign.

Cysts, while they can be fluid-filled structures resulting from various processes, do not represent a mass formed by proliferating endometrial tissue. Fibroids, or leiomyomas, are another abnormality but are composed of muscle tissue rather than endometrial cells. Abscesses involve localized infections and the accumulation of pus, which is unrelated to the benign proliferation of cells within the endometrial lining. Therefore, polyps are distinctly identified and associated with the overgrowth of endometrial cells in the uterine lining, making it the correct answer.
