Which condition is defined as ectopic endometrial tissue that can attach to the fallopian tube, ovaries, colon, and bladder?

• A. Endometriosis
• B. Polyp
• C. Krukenberg tumors
• D. Meckel diverticulum

Answer: (A)

Endometriosis is the condition described. It involves endometrial tissue, which normally lines the uterus, being located outside the uterus and able to attach to nearby structures such as the fallopian tubes, ovaries, colon, and bladder. Because these implants respond to hormonal cycles, they can cause pelvic pain, inflammation, and scar tissue, and they may form ovarian endometriomas. The other options don’t fit: a polyp is a benign mucosal outgrowth, Krukenberg tumors are metastatic cancers to the ovaries, and Meckel diverticulum is a congenital pouch in the small intestine. Endometriosis best explains ectopic endometrial tissue on those pelvic structures.
