What term describes endometriosis located on the surface of the peritoneum?

• A. Endometriosis
• B. Adenomyosis
• C. Endometrioma
• D. Peritoneal endometriosis

Answer: (D)

Endometriosis describes endometrial-like tissue outside the uterus. When those implants are on the surface of the peritoneum, the specific term for that location is peritoneal endometriosis. The peritoneum lines the abdominal cavity, so superficial implants there are categorized as peritoneal endometriosis. This distinguishes them from adenomyosis, which is endometrial tissue within the uterine muscle, and from an endometrioma, which is ovarian endometriosis forming a cyst. So describing endometriosis located on the peritoneal surface fits peritoneal endometriosis.
