What is a condition characterized by the implantation of a fertilized egg outside the uterus?

Ectopic pregnancy is defined as the implantation of a fertilized egg outside of the uterus, most commonly occurring in the fallopian tubes. This condition poses significant health risks, as the developing embryo grows in an area not equipped to support its growth, potentially leading to tube rupture, severe bleeding, and life-threatening complications for the individual. In contrast, endometrial carcinoma refers to cancer of the endometrial lining of the uterus, which is unrelated to the implantation location of a fertilized egg. Fibroid tumors are benign growths within the uterus itself that do not involve an ectopic implantation scenario. Gestational trophoblastic disease involves abnormal growth of cells inside the uterus but, again, does not pertain to ectopic implantation. Therefore, the identification of ectopic pregnancy accurately represents the condition characterized by a fertilized egg implanting outside the uterine cavity.
