摘　　要：BACKGROUND Duplication of the appendix is an infrequent congenital malformation with a complex classification.The horseshoe appendix is a subtype of the duplex appendix and is rarely reported in the literature.Endometriosis is a common gynecological disease that rarely occurs in the appendix.Moreover,horseshoe appendix combined with endometriosis has not been previously reported.CASE SUMMARY Here,we describe a 44-year-old woman who was admitted with a 1-d history of migratory lower right quadrant pain.Physical examination was consistent with the signs of acute appendicitis.The patient underwent an emergency exploratory laparotomy.The distal tip of the appendix was in contact with the cecum by another base,or“horseshoe appendix”.In addition,a small intestinal mass and an ovarian mass were identified.Subsequently,appendectomy,partial resection of the small intestine,and right oophorectomy were successively performed.The histopathology confirmed the diagnosis of acute inflammation of the duplex appendix with endometriosis,small intestine endometriosis,and ovarian endometriosis.CONCLUSION Surgeons need to be aware of the possibility of the duplex appendix when performing an appendectomy,and this study emphasizes the importance of exploring the entire abdomen.BACKGROUND Duplication of the appendix is an infrequent congenital malformation with a complex classification.
