Core Tip

Core tip: We describe a patient with endometriosis of the duplex appendix, small intestine, and ovary. There are no similar cases reported. Currently, the diagnosis of duplex appendix and endometriosis is difficult before surgery. Our case suggests that serum carbohydrate antigen 125 levels and fecalith of the appendix may be useful signs for the diagnosis of endometriosis and duplex appendix, respectively. However, the most important procedure is the careful exploration of the abdominal cavity during surgery. Serious legal disputes can occur due to neglecting another infected appendix or not carefully exploring other parts of the abdominal cavity.
