Core Tip

Core Tip: Pseudomyxoma peritonei (PMP) happens rarely. Most of the tumors that occur in PMP are not primary, but secondary to ruptured mucinous tumors of other organs. Existent medical literature shows that the appendix is the most common origin site. However, other origins such as intestinal duplication can occur. The present case report describes a 52-year-old patient with PMP that is derived from a primary intestinal duplication.
