The occurrence of port-site metastasis (PSM) has been reported largely after surgical laparoscopy for gastrointestinal and gynecological carcinomas, mainly ovarian and cervical neoplasia. We present an uncommon case of a port-site metastasis after diagnostic laparoscopy for presumably benign ruptured ovarian cyst, which turned out to be a disseminated intraperitoneal metastasis of a Krukenberg tumor. Although such tumors are rare, every surgeon should be aware of their incidence, especially in relation to the clinical presentation, the younger patient age and peritoneal metastasis of an unknown primary tumor. Since the risk related to PSM after laparoscopic surgery for malignancy still has to be determined, preventive measures should be encouraged when laparoscopy is carried out and intraoperatively ascites or peritoneal carcinosis is being diagnosed.
