**1. Introduction**

Krukenberg tumors account for less than 2% of all ovarian carcinomas and represent ovarian metastases that usually originate from mucosecretory signet ring cell adenocarcinomas of the gastrointestinal tract. The most commonly encountered sites are the stomach and the colon [1–3]. In less common situations, Krukenberg tumors originate from other primaries such as the breast, small intestine, and appendix [3]. For lung cancer ovarian metastases, data are even scarcer, with only a few

cases being reported so far [4–6]. Most often, these cases are represented by pulmonary adenocarcinomas (in up to 45% of cases), and the exact mechanism of development is not well understood [6]. The aim of this paper is to report the case of a patient diagnosed with Krukenberg tumor and peritoneal carcinomatosis invading the right ureter originating from pulmonary adenocarcinoma, in which the final diagnostic was established after performing a laparoscopic adnexectomy.
