Pseudo-Meigs' syndrome caused by a uterine leiomyosarcoma: a new clinical condition.

INTRODUCTION Pseudo-Meigs' syndrome is a rare condition characterized by female genital cancer, ascites, hydrothorax and tumors other than benign ovarian tumors. CASE REPORT A 30-year-old woman arrived at our clinic with pelvic pain and dyspnea. She underwent an exploratory laparotomy for a large pelvic mass complicated by ascites and hydrothorax. Cytological examination of the effusions was negative for malignant cells. Histological analysis of the tumor mass revealed a uterine epithelioid leiomyosarcoma. After surgery, we observed resolution of the effusions. CONCLUSION Uterine leiomyosarcoma and pseudo-Meigs' syndrome are two rare entities. To our knowledge, there are no similar reports in the literature, and therefore we present this new clinical condition due to its high scientific evidence.
