Giant retroperitoneal dedifferentiated liposarcoma mimicking ovarian cancer: A case report.

Retroperitoneal liposarcoma is a rare tumor, and its dedifferentiated subtype and a larger diameter are associated with a poor prognosis. However, there are few reports of retroperitoneal liposarcomas, both with a dedifferentiated subtype and a diameter of >30 cm. We report a case of a giant retroperitoneal liposarcoma with a dedifferentiated subtype.

Robot-assisted laparoscopic hysterectomy for early-stage endometrial cancer with massive uterine leiomyomas: A case report.

Introduction And Importance: Compared to conventional laparoscopic surgery, robot-assisted surgery enables precise operation, with the aid of high-resolution 3D images and articulated forceps, even in cases where the uterus is very large.

Case Presentation: A 48-year-old woman with severe obesity was referred to our hospital with atypical genital bleeding for half a year. She was diagnosed with multiple uterine leiomyomas and early endometrial cancer with presumed advanced stage classification (stage IA).
