Background: Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is extremely rare, and its biological behavior, pathogenesis, optimum treatments, and prognosis remain to be elucidated. We herein report a case of PRMC with an 80-month follow-up.
Case Presentation: A 29-year-old woman was diagnosed with unknown retroperitoneal tumor with benign right ovarian cyst and uterine fibroids, and she underwent laparotomy. The tumor was completely resected with a subsequent histopathological diagnosis of primary retroperitoneal mucinous cystadenocarcinoma (PRMC). Eighty months after surgery, she remains recurrence-free.
Conclusion: PRMC is an extremely rare tumor. Only around 60 cases have so far been published in the literature. The preoperative diagnosis of PRMC is difficult, and a definitive diagnosis can usually only be made based on the findings of histopathological examinations after surgery. Presently, only radical resection is useful for both diagnostic and therapeutic purposes. The optimal long-term management after surgery is still not well established. Further studies on PRMC are therefore needed to elucidate the etiology and establish effective treatments.

Background: Metastatic retroperitoneal lymph node dissection (LND) for nodal recurrence is applied for a variety of cancers, such as urological, gynaecological and rectal cancer. Precise localisation and resection of these lymph nodes (LNs) during surgery can be challenging, especially after previous radiotherapy or surgery. The objective of this study was to assess the added value of surgical navigation for targeted LND in the retroperitoneum.

Objective: During the treatment of ovarian cancer, the risk of venous thromboembolism (VTE) post operatively is well established, however, patients may be at even greater risk during neoadjuvant chemotherapy (NACT). This study aimed to determine the incidence and timing of VTE amongst patients undergoing NACT, whether there was an association with survival, and examine risk factors associated with the development of VTE.
Study Design: This was a retrospective cohort study of patients diagnosed with ovarian, fallopian tube and primary peritoneal cancer receiving neoadjuvant chemotherapy betweenApril 2011 and April 2022 at a gynaecological cancer centre in England.

With improved surgical outcomes for non-ruptured abdominal aortic aneurysm (AAA), the primary objective has shifted toward the detection of asymptomatic AAA. Since ultrasonographic visualization from the anterior abdominal wall is often obstructed by intestinal gas, utilizing additional bilateral posterior approaches via the retroperitoneal tissue may be beneficial. This study investigates the feasibility of assessment using three approaches through computed tomography (CT) data analyses.

Primary retroperitoneal seminoma is an exceedingly rare type of germ cell tumor, accounting for less than 5% of all such tumors. These tumors are typically large at presentation due to their slow growth and the nonspecific nature of symptoms, which often leads to delayed diagnosis. A 40-year-old male presented with intermittent abdominal pain and a palpable lump in the right paraumbilical region.
