“…Serum tumor markers, including CA 19-9 and carcinoembryonic antigen were within normal limits, and CA125 was elevated. Similarly, Tani A et al [ 12 ] reported a 78-year-old women with a 35-cm-diameter solid tumor in the peritoneal cavity. Elevated levels of CA125 and HE4 raised suspicions of ovarian malignancy.…”

“…They can be either malignant or benign, with malignancies being more prevalent . [ 11 ] Malignant retroperitoneal tumors may include primary liposarcoma, [ 12 ] epithelioid sarcoma, [ 13 ] malignant mesenchymal tumors, or metastatic tumors, primarily from the spread of germ cell tumors. [ 14 ] On the other hand, benign retroperitoneal tumors are exceptionally rare.…”

“…Diagnosing retroperitoneal tumors can be challenging due to their rarity and atypical clinical features, leading to potential misdiagnoses. [ 12 , 19 , 32 ] Geetha SD et al [ 32 ] reported a case of a retroperitoneal mucinous cystadenocarcinoma in a 54-year-old female presenting with right flank pain. Imaging revealed an 8.6 × 7.9 cm mass on the anterior surface of the lower pole of the right kidney, initially suspected as renal cell carcinoma.…”

Rationale: Retroperitoneal benign cysts during pregnancy are extremely rare and often remain asymptomatic until they attain a very large size. Diagnosis typically relies on a pathological tissue biopsy. The decision to pursue 1-step or 2-step surgical treatment should be tailored to each individual case rather than generalized. Patient concerns: This case report presents the unique scenario of a pregnant woman with a confirmed pregnancy complicated by a large retroperitoneal cyst. The patient had a retroperitoneal cyst during her initial pregnancy, which went undetected during the first cesarean section. However, it was identified during her second pregnancy by which time it had grown to 13.0 cm × 15.0 cm × 25.0 cm, and extended from the liver margin to right ovarian pelvic infundibulopelvic ligament. Consequently, it was removed smoothly during her second cesarean section. Diagnoses: Postoperative pathology results indicated a massive retroperitoneal mucinous cystadenoma. Interventions: The giant retroperitoneal cyst was smoothly excised during the second cesarean delivery for 1-step surgical treatment. Outcomes: Under the combined spinal and epidural anesthesia, a live female infant was delivered at 38 3/7 gestational weeks and the neonatal weight was 3200g. Under general anesthesia with endotracheal intubation, the giant retroperitoneal cyst was excised smoothly without complications. Lessons: The findings of this case report contribute to the understanding of the diagnostic modalities, surgical approaches and postoperative considerations of giant retroperitoneal cysts associated with pregnancy.

Background Liposarcoma originating from peripancreatic fat tissue is extremely rare. This case report presents a surgical case of a giant liposarcoma originating from peripancreatic fat tissue with origin identification using 3-Dimensional Computed Tomography Angiography (3D-CTA). Case presentation A 59-year-old female was referred to our hospital with a giant abdominal tumor. Computed tomography revealed a 34 cm tumor composed of fatty tissue, exerting pressure on the posterior aspect of the pancreas. Suspecting liposarcoma, we planned for surgery. At first, the tumor appeared to be intra-abdominal tumor, based on the identification of the tumor’s feeding artery as a branch of the dorsal pancreatic artery using 3D-CTA, we concluded that the liposarcoma originated from the peripancreatic fat tissue and situated in the retroperitoneum. During surgery, we observed a well-capsulated, elastic, yellowish mass without infiltration into surrounding tissues. We carefully dissected the tumor from the greater omentum and transverse mesocolon while preserving the tumor capsule. We ligated the feeding artery at the border with the pancreatic parenchyma and successfully completed the excision of the tumor. The resected specimen weighted 2620 g and was pathologically diagnosed as a well-differentiated liposarcoma. There was no injury to the tumor’s capsule, and the surgical margins were negative. Conclusions In this report, we present an extremely rare case of a liposarcoma originating in the peripancreatic fat tissue. The use of 3D-CTA was instrumental in identifying the primary site of this giant tumor, enabling us to guide the surgery and achieve complete resection successfully.
