A case report of retroperitoneal liposarcoma

Area of Science:

• Oncology
• Surgical Pathology

Background:

• Retroperitoneal liposarcoma is a rare mesenchymal tumor with late-stage symptoms like abdominal mass and pain.
• Early-stage retroperitoneal liposarcoma often lacks specific symptoms, leading to delayed diagnosis.

Purpose of the Study:

• To report a case of retroperitoneal liposarcoma presenting with leukocytosis.
• To highlight the importance of postoperative monitoring for recurrence in retroperitoneal liposarcoma.

Main Methods:

• A 54-year-old female patient with abdominal distension and pain underwent computed tomography and pathological examination.
• Surgical intervention included open retroperitoneal mass excision, left nephrectomy, and ureteral stent placement.

Main Results:

• Postoperative pathological findings confirmed retroperitoneal liposarcoma.
• The patient showed no recurrence during a 7-month follow-up period.

Conclusions:

• Retroperitoneal liposarcoma is highly malignant and prone to recurrence, with radical surgery as the primary treatment.
• Elevated white blood cell counts in these patients may indicate a poor prognosis and increased risk of recurrence.
• Regular postoperative blood routine monitoring is suggested for early detection of recurrence and metastasis.
