Case in brief
A 48-year-old male with a 13-year history of recurrent myxoid liposarcoma presented with significant abdominal distension due to a massive abdominopelvic mass measuring 352 mm. Following imaging, he underwent complete surgical resection of the tumor, which was confirmed as myxoid liposarcoma. Despite the successful surgery, he developed multiple abdominopelvic metastases 18 months later, highlighting the aggressive nature of the disease.
What made this case unusual
The tumor was exceptionally large, measuring 43 × 32 × 23 cm and weighing approximately 20 kg, which is notable for a recurrent retroperitoneal liposarcoma.
Diagnostic / clinical pearl
Clinicians should be aware that even large recurrent tumors may be surgically resectable, but the risk of aggressive recurrence remains significant.
Why it matters
This case emphasizes the importance of long-term postoperative surveillance in patients with a history of myxoid liposarcoma due to the high likelihood of recurrence.
