This case study presents a rare instance of multicentric liposarcoma, a cancer originating from fat cells, occurring simultaneously in multiple abdominal locations with varying histologic types. The findings highlight the complexity of diagnosing and treating this unusual presentation of retroperitoneal liposarcoma.

Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Retroperitoneal liposarcoma is a rare mesenchymal malignancy, typically presenting as a solitary tumor with a single histologic subtype.
  • This condition arises from connective tissue in the retroperitoneal space.

Observation:

  • A 53-year-old male presented with abdominal pain, distension, and weight loss.
  • Imaging revealed large retroperitoneal and intraperitoneal masses.
  • Surgical resection included a 50 cm retroperitoneal mass, a 15 cm retroduodenal mass, and a cecal nodule.

Findings:

  • Histological analysis confirmed a mixed-type liposarcoma (dedifferentiated and myxoid) in the retroperitoneal mass.
  • The retroduodenal mass and cecal nodule showed well-differentiated liposarcoma.
  • This case demonstrates multicentric and synchronous liposarcoma with diverse histologic types.

Implications:

  • This case expands the understanding of liposarcoma presentation, challenging the typical solitary and unilocular nature.
  • It underscores the importance of thorough histological examination for accurate diagnosis and tailored treatment strategies.
  • Further research into the pathogenesis and management of multicentric liposarcoma is warranted.
