This study describes two rare cases of stomach liposarcoma. Computed tomography (CT) revealed aggressive malignant tumors without fatty tissue, highlighting the need to consider liposarcoma in diagnosing large gastric masses.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Diagnostic Imaging

Background:

  • Liposarcoma, a malignant tumor of adipose tissue, can rarely occur in the stomach.
  • Distinguishing gastric liposarcoma from other gastric neoplasms is diagnostically challenging.
  • Computed tomography (CT) is a key imaging modality for evaluating gastric masses.

Observation:

  • Two cases of gastric liposarcoma were analyzed.
  • CT scans demonstrated aggressive malignant features in both neoplasms.
  • No fatty tissue values, typically associated with liposarcoma, were observed within the tumors on CT.

Findings:

  • Gastric liposarcomas can present atypically on CT, lacking characteristic fatty components.
  • The imaging features mimicked other aggressive malignant gastric tumors.

  • Differential diagnosis for large exophytic gastric masses must include liposarcoma.

    • Implications:

    • Radiologists and clinicians should consider liposarcoma in the differential diagnosis of large, exophytic gastric masses, even in the absence of typical fatty CT findings.
    • Accurate preoperative diagnosis of gastric liposarcoma can guide surgical planning and patient management.
    • Further research into the specific CT characteristics of atypical gastric liposarcomas may improve diagnostic accuracy.
