Primary liposarcoma of the omentum: A case report

Medicine (Baltimore). 2022 Jan 7;101(1):e28344. doi: 10.1097/MD.0000000000028344.


Rationale: Omental liposarcoma is extremely rare, and only a few reports have been published in the literature. Due to the rarity of the disease, establishing a clear diagnosis and formulating a treatment plan may be challenging for clinicians.

Patient concerns: The patient was a 51-year-old woman who presented with a protruding mass and pain in the lower abdomen.

Diagnosis: Magnetic resonance imaging revealed a tumor measuring 15 cm in diameter in the pelvis. Ovarian cancer was suspected based on pre-operative imaging findings.

Interventions: An exploratory laparotomy was performed. Intra-operative analysis of the frozen section suggested a benign tumor.

Outcomes: Postoperative histopathological analysis confirmed the diagnosis of omental liposarcoma. The patient recovered well after surgery.

Lesson: This case report helps clinical oncologists to develop a comprehensive understanding of this disease and treat it accordingly.
