This report details a rare case of myxoid liposarcoma (MLS) in the abdominal wall of a 43-year-old male. Successful surgical excision and radiotherapy led to no disease recurrence after 8 months.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Liposarcoma is the most common soft tissue sarcoma, typically affecting the extremities.
- Myxoid liposarcomas (MLSs) are a distinct histologic subtype.
- Abdominal wall MLS is exceptionally rare, with no prior documented cases.
Observation:
- A 43-year-old male presented with a tumor causing tensile force on the abdominal wall.
- Computed tomography (CT) confirmed an abdominal wall tumor; laboratory tests were unremarkable.
- The tumor was surgically excised and pathologically diagnosed as MLS.
Findings:
- The excised abdominal wall tumor was confirmed as a myxoid liposarcoma.
- The patient received standard postoperative radiotherapy.
- An 8-month follow-up revealed no evidence of disease recurrence.
Implications:
- This case highlights the importance of considering rare diagnoses, such as MLS, in abdominal wall masses.
- It expands the known clinical presentations and locations for myxoid liposarcomas.
- The successful management underscores the efficacy of multimodal treatment including surgery and radiotherapy for this rare tumor.
