Summary
A rare pleomorphic liposarcoma, initially presenting as a lipoma, was surgically removed and treated with radiation. The tumor recurred but was managed with further radiation and chemotherapy.
Area of Science:
- Oral oncology
- Surgical pathology
- Radiation oncology
Background:
- Pleomorphic liposarcoma is a rare soft tissue malignancy.
- Gingival liposarcomas are exceptionally uncommon, with few documented cases.
- Accurate histological diagnosis is crucial for appropriate management.
Observation:
- A 24-year-old male presented with a lesion clinically resembling a lipoma in the buccal gingival sulcus.
- Histological examination revealed pleomorphic liposarcoma, a malignant tumor.
- Initial treatment involved local excision and maxillectomy with orbital function preservation.
Findings:
- Postoperative radiation therapy (5,000 rads) was administered.
- Recurrence of the tumor occurred four months after initial treatment.
- The recurrent tumor was located outside the primary surgical site.
Implications:
- Multimodality treatment including surgery, radiation, and chemotherapy may be necessary for aggressive liposarcomas.
- Close follow-up is essential due to the potential for recurrence.
- This case highlights the importance of thorough histopathological evaluation for oral soft tissue tumors.
