Summary
Low-grade myofibroblastic sarcoma (LGMS), a rare cancer, can present as a slow-growing scalp mass. Surgical excision and re-operation for remnant tumor removal led to a positive outcome for this patient.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Low-grade myofibroblastic sarcoma (LGMS) is a rare neoplastic entity characterized by myofibroblastic differentiation.
- LGMS typically exhibits a low metastatic potential but a high propensity for local recurrence.
Observation:
- A 26-year-old male presented with a palpable, hard, slow-growing right parietal scalp mass present for 12 months.
- Enhanced CT imaging revealed a well-defined, heterogeneously enhancing scalp mass measuring 3x4 cm.
Findings:
- Histopathological and immunohistochemical analyses confirmed the diagnosis of LGMS.
- Surgical excision was performed, followed by a re-operation to ensure complete removal of residual tumor tissue.
Implications:
- Complete surgical resection, including re-operation for remnant tumor, can be an effective management strategy for LGMS.
- This case highlights the importance of thorough surgical evaluation and management for localized LGMS, with a favorable prognosis observed at 14 months post-surgery.
