To examine the clinical, imaging, and pathological features of granular cell tumor of the extremity (GCT-E) located in the vastus medialis muscle and investigate the clinical significance of multimodal imaging in its diagnosis and surgical intervention.
Approach:
Key Findings:
GCT-E in the vastus medialis muscle is exceedingly uncommon, particularly in middle-aged men.
Multimodal imaging (ultrasound, CT, MRI, PET-CT) is useful for preoperative diagnosis and treatment planning.
Histopathological assessment and immunohistochemical analysis are definitive for diagnosing GCT-E.
Interpretation:
GCT-E is often misidentified as schwannoma, and multimodal imaging aids in delineating lesion extent and planning surgical strategies.
Limitations:
The rarity of GCT-E limits the generalizability of findings.
The roles of radiotherapy and chemotherapy in treatment remain inadequately defined.
Conclusion:
En bloc excision with negative surgical margins is the cornerstone of treatment, and preserving limb functionality is essential during radical resection.
For many referring providers, sending a patient for orthopedic care is not just about clinical expertise. It comes down to access, speed, and confidence in what happens next. How quickly will the patient be seen? Will they get a clear diagnosis without unnecessary delays? And will care feel coordinated or fragmented?
