Hypothesis
The tumor could have escaped complete resection due to small adhesions or minimal involvement of the gut wall.
Conclusion
This case highlights the diagnostic challenges of extra-gastrointestinal stromal tumors and their potential for metastasis.
Supporting Evidence
- The patient was initially treated for a uterine leiomyosarcoma before the correct diagnosis was made.
- Immunohistochemical analysis confirmed the presence of CD117 (KIT) positivity.
- The tumor was misdiagnosed for four years, leading to delayed treatment.
- Metastasis to skeletal muscles and subcutaneous fat from EGISTs has not been previously reported.
Takeaway
A woman had a tumor that was wrongly diagnosed for years, and it spread to her gluteal area before the correct diagnosis was made.
Methodology
The case involved surgical resection and immunohistochemical analysis of the tumor.
Limitations
The tumor was misdiagnosed for four years, which may have affected treatment outcomes.
Participant Demographics
A 56-year-old woman.
