Summary
Deep fibromatoses, also known as desmoid tumors, are aggressive neoplasms. This case highlights unusual imaging features, including medullary involvement, in an extra-abdominal desmoid tumor.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Deep fibromatoses (desmoid tumors) originate from connective tissues and are characterized as aggressive, benign neoplasms.
- Cross-sectional imaging is crucial for diagnosing these tumors, typically revealing enhancing solid masses without bone involvement.
Observation:
- A case of an extra-abdominal desmoid tumor affecting the teres minor muscle in a 42-year-old woman is presented.
- The tumor exhibited unusual features, including medullary involvement.
Findings:
- The desmoid tumor demonstrated medullary involvement, deviating from typical imaging presentations.
- Nuclear beta-catenin staining was negative in this specific case.
Implications:
- This case expands the understanding of desmoid tumor imaging characteristics and potential presentations.
- Recognizing unusual features is vital for accurate diagnosis and appropriate patient management.
