Summary
Soft tissue sarcomas can mimic deep venous thromboses (DVTs), leading to delayed diagnosis and poorer outcomes. Physicians should consider sarcoma when evaluating patients for DVT, especially in the extremities.
Area of Science:
- Oncology
- Vascular Surgery
- Diagnostic Imaging
Background:
- Soft tissue sarcomas are rare malignancies.
- Deep venous thromboses (DVTs) are common vascular events.
- Misdiagnosis of sarcoma as DVT can lead to treatment delays.
Purpose of the Study:
- To highlight the potential for soft tissue sarcomas to initially present as DVTs.
- To raise awareness among clinicians regarding this diagnostic challenge.
Main Methods:
- Retrospective review of a health system database (1996-2004).
- Identification of patients with both soft tissue sarcoma and DVT.
- Analysis of medical records for DVT presentation preceding tumor diagnosis.
Main Results:
- Six cases identified where DVT preceded sarcoma diagnosis.
- All sarcomas located in the lower extremities, corresponding to DVT location.
- Diagnosis was delayed in five patients due to initial DVT treatment.
- Four patients had poor outcomes, with one lost to follow-up.
Conclusions:
- Soft tissue sarcomas can be misdiagnosed as DVTs, impacting patient prognosis.
- Vigilance for underlying malignancy is crucial when diagnosing DVTs.
- Early detection of sarcoma presenting as DVT is critical for improved outcomes.
