Four case reports on pelvic tumors with deep venous thromboses as main symptoms and literature review

To probe into the reasons for misdiagnoses of pelvic tumor as deep venous thromboses as well as the diagnostic methods and effective treatments on pelvic tumor. Four case reports on misdiagnosing pelvic tumor as deep venous thromboses and further analysis on the causes of misdiagnosis, diagnosis, and treatment with the literature study. The four cases were misdiagnosed as pelvic tumor, which actually were fibroneuroma, myxo.fluidity liposarcoma, moderately differentiated squamous cell carcinoma, and synovial sarcoma, respectively. The tumor in first case was completely removed, and the tumor in other three cases, which were malignant tumors, were resected when the tumors shrank with clear boundary and less blood supply after applied with 3. cycles of intra.arterial chemotherapy via an implanted pumpies. Pelvic tumor usually show up or is misdiagnosed as deep venous thromboses for its untypical clinical manifestation, so it should be on the alert for pelvic tumor when deep venous thromboses occurs. Tumor resection is preferred for benign tumor, and intra.arterial intervention chemotherapy should be applied first for malignant tumor followed by surgery.
