Abstract

Background: Solitary Fibrous Tumor (SFT) is a rare neoplasm which lacks many clinical reports and studies; the Malignant Solitary Fibrous Tumor (MSFT) is even rarer. The literature report is infrequent and symptoms are not obvious, so it is easy to misdiagnose and missed diagnosis. Pathology and immunohistochemical analysis are the main diagnostic methods for the disease, complete surgical excision is the preferred treatment. Molecular research is a hot spot in current research. Long-term follow-up is recommended after surgery. Case Report: The patient, a 62-year-old woman, admission to hospital because of a large mass in the pelvic cavity. She had undergone partial right nephrectomy because of right kidney tumor in 1995. Total right nephrectomy was performed due to previous tumor was relapse in 2011. The tumor relapsed in posterior peritoneum one year later (The retroperitoneal tumor was surgically removed). The pathology of the tumor was later defined as the MSFT by pathological and immunohistochemical analysis. This time the tumor recurred in the pelvic cavity again and the patient was treated surgically in 2020. Six months later, the scapula recurred again, and surgery was performed in 2021 due to the insignificant effect of radiotherapy. She recovered and was discharged from the hospital. She is still being follow-up with no signs of recurrence now. Conclusion: SFT is very rare and the clinical symptoms are not specific, early diagnosis is difficult. The possibility of SFT should be considered when the pathology suggests spindle cell tumor in clinical work, further auxiliary examination is necessary to develop individualized treatment plan, so that give the patient all opportunities to benefit from the best possible outcomes. Surgical resection was the first choice and the margin was negative. Since SFT is prone to recurrence and metastasis, it is necessary to follow up closely after operation. If there is any abnormality, timely treatment is required.
