Abstract：Solitary fibrous tumor(SFT)is a rare mesenchymal tumor,and vulvar SFT is particularly rare.Patients with vulvar SFT usually present with a painless mass in the vulva,the pathogenesis and etiology of which are unknown.Due to the extremely low incidence,gynecologists generally have insufficient understanding of it,which is easy to cause missed diagnoses and misdiagnoses.The data of a 33-year-old case of primary vulvar SFT were reported.The patient was admitted to the hospital due to self-conscious vulvar discomfort for 1 year,and color Doppler ultrasound showed a solid subcutaneous mass in the right labia majora.High-energy ultra pulse carbon dioxide laser vulvar mass resection was performed,and the mass appeared oval during the operation,with a size of about 3.0 cm×2.5 cm,with clear boundaries to surrounding tissues,and did not involve the muscular layer.It was diagnosed as vulvar SFT(low malignant potential)by pathology,immunohistochemistry and Demicco model risk stratification,and close follow-up was recommended.After 6 months of postoperative follow-up,no tumor recurrence or metastasis was seen.
