Solitary fibrous tumor (SFT) is a rare tumor of soft tissues, which mostly arises from the pleura. Although extrathoracic SFT has been commonly described, that of the vulva is extremely rare. We report the case of a full-term female neonate who was referred to our institution with a vulvar mass suspected as inguinal hernia. CT showed a 18 × 14 × 14 mm soft tissue tumor without continuity from the abdominal cavity, and revealed multiple pulmonary metastases. MRI indicated that the vulvar mass was probably rhabdomyosarcoma. Total resection of the left vulvar mass was performed on day 11 of life. The pathological diagnosis was solitary fibrous tumor of the vulva. To the best of our knowledge, this is the first report of SFT in a neonate.
