title: [A Surgical Case of Solitary Fibrous Tumor Originating from the Greater Omentum].
abstract: A36 -year-old man with intellectual disabilities consulted a local physician complaining of a cough, and an abdominal mass was observed on palpation. The patient visited our hospital for close examination. Abdominal contrasting CT revealed a mass with a clear boundary with heterogeneous contrast on the left side of his abdominal cavity. We performed a laparotomy and observed that the tumor originated from the greater omentum. The tumor size was 9×8×6 cm and its weight was 200 g. Histopathologic examination showed hyperplastic spindle-shaped tumor cells with less nuclear fission. Immunohistochemical staining showed that the tumor was positive for CD34, CD99, and bcl-2, slightly positive for p53, and negative for S-100, a- SMA, c-kit, and desmin. Based on the results, a diagnosis of solitary fibrous tumor (SFT) was made. The patient has not shown any recurrence 8 months after surgery.
