Spindle cell tumors exhibit a relatively low occurrence rate and can manifest in various locations within the human body, including soft tissues and bones. The process of making a diagnosis is supported by conducting pathological and immunohistochemical tests. A 50-year-old female patient visited the hospital with abdominal pain that lasted about a week. Magnetic resonance imaging of the pelvis showed that this mass was independent and was not a lymph node mass, but a retroperitoneal sarcoma type mass. As part of the treatment, the mass was surgically excised, and a supracervical hysterectomy was carried out. The tumor was wrapped in a grayish-white capsule and showed a lobulating pattern. Retroperitoneal spindle cell tumors, particularly those occurring in abdominal soft tissues, are infrequently observed. Histopathological diagnosis is done in stages, and when cases are ambiguous, immunohistochemistry can provide valuable guidance in the right direction.
