Abstract

The present study reports a case of an extragastrointestinal stromal tumor (EGIST) originating from the seminal vesicles. A 74‑year‑old male patient with a tumor in the seminal vesicles underwent a radical spermatocystectomy due to an increased defecation frequency and a huge mass in the seminal vesicles. Ultrasonography and computed tomography (CT) initially diagnosed the mass as a tumor originating from the prostate. However, the mass was ultimately confirmed as an EGIST from the seminal vesicles following a laparotomy. According to the size, mitotic activity, cellularity, necrotic situation and immunohistochemical data, the tumor belonged to a low‑risk group. No recurrence or metastasis has been identified during six years of follow‑up observations. To the best of our knowledge, this is the first study to report this particular pathological type of EGIST.
