Abstract

Stromal sarcoma of the prostate is very rare and shows rapid growth, which consequently is related to poor prognosis. Recently, we treated two cases of prostatic stromal sarcoma: one with robot-assisted laparoscopic radical prostatectomy and the other with open radical cysto-prostatectomy with an ileal conduit. To the best of our knowledge, this is the first case report of a prostatic stromal sarcoma managed by use of a robotic procedure. Here, we report of our experiences in the treatment of prostatic stromal sarcoma by use of two different methods.

  FIG. 1 (A, B) Prostate magnetic resonance imaging of the first case. T2-weighted image showing a multinodular prostatic mass protruding into the bladder with heterogeneous high signal intensity. (C) Computed tomography image of the second case. A huge prostatic mass was infiltrating the periprostatic fat and invading into the urinary bladder, seminal vesicle, and rectum.

• 

  FIG. 2 Microscopic findings of the first case. The tumor showed solid growth of neoplastic stromal cells, which had storiform spindle-shaped cells with nuclear atypia and frequent mitoses (A: H&E, ×200). The result of immunohistochemical staining was positive for CD34 (B: immunohistochemical staining, ×200).

• 

  FIG. 3 Microscopic findings of the second case. The mass consisted of hypercellular atypical spindle-shaped cells suggestive of prostatic stromal sarcoma (A: H&E, ×400). The result of immunohistochemical staining was positive for progesterone receptor (B: immunohistochemical staining, ×400).
