| Abstract: | Pelvic neurofibromatosis is a rare disease and rarely involves the prostate. A 19-year-old male presented with irritative and obstructive voiding symptoms. Magnetic resonance imaging showed a large mass extending from the sacral promontory to the perirectal and perivesical spaces and to the proximal root of the penis. The mass also involved the prostate. The characteristics of the mass were highly suggestive for neurofibroma. Prostate biopsy showed neurofibroma, and the immunohistochemistry stain for S-100 protein was positive. |
