Seminal vesicle neoplasms are extremely rare. Schwannoma is a benign tumor of the peripherical nerve sheath composed of Schwann cells. Most of these tumors are silent and become symptomatic with compression of adjacent organs and nerves. We present a case of a 72-year-old man who presented with a several months history of predominant storage lower urinary tract symptoms and painful ejaculation. Prostate-specific antigen (PSA) was within normal ranges, and imaging documented a retrovesical nodular lesion adjacent to the right seminal vesicle with 5 cm in width. We successfully performed a robotic-assisted laparoscopic surgery to excise the lesion. Anatomopathological analysis revealed a schwannoma.
