“…The area above the prostate, however, can be enlarged and compressible if the seminal vesicle is dilated or solid if the gland contains tumor. 10 TRUS and CT scan are important diagnostic methods to improve the capability of identifying lesions of the SV. 11 Imaging is non-specific and high-grade cytologic features may be present on microscopic evaluation.…”

The prognosis of seminal vesicle (SV) adenocarcinoma is often poor due to delayed diagnosis. About 95% of the patients die in less than 3 years. Diagnosis is difficult due to the absence of early clinical signs as hematuria, hematospermia and/or dysuria. We present the case of a 61-year-old Caucasian man with a left SV mass detected by transrectal ultrasound. SV ultrasound-guided biopsy showed an adenocarcinoma. The tumor was uniformly strongly immunoreactive for cytokeratin-7 and carcinoembryonic antigen. There was no immunoreactivity for prostate-specific acid phosphatase (PSAP) and CK-20. These tumors have been reported to be also positive for CA-125. Therefore a combination of positive staining for CK-7, CEA and CA-125; with negative staining for CK-20, PSA and PSAP is the pattern of immunohistochemical findings noted for this rare tumor. The computed tomography of the abdomen-pelvis and chest X-ray was negative for metastases. The patient underwent a radical prostatectomy and lymphadenectomy. The prostate, rectum, bladder and lymph nodes were free from tumor involvement. The patient did not receive any adjuvant chemotherapy or radiation; and remains free of disease 3 years post-surgery.

“…Schwannomas, also known as neurilemmomas, are benign peripheral nerve sheath tumors ( 1 ). They are most commonly located in the head and neck, or extremities, less commonly in the mediastinum, retroperitoneum, and very rarely in the pelvis ( 2 , 3 ). A number of familial syndromes are associated with increased risk for schwannoma, including Neurofibromatosis type II, Schwannomatosis, or Carney complex ( 1 ).…”

Schwannomas, not uncommon in the head and neck, rarely occur in the pelvis. Here we describe a seminal vesicle schwannoma, the first of its kind successfully excised via robotic surgery. An otherwise well 62 year−old male presented with a complaint of rectal pain. Colonoscopy identified a mass effect on the rectum, suggesting an external lesion. A computed tomography scan revealed a right seminal vesicle mass. Transrectal ultrasound guided biopsy returned a tissue diagnosis of schwannoma. To aid in operative planning, magnetic resonance imaging of the prostate and pelvis was obtained with and without contrast. This defined a 5 × 4 × 4 cm3 mass abutting the right seminal vesicle without evidence of invasion into adjacent structures. The patient underwent an elective robotic−assisted laparoscopic resection of the mass. Final pathology demonstrated a completely excised schwannoma arising from the soft tissue adherent to the right seminal vesicle.

“…It is a rare disorder. Patients with Schwannoma of the SVs can be asymptomatic, or present with hydronephrosis, lower urinary tract symptoms, or lower abdominal pain ( 69 , 123 - 125 ). In many cases, diagnosing can be accidental, as in case reported by Fievet et al ( 126 ).…”

“…In many cases, diagnosing can be accidental, as in case reported by Fievet et al ( 126 ). Mass can be detected using TRUS, CT, and MRI ( 69 , 123 , 124 ). Arun et al diagnosed the mass using cystoscopy after TRUS and CT did not provide visible separation of prostate and SV ( 123 ).…”

Seminal vesicles (SVs) are sex accessory organs and part of male genitourinary system. They play a critical role in male fertility. Diseases of the SVs, usually results in infertility. Diseases of the SVs are extremely rare and are infrequently reported in the literature. We address the current literature of SV pathologies, symptoms, diagnosis, and treatment options. We review the clinical importance of SVs from PubMed. The current imaging modalities and instrumentation that help diagnose SV diseases are reviewed. Common pathologies including, infection, cysts, tumors, and congenital diseases of the SVs are addressed. Many times symptoms of hematospermia, pain, irritative and obstructive lower urinary tract symptoms, and infertility are presented in patients with SV diseases.

Seminal vesicle schwannoma presenting with left hydroureteronephrosis

Abstract: We report a very rare case of seminal vesicle schwannoma in a 50-year-old male, with left hydroureteronephrosis. Only five cases of seminal vesicle schwannomas have been reported in medical literature until date.
