“…PNETs of seminal vesicle origin are extremely rare, with a few cases documented; in addition, they are more common in children and adolescents, making the age of our patient unusual [5]. The presentation of seminal vesicle PNETs can vary from an incidental finding during imaging to lower abdominal pain, and compressive symptoms such as voiding difficulties, dysuria, urinary frequency or constipation (Table 1) [1][2][3]4,6]. ( The primary localized seminal vesicle tumor is possibly curable; however, the secondary spread, mainly from the prostate, bladder, and rectum, is usually an advanced disease with poorer outcomes; therefore, differentiation between primary and secondary tumors is crucial.…”

Malignant tumors of the seminal vesicles are rare; they may be of epithelial or mesenchymal origin. Carcinomas are the most common and pelvic sarcoma may be confused with a primary tumor of the seminal vesicles. Little is known of the prognosis and best sequence of treatment in such sarcoma. We report a rare case of extra-skeletal Ewing sarcoma/primitive neuroectodermal tumor of the seminal vesicles in a 54-yearold man who presented with chronic lower abdominal pain, urinary retention, and severe constipation. Pelvic CT scan and MRI confirmed the presence of a soft tissue mass lesion centered on seminal vesicles. A trans-gluteal Tru-cut biopsy confirmed the diagnosis. Three cycles of the preoperative chemotherapy VAC/IE (vincristine, Adriamycin and cyclophosphamide, followed by ifosfamide and etoposide) protocol achieved an excellent clinical response.

“…They can arise from either epithelial or mesenchymal cells, with carcinomas being the most prevalent [1]. Ewing's sarcoma of the prostate and seminal vesicle is exceedingly rare in adolescents and young adults representing less than 0.1% of all primary tumors [2,3].…”

“…Various studies showed that needle biopsy findings compared to those of surgical and autopsy specimens may present a diagnostic challenge because benign characteristics on a histopathology exam does not rule out the absence of a carcinoma in a retrovesical mass. 12 Dahms et al 13 shown in a retrospective multi-institution study with 21 male patients the difficulty in diagnosis of retrovesical masses for eleven different diagnoses. Therefore, the lesion should be completely resected and RP should be considered if high-grade elements are identified.…”

Importance of an Early Diagnosis in Primary Adenocarcinoma of the Seminal Vesicle

Rare Tumors

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.

“…[2] Only two cases of PNET of seminal vesicle have been reported in the literature. [34] It is important to differentiate between primary and secondary spread as the former is a localized disease with possibility of cure while the later is usually an advanced disease with dismal prognosis.…”
