Pelvic mass: Schwannoma of the left seminal vesicle

Leiomyoma of the prostate: A case report and systematic review

Purpose

It is rare to find a large leiomyoma in the prostate, especially in that of a young man. This case report and systematic review provides additional information on the diagnosis, distinguishing features of imaging examinations, and treatment options.

Patients and Methods

We report on the case of a thirty-year-old man with a large leiomyoma of the prostate. MRI of the prostate revealed a round mass in the posterior lobe, 8.0 × 8.0 × 5.5 cm in size. With the assistance of laparoscopy, we resected the prostate mass completely and spared this organ. A systematic review was conducted utilizing the Preferred Reporting Items for Systematic Reviews (PRISMA) including English language published reports, from 1970 to December 2021.

Results

Urinary and erectile functioning was preserved postoperatively. After a year of follow-up, no evidence of recurrence emerged. A total of 21 studies were included for analysis.

Conclusions

A medical history of no, or few, lower urinary tract symptoms; the characteristics of a benign tumor in imaging examinations; and negative tumor markers should be included in any differential diagnosis of leiomyoma of the prostrate. A prostate biopsy should be performed before the preparative radical prostatectomy and choose nonsurgical treatment to confirm the diagnosis. Nowadays, minimally invasive surgery is the preferred effective option for this disease. It is a rare recurrence after its removal by means of surgery.

Laparoscopic surgery combined with the double-J tube implantation for the rare cystic-solid schwannoma of seminal vesicle: A Case Report and Literature Review

RATIONALE

Schwannoma is common in young and middle-aged people and occurs in the head, neck, posterior mediastinum, and retroperitoneal. Schwannoma, on the other hand, is a rare occurrence in the seminal vesicle. Early diagnosis and treatment are crucial since the disease can cause lower abdominal pain, nocturia, frequent urination, blood sperm, and other symptoms. There is no standard diagnostic or treatment guideline for seminal vesicle schwannomas currently. Therefore, the treatment experience relies on the few cases reported throughout the world.

PATIENT CONCERNS

A 45-year-old male patient discovered that the tumor beside the right side spermatophore is bigger than 3 years ago.

DIAGNOSIS

Schwannoma of seminal vesicle.

INTERVENTIONS

Ureter double-J tube implantation and laparoscopic surgery for schwannoma of seminal vesicle.

OUTCOMES

The operation process went smoothly. And the patient was no discomfort after half a year.

CONCLUSION

Schwannoma of the seminal vesicle is very rare in the clinic, and the imaging examination was not conclusive. The diagnosis mainly depends on pathological results. Surgical resection is the best treatment method for schwannoma. In surgery for schwannoma of seminal vesicle, combined with the ureter double-J tube implantation are many benefits. This case is an excellent example of the seminal vesicle schwannomas.

A giant retrovesical cystic mass: A rarest of rare with a management dilemma

A 32-year-old man investigated for subfertility and bladder outlet obstruction. He had a palpable pelvic mass and computerized tomography (CT) pelvis demonstrated that a large cystic mass (15cm) arising from right side seminal vesicle, and another small cyst from left side seminal vesicle with unilateral hydroureteronephrosis. Following a futile attempt of endoscopic drainage, mass was excised in toto via lower midline laparotomy. Pathological examination and immunocytochemistry confirmed the mass to be an extremely rare seminal vesicle Schwannoma. To our knowledge, there are few unilateral seminal vesicle schwannomas reported in literature published in English language up to date.

Multiple schwannoma of the seminal vesicle: A case report

RATIONALE

Schwannomas of the seminal vesicles are extremely rare, and only cases of single seminal vesicle schwannomas have been reported. Here, we report a case of multiple schwannoma of the seminal vesicle.

PATIENT CONCERNS

We report a rare case of multiple schwannoma of the seminal vesicle that occurred in a 48-year-old man during physical examination. Multiple mixed masses in the left region of the seminal vesicle were documented with transrectal ultrasonography and magnetic resonance imaging. The patient presented no clinical symptoms, no family history of the disease and no history of genetic disease.

DIAGNOSIS

Postoperative pathology revealed a diagnosis of seminal vesical schwannoma.

INTERVENTIONS

The patient underwent robotic-assisted laparoscopic surgery to remove the mass.

OUTCOMES

The patient recovered rapidly and the length of hospitalization was 6 days after operation. At present, there is no recurrence in 10 month follow up.

LESSONS

Whether benign or malignant, single or multiple, schwannomas still need to be diagnosed by pathology because of the limitations of examination methods. Surgical resection is still the preferred treatment.
