Summary
A rare seminal vesicle schwannoma in a 70-year-old man was monitored for 7 years due to its benign diagnosis. The tumor grew significantly, prompting radical resection using robot-assisted surgery.
Area of Science:
- Urology
- Surgical Oncology
- Pathology
Background:
- Seminal vesicle tumors are rare, with schwannoma being an uncommon benign diagnosis.
- Initial diagnosis of seminal vesicle schwannoma was made via ultrasound-guided biopsy in a 70-year-old male patient.
- The patient was undergoing surveillance for malignant melanoma.
Purpose of the Study:
- To report a case of a growing seminal vesicle schwannoma.
- To discuss the management of benign seminal vesicle tumors with malignant potential.
- To highlight the utility of robot-assisted surgery in seminal vesicle tumor resection.
Main Methods:
- Computed tomography (CT) for initial detection and follow-up.
- Transrectal ultrasound-guided seminal vesicle biopsy for pathological diagnosis.
- Robot-assisted laparoscopic seminal vesicle resection for definitive treatment.
Main Results:
- A left seminal vesicle tumor initially diagnosed as benign schwannoma grew from 21 mm to 47 mm over 7 years.
- Robot-assisted laparoscopic resection was successfully performed.
- Final pathology confirmed schwannoma without malignant features.
Conclusions:
- Seminal vesicle schwannomas, despite being benign, require careful monitoring due to potential for growth.
- Robot-assisted surgery offers significant advantages for seminal vesicle tumor resection, improving visualization and operative field access.
- Radical resection is indicated when growth suggests potential for malignancy or causes symptoms.
