This systematic review of paratesticular tumors found liposarcoma most common in malignant cases and adenomatoid in benign cases. A new risk-based management algorithm was developed for clinical decision-making.
Area of Science:
- Urology
- Oncology
- Radiology
Background:
- Paratesticular tumors are rare neoplasms.
- Accurate diagnosis and management are crucial for patient outcomes.
Purpose of the Study:
- To conduct a comprehensive literature review of paratesticular tumors.
- To develop a novel management algorithm for these tumors.
Main Methods:
- Systematic review of studies from 1980-2024 adhering to PRISMA guidelines.
- PUBMED search for paratesticular tumors in patients >16 years.
- Extraction of data on histology, presentation, imaging, treatment, and outcomes.
Main Results:
- 85 studies (479 cases) analyzed: 397 malignant, 82 benign.
- Malignant: liposarcoma (40%); Benign: adenomatoid (34%).
- Painless scrotal mass common presentation for both, incidental finding for benign.
Conclusions:
- First systematic review detailing paratesticular tumor characteristics by histology.
- Developed a novel, risk-based management algorithm for clinical decision support.
