Summary
Adenomatoid tumors, uncommon paratesticular neoplasms, were studied in 8 testicular and 11 epididymal cases. These tumors are benign, with local excision being the recommended treatment.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Adenomatoid tumors are rare paratesticular neoplasms, often originating from mesothelial cells.
- Epididymis is the most commonly reported site for adenomatoid tumors.
Purpose of the Study:
- To report the incidence and clinical course of testicular and epididymal adenomatoid tumors.
- To review the literature on paratesticular adenomatoid tumors.
Main Methods:
- Retrospective review of 8 testicular and 11 epididymal adenomatoid tumor cases over 13 years.
- Literature review of adenomatoid tumors of the testis and epididymis.
Main Results:
- Adenomatoid tumors constituted 6.9% of all testicular tumors (8/116), exceeding the incidence of Leydig cell tumors.
- Epididymal adenomatoid tumors represented 38% of all epididymal tumors (11/29).
- All reported cases exhibited a benign clinical course without recurrence.
Conclusions:
- Adenomatoid tumors are more common than previously thought, particularly in the epididymis.
- Local excision is the preferred treatment for both testicular and epididymal adenomatoid tumors.
- These tumors have a favorable prognosis.
