[Diagnosis and treatment of primary epididymal tumor: a report of 35 cases].

OBJECTIVE

To explore the diagnosis and treatment of primary epididymal tumor.

METHODS

We retrospectively analyzed the clinical data of 35 cases of pathologically confirmed primary epididymal tumor. Of the total number of patients, 10 underwent tumor excision, 23 received epididymectomy, 1 was treated by simple orchidoepididymectomy, and by radical orchidoepididymectomy with second-stage retroperitoneal lymph node dissection.

RESULTS

Postoperative pathology confirmed 33 cases of benign tumor (including 21 adenomatoid tumor, 7 leiomyoma, 4 fibroma, and 1 papillary cystadenoma), and 2 cases of malignancy (1 malignant fibrous histiocytoma and 1 adenocarcinoma). The follow-up lasted 10 months to 6 years, which revealed no recurrence, metastasis and death.

CONCLUSION

Primary epididymal tumor is difficult to be definitely diagnosed preoperatively. Surgical exploration is the first choice for those highly suspected of the disease. Tumor excision or epididymectomy can be considered for benign cases, while radical orchidoepididymectomy with retroperitoneal lymph node dissection is recommended in case of malignancy.
