Primary Borderline Mucinous Tumors of the Testis: A Case Report and Literature Review

Abstract EN

Ovarian-type epithelial tumors of the testes and paratestes are very rare.

Mucinous subtypes of such tumors are extremely rare; only 25 cases have been reported to date.

Ovarian-type epithelial tumors are histologically classified into cystadenomas, borderline tumors, and carcinomas.

We herein report a case involving a 60-year-old man with a primary borderline mucinous tumor of the testis.

He underwent orchiectomy and has developed no recurrence for 4 years.

This is the 26th report of a mucinous tumor of the testis in the literature.

We also herein review the literature and discuss the etiology, prognosis, and treatment of mucinous tumors of the testes.
