Primary borderline mucinous neoplasm of the testis: A case report and literature review

Testicular/paratesticular neoplasms morphologically resembling surface epithelial tumors of ovarian type are rare neoplasms. The criteria for the diagnosis and nomenclature of these tumors parallels those used for ovarian homologues. Pathologists and urologists need to be wary of this uncommon entity, excluding metastatic mucinous adenocarcinoma and herniation of mucinous tumors into paratestis/scrotal sac by careful clinicopathological correlation. Herein, we present the first case of borderline mucinous tumor of testis to be reported from India.
