Primary seminal vesicle adenocarcinoma: a lethal yet cryptic malignancy with review of literature.

ABSTRACT

The rarity of primary seminal vesical adenocarcinoma (PSVA) coupled with mostly late and advanced presentation with high mortality makes it an unanticipated malignancy with poor prognosis. Although there has been sporadic reporting of cases, the dearth of literature makes standardised care a challenge. The detection has incorporated immunohistochemistry for establishing the site of origin as well as the differentiation of primary from metastatic cancer. Surgical management with seminal vesiculectomy continues to be the mainstay of treatment, but difficult anatomy and delayed intervention do lead to an increased chance of residual disease that may warrant further adjuvant chemoradiation. We present a case report where PSVA developed in a patient with Zinner syndrome-an observation that is extremely rare with a literature review of PSVA including the various aspects of management including contemporary diagnosis techniques.
