Fortuitous discovery of a resectable primary mucinous adenocarcinoma of the seminal vesicle in a young patient: Case report

Primary seminal vesicle adenocarcinoma is an extremely rare tumor. Accurate recognition of malignant neoplasms of the seminal vesicle is a crucial condition to establish a correct treatment that leads to improvement of long-term survival. Diagnosis of seminal vesicle carcinoma is based on many methods including imaging, biology, and pathological assessment, especially by means of immunohistochemistry. Herein, we report a case of primary mucinous adenocarcinoma of the seminal vesicle mimicking a benign congenital cyst in a 25-year-old patient, fortuitously discovered on a pelvic computer tomography scan.
