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

Abstract

Primary mucinous cystadenocarcinoma (MCA) of the testis is extremely rare, only 10 cases having been reported to date. Metastases of mucinous adenocarcinomas that have originated in different sites can mimic primary MAC and must be included in the differential diagnosis. We report a case of primary MCA of the tunica vaginalis testis in a 28-year-old patient who presented with a painless mass on the left side of the scrotum. We present the clinical and pathological characteristics to contribute to the further understanding of these rare tumors.
