Abstract
Primary seminal vesicle neoplasms are uncommon, with adenocarcinoma being the
most frequent subset reported. Mixed epithelial stromal tumours (MEST) of the
seminal vesicle are rare biphasic neoplasms, with neoplastic epithelial and
stromal components. We report the case of a 73 year old, asymptomatic gentleman
whose tumour was discovered incidentally. He underwent a surgical resection of
the seminal vesicles which contained a mixed epithelial stromal tumour, with an
atypical stromal component including a distinct liposarcomatous component, which
we believe to be the first such reported case.
